首先探索 .net 中的 System.Net.Mail.SmtpClient 类型。该类型提供重载方法Send。

请查看此处

    public static void CreateTestMessage1(string server, int port)
    {
        string to = "[email protected]";
        string from = "[email protected]";
        string subject = "Using the new SMTP client.";
        string body = @"Using this new feature, you can send an e-mail message from an application very easily.";
        MailMessage message = new MailMessage(from, to, subject, body);
        SmtpClient client = new SmtpClient(server, port);
        // Credentials are necessary if the server requires the client 
        // to authenticate before it will send e-mail on the client's behalf.
        client.Credentials = CredentialCache.DefaultNetworkCredentials;

        try
        {
            client.Send(message);
        }
        catch (Exception ex)
        {
            Console.WriteLine("Exception caught in CreateTestMessage1(): {0}",
                  ex.ToString());
        }
    }
