如何使用C＃中的SMTPclient向gmail发送电子邮件？

我正在使用outloook 2003和visual studio 2008.我想开发一个将电子邮件发送到任何域的应用程序。 但是当我尝试向gmail，hotmail等发送电子邮件时，我的代码失败了。实际上所有邮件都存储在C:\Inetpub\mailroot\Queue目录中。 请帮我如何将电子邮件发送到gmail，hotmail a / c。

提前致谢

代码是

 System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(); message.To.Add("[e-mail]"); message.To.Add("[e-mail]"); message.Subject = "This is sample mail"; message.From = new System.Net.Mail.MailAddress("[e-mail]"); 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");

这是使用C#在Gmail中发送电子邮件的一个很好的示例

 string from = [e-mail]; //Replace this with your own correct Gmail Address string to = [e-mail] //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 

你确定吗

 message.From = new System.Net.Mail.MailAddress("[e-mail]"); 

是正确的？ 这种方法有这样的过载吗？
