thanking you in advance

Hi Jaz,

Please view the following code sample for the usage of BeginBulkSend() paired with EndBulkSend().

///


/// BeginBulkSend with EndBulkSend demo
///

public void PerformBulkSend()
{
try
{
//Create SmtpClient
SmtpClient client = new SmtpClient("smtp.server.com", 25, "sender@domain.com", "password");
//Create all your messages
MailMessage msg1 = new MailMessage("sender@domain.com", "recepient@domain.com", "msg1", "test1");
MailMessage msg2 = new MailMessage("sender@domain.com", "recepient@domain.com", "msg2", "test2");
MailMessage msg3 = new MailMessage("sender@domain.com", "recepient@domain.com", "msg3", "test3");

// this is the deligate that registers callback function
AsyncCallback callBack = new AsyncCallback(bulkMessagesSent);
object objState = new object(); // state object

// MailMessageCollection class that contains all the messages
MailMessageCollection manyMsg = new MailMessageCollection();
manyMsg.Add(msg1);
manyMsg.Add(msg2);
manyMsg.Add(msg3);

// send the bulk emails
IAsyncResult result = client.BeginBulkSend(manyMsg, callBack, objState);

// suppose you want to cancel the above asynchronous request
// pass the result object as an argument to EndBulkSend() method
client.EndBulkSend(result);
Console.WriteLine("Main method finished.");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}

///


/// callback function that is called automatically
/// when asynchronous function BeginBulkSend() finishes
///

///
private void bulkMessagesSent(IAsyncResult result)
{
// this message will be displayed when the bulk send operation completes
Console.WriteLine("BeginBulkSend() complete.");
}
