Send Email using Background Thread
Sending Email requires some amount of time. So many times user has to wait for the page to load while the mail is being sent. And if the server is not reachable the code will try to send email until timeout.
To avoid that the email can be sent using a background thread and the user can be displayed a message immediately without delay.
Import the following Namespace
Send email using a Background thread
Thread threadSendMails;
threadSendMails = new Thread(delegate()
{
sendemail("username@gmail.com", "receiver@abc.com", "Hello", "<p>Body</p>", "C:\\MyDoc.txt", true);
});
threadSendMails.IsBackground = true;
threadSendMails.Start();
