Visual studio 使用C语言通过Visual Studio 2008发送电子邮件#

我正在将Visual Studio 2008 Express与C#一起使用。我一直在尝试让一个电子邮件例程在aspx页面的代码隐藏中工作

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

所有MSDN示例，即使是那些声明用于.NET3.5的示例，都不会编译。MailMessage类显然已经更改了几次。下面是确实可以编译的代码，但这行代码SmtpMail.Send（msg）有一条模糊的错误消息：

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

与“System.Net.Mail.SmtpClient.Send（System.Net.Mail.MailMessage）”匹配的最佳重载方法包含一些无效参数

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

有人能看到无效的争论可能是什么吗？这就是阻止这一切起作用的原因

using System.Net;
using System.Net.Mail;

MailMessage msg = new MailMessage();

msg.ToAddress = new MailAddress("someone@yourCompany.com");
msg.FromAddress = ("me@myCompany.com");
msg.CCAddress = ("boss@myCompany.com");

msg.EmailMessage = "Order message test";
msg.EmailSubject = "Order Confirmation";
msg.MailEncoding = "html";
msg.MailPriority = MailPriority.Normal.ToString();

SmtpClient SmtpMail = new SmtpClient();

SmtpMail.Host = "smtpout.secureserver.net";
SmtpMail.Port = 25;

try
{
    SmtpMail.Send(msg);    // This is where the error occurs.
}
catch (Exception ex)
{
    //  Incomplete here
}

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

看起来您正在为使用自定义包装。这些属性都不是.NET类的成员（对于我能找到的任何版本）

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

对于3.5，您将使用：

msg.To.Add(new MailAddress("someone@yourCompany.com"));
msg.From.Add(new MailAddress("me@myCompany.com"));
msg.CC.Add(new MailAddress("boss@myCompany.com"));

msg.Body = "Order message test";
msg.Subject = "Order Confirmation";
msg.BodyEncoding = Encoding.Default;
msg.Priority = MailPriority.Normal;

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

看起来您正在尝试做一些非常复杂的事情；我会先尝试一个更简单的示例，然后逐步升级。该网站有很多您可能会发现有用的资源。这是：

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

下面的示例使用C#.net 3.0框架

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

以下是我使用的额外库：

        using System.Net.Mail;  //.MailMessage
        using Microsoft.VisualBasic; //imports control characters for string formatting

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

以下是我的电子邮件功能：

        String strPassed = ""; 
        System.Web.Mail.MailMessage
        String strEmailTo = "touser@xyz.org";
        String strEmailFrom = "fromuser@xyz.org";
        String strEmailBCC = "";
        String strEmailSubject;
        String strEmailBody = "";

        strEmailSubject = "Attention User - Request Email";
        strEmailBody = "You requested your password for xyz site. <br><br>" +
            " <b> Account Information </b> ...<br> ";
        strEmailBody = strMessage;
        strEmailTo = strEmail;

        System.Net.Mail.MailMessage objMessage = new System.Net.Mail.MailMessage(strEmailFrom, strEmailTo);
        objMessage.IsBodyHtml = true;
        objMessage.Subject = strEmailSubject;
        objMessage.Body = strEmailBody;  //emailbody;

        MailAddressCollection objAddress = new MailAddressCollection();
        System.Net.Mail.SmtpClient objClientPath = new System.Net.Mail.SmtpClient();
        SmtpClient smtp = new SmtpClient();
        try
        {
            strPassed = "passed:emailed";
            objClientPath.Host = "mailhost.xyz.org";
            objClientPath.Send(objMessage); 
        }
        catch (System.Exception err)
        {
            strPassed = "failed:"+ err.ToString();//''if an error 
        }
        return strPassed;

String strPassed=“”；
System.Web.Mail.MailMessage
字符串strEmailTo=”touser@xyz.org";
字符串strEmailFrom=”fromuser@xyz.org";
字符串strEmailBCC=“”；
字符串主题；
字符串strEmailBody=“”；
strEmailSubject=“注意用户-请求电子邮件”；
strEmailBody=“您请求了xyz站点的密码

“+
“账户信息…
”；
strEmailBody=strMessage；
strEmailTo=strEmail；
System.Net.Mail.MailMessage objMessage=新系统.Net.Mail.MailMessage（strEmailFrom，strEmailTo）；
objMessage.IsBodyHtml=true；
objectmessage.Subject=strEmailSubject；
objMessage.Body=strEmailBody；//emailbody；
MailAddressCollection objAddress=新的MailAddressCollection（）；
System.Net.Mail.SmtpClient objClientPath=new System.Net.Mail.SmtpClient（）；
SmtpClient smtp=新SmtpClient（）；
尝试
{
strPassed=“已通过：通过电子邮件发送”；
objClientPath.Host=“mailhost.xyz.org”；
发送（objMessage）；
}
捕获（System.Exception错误）
{
strPassed=“failed:”+err.ToString（）；/“，如果出现错误
}
返回strPassed；

此代码的任何内容都不正确。MailMessage类没有您在代码中编写的任何属性。
