C# 如何使用c在asp.net中发送电子邮件#

这是我的代码：

   protected void BtnSubmit_Click(object sender, EventArgs e)
    { 
        MailMessage msg = new MailMessage();
        msg.From = new MailAddress("Kamal.s.buqlieh@hotmail.com","Kamal");
        msg.To.Add(TxtEmailPass.Text);
        msg.Subject = "Forget Password!";
        msg.Body = "your password is:";
        SmtpClient mySmtpClient = new SmtpClient();
        mySmtpClient.Host = "www.Hotmail.com";
        NetworkCredential nc = new NetworkCredential();
        nc.UserName = "Kamal.s.buqlieh@hotmail.com";
        nc.Password = "";
        mySmtpClient.UseDefaultCredentials = true;
        mySmtpClient.Credentials = nc;
        mySmtpClient.Port = 587;
        mySmtpClient.EnableSsl = true;

        mySmtpClient.Send(msg);


    }

它一直告诉我

“无法建立连接，因为目标计算机主动拒绝157.56.198.204:587”

有人能帮我吗

您的主机地址错误。您使用了“www.Hotmail.com”

请为您的Hotmail帐户尝试以下SMTP设置：

Hotmail Incoming Mail Server (POP3) - pop3.live.com (logon using Secure Password Authentification - SPA, mail server port: 995)

Hotmail Outgoing Mail Server (SMTP) - smtp.live.com (TLS enabled, port 587)

• Hotmail SMTP服务器名称：SMTP.live.com

• Hotmail SMTP端口：25或465

---

如果您使用的是Microsoft Outlook和Outlook Connector，您可以像任何常规POP3电子邮件帐户一样定义Hotmail帐户：

Hotmail Incoming Mail Server (POP3) - pop3.live.com (logon using Secure Password Authentification - SPA, mail server port: 995)

Hotmail Outgoing Mail Server (SMTP) - smtp.live.com (TLS enabled, port 587)

IMHO防火墙阻止连接或承载服务的进程未在该端口上侦听，这可能是因为该端口根本未运行或正在另一个端口上侦听。
