通过asp.net c#发送邮件并不是一件复杂的事情……只要我们知道smtp端口和主机……

        MailAddress to = new MailAddress("Email Id");

        MailAddress from = new MailAddress("Email Id");

        MailMessage mail = new MailMessage(from, to);

        mail.Subject = "write your subject";
        mail.Body = "write your body message";


        SmtpClient smtp = new SmtpClient();
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;

        smtp.Credentials = new NetworkCredential(
            "Email Id", "Password");
        smtp.EnableSsl = true;

        smtp.Send(mail);

Answer 2

找到一个您可以使用的 SMTP 服务器——您的虚拟主机应该为您提供一个可以用于内部应用程序的服务器。如果没有，那么您可以使用 Gmail，如果您有 Gmail 帐户。

用于System.Net.Mail.SmtpClient连接到服务器并发送电子邮件。它有一个简单的重载方法Send，可让您在一次调用中发送邮件。

请注意，System.Web.Mail.SmtpClient已过时。

Answer 3

//create the mail message

using(SmtpClient smtp = new SmtpClient("localhost"))
{
            MailMessage mail = new MailMessage();
            //set the addresses
            mail.From = new MailAddress("salvevishal9@gmail.com.com");
            mail.To.Add("@Email");
            //set the content
            mail.Subject = "This is an email";
            mail.Body = "this is the body content of the email.";
            //send the message
        smtp.Send(mail);
}

MailAddress to = new MailAddress("Email Id");

MailAddress from = new MailAddress("Email Id");

MailMessage mail = new MailMessage(from, to);

mail.Subject = "write your subject";
mail.Body = "write your body message";


SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;

smtp.Credentials = new NetworkCredential(
    "Email Id", "Password");
smtp.EnableSsl = true;

smtp.Send(mail);
