如何使用C＃中的SMTPclient向gmail發送電子郵件？

Question

我正在使用outloook 2003和visual studio 2008.我想開發一個將電子郵件發送到任何域的應用程序。 但是當我嘗試向gmail，hotmail等發送電子郵件時，我的代碼失敗了。實際上所有郵件都存儲在C:\\Inetpub\\mailroot\\Queue目錄中。 請幫我如何將電子郵件發送到gmail，hotmail a / c。

提前致謝

代碼是

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("sumitdawar@hotmail.com");
message.To.Add("sumitdawar@gmail.com");            
message.Subject = "This is sample mail";
message.From = new System.Net.Mail.MailAddress("Sumit.Dhingra@niit.com");
message.Body = "this is the message body";


System.Net.Mail.SmtpClient sss = new System.Net.Mail.SmtpClient("HO-KKJ-MAIL.in.niit.com");
sss.UseDefaultCredentials = false;
sss.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
sss.Credentials = new System.Net.NetworkCredential("Sumit.Dhingrar", "password","domain");

這是使用C#在Gmail中發送電子郵件的一個很好的示例

string from = me@gmail.com; //Replace this with your own correct Gmail Address

string to = you@gmail.com //Replace this with the Email Address to whom you want to send the mail

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
 mail.To.Add(to);
 mail.From = new MailAddress(from, "One Ghost" , System.Text.Encoding.UTF8);
mail.Subject = "This is a test mail" ;
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.Body = "This is Email Body Text";
mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true ;
mail.Priority = MailPriority.High;

SmtpClient client = new SmtpClient();
//Add the Creddentials- use your own email id and password

 client.Credentials = new System.Net.NetworkCredential(from, "Password");

client.Port = 587; // Gmail works on this port
client.Host = "smtp.gmail.com";
client.EnableSsl = true; //Gmail works on Server Secured Layer
       try
        {
            client.Send(mail);
        }
        catch (Exception ex) 
        {
            Exception ex2 = ex;
            string errorMessage = string.Empty; 
            while (ex2 != null)
            {
                errorMessage += ex2.ToString();
                ex2 = ex2.InnerException;
            }
   HttpContext.Current.Response.Write(errorMessage );
        } // end try 

你確定嗎

message.From = new System.Net.Mail.MailAddress("Sumit.Dhingra@niit.com");

是對的？ 這種方法有這樣的過載嗎？
