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@weikejianghu.com",
"raja@weikejianghu.com",
"This is the subject for the authorized email.",
"This is the body of the authorized mail!...");
// Send the message using authorization
SmtpClient client = new SmtpClient("smtp.weikejianghu.com");
client.Credentials = new NetworkCredential("user", "password");
client.EnableSsl = true;
// Add the event handler
client.SendCompleted += new SendCompletedEventHandler(mail_SendCompleted);
// Send the message asynchronously
client.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");
}
