本文实例讲述了C#实现异步发送邮件的方法。分享给大家供大家参考。具体如下：

下面的代码可以实现异步发送邮件，等邮件发送出去后会自动调用回调函数，这样在发送邮件时就不会卡住程序不动了

MailMessage m = new MailMessage ("item@jb51.net", "raja@jb51.net", "This is the subject for the authorized email.", "This is the body of the authorized mail!...");// Send the message using authorizationSmtpClient client = new SmtpClient("smtp.jb51.net");client.Credentials = new NetworkCredential("user", "password");client.EnableSsl = true;// Add the event handlerclient.SendCompleted += new SendCompletedEventHandler(mail_SendCompleted);// Send the message asynchronouslyclient.SendAsync(m, null);// To Cancel the send//client.SendAsyncCancel();void mail_SendCompleted(object sender, AsyncCompletedEventArgs e){ if (e.Cancelled) Console.WriteLine("Message cancelled"); else if (e.Error != null) Console.WriteLine("Error: " + e.Error.ToString()); else Console.WriteLine("Message sent");}

希望本文所述对大家的C#程序设计有所帮助。
