我正试图通过C#应用程序（控制台）发送电子邮件。事实上，我想它发送电子邮件到任何类型的电子邮件，但目前如果我能让它发送到一个gmail帐户，我会很高兴

我只是想暂时把这个发送到gmail账户

整个计划：

namespace EmailAddress
{
    class Program
    {
        static void Main(string[] args)
        {
            Program test = new Program();
            test.email_send();
        }

        public void email_send()
        {
            MailMessage mail = new MailMessage();
            SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
            mail.From = new MailAddress("hg@gmail.com");
            mail.To.Add("hg@gmail.com");
            mail.Subject = "Test Mail - 1";
            mail.Body = "Your attachment is accessible on your computer!";

            System.Net.Mail.Attachment attachment;
            attachment = new System.Net.Mail.Attachment("g:/example1.txt");
            mail.Attachments.Add(attachment);

            SmtpServer.Port = 587;
            SmtpServer.Credentials = new System.Net.NetworkCredential("your mail@gmail.com", "your password");
            SmtpServer.EnableSsl = true;

            SmtpServer.Send(mail);
        }
    }
}

新代码：不挂起，但不会将邮件发送到收件箱

static void Main(string[] args)
        {
            Program test = new Program();
            //test.email_send();
            test.CreateTestMessage4();
        }

        public void email_send()
        {
            MailMessage mail = new MailMessage();
            SmtpClient smtp = new SmtpClient("smtp.gmail.com");
            mail.From = new MailAddress("g@gmail.com");
            mail.To.Add("g@gmail.com");
            mail.Subject = "Test Mail - 1";
            mail.Body = "Your attachment is accessible on your computer!";

            System.Net.Mail.Attachment attachment;

            attachment = new System.Net.Mail.Attachment("g:\\example1.txt");
            mail.Attachments.Add(attachment);//list of attachements

            smtp.Port = 587;//google standard -- most of the time wouldn't not set
            smtp.EnableSsl = true;
            smtp.UseDefaultCredentials = true;
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.Credentials = new System.Net.NetworkCredential("*","*");

            smtp.Send(mail);

            Console.WriteLine("-- Sending Email --");
            Console.ReadLine();
        }

有人可以试试这个代码，看看它是否有效。由于某些原因，这不起作用，所以我希望有人对此有新的看法。我只是在类的一个实例的main方法中调用它

 public void email_send()
        {
            MailMessage mail = new MailMessage();
            SmtpClient smtp = new SmtpClient("smtp.gmail.com");
            mail.From = new MailAddress("your email address");
            mail.To.Add("your email address");
            mail.Subject = "Test Mail - 1";
            mail.Body = "Your attachment is accessible on your computer!";

            System.Net.Mail.Attachment attachment;

            attachment = new System.Net.Mail.Attachment("g:\\example1.txt");
            mail.Attachments.Add(attachment);//list of attachements

            //smtp.Port = 587;//google standard -- most of the time wouldn't not set
            //smtp.EnableSsl = true;
            //smtp.UseDefaultCredentials = true;
            //smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            //smtp.Credentials = new System.Net.NetworkCredential("your address", 
                                                                 "your password");

            smtp.Port = 587;
            smtp.Host = "smtp.gmail.com";
            smtp.UseDefaultCredentials = false;
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.EnableSsl = true;
            smtp.Credentials = new System.Net.NetworkCredential("*", "*"); smtp.Send(mail);

            Console.WriteLine("-- Sending Email --");
            Console.ReadLine();
        }

您的代码已关闭：

MailMessage mail = new MailMessage();
using (SmtpClient smtp = new SmtpClient("smtp.gmail.com")) {
    mail.From = new MailAddress("haufdoug@gmail.com");
    mail.To.Add("haufdoug@gmail.com");
    mail.Subject = "Test Mail - 1";
    mail.Body = "Your attachment is accessible on your computer!";

    System.Net.Mail.Attachment attachment;

    attachment = new System.Net.Mail.Attachment("g:\\example1.txt");
    mail.Attachments.Add(attachment);

    smtp.Port = 587;
    smtp.EnableSsl = true;
    smtp.UseDefaultCredentials = false;
    smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
    smtp.Credentials = new System.Net.NetworkCredential("your mail@gmail.com", "your password");

    smtp.Send(mail);
}

现在，关于你的其他一些问题

587端口仅由Google使用。通常，您连接到的邮件服务器会告诉您SMTP邮件使用哪个端口；谷歌说有587个

对于通过其他服务器发送，通常不设置端口号

旁注：

SmtpClient实现IDisposable接口。因此，它应该被包装在一个using子句中，以确保它在完成时被正确地处理。除非您使用的是

.SendAsync（）

方法

出于两个原因，我将变量名从

SmtpServer

更改为

smtp

。首先，命名约定。建议将方法中的变量设置为camel大小写（例如this）。其次，由于对象是

SmtpClient

，因此SmtpServer是一个误称。这些都是非常不同的事情，只是错误地命名事物是不好的做法
