Question

I have a for loop which loops through and sends an email each loop. Right now im using thread.sleep() but I want the user to still be able to interact with the program, just del

Answer 1

You can spin off a new thread to send the emails so you don't lock the UI thread.

Answer 2

Try shifting the code to background Thread.

Answer 3

You need to put the method of sending mail in separated thread to keep your GUI interactive .

Thread newThread = new Thread(new ThreadStart(SendMail));
newThread.Start();

public void SendMail() 
{
    //Send mails here       
}

Answer 4

Are you running the loop on the UI thread? If so, just use Task.Factory.StartNew to run your loop in a different thread. If you need to delay the email sending at that time, put a Thread.Sleep before you actually begin looping.

It will look something like this:

private void OnButtonClick(object sender, EventArgs e)
{
    //This code happens on the UI thread
    Task.Factory.StartNew(SendEmails);
}

private void SendEmails()
{
    Thread.Sleep(500);

    foreach(var email in emailAddresses) {
        SendEmail(email);
    }
}
