Why will the following code snippet run forever?

While(true)
{
if(MessageBox.Show("Exit now?","Close?") == DialogResult.OK)
{
Application.Exit();
}
}

How do you exit an application from within a While loop?

You don't - you have to return to the message pump so that it can return
from the Run() method.

I don't think that there is an equivalent of the C function exit().
 
Foolish me. Just after I posted, I realized I was trying to use
Application.Exit in the constructor of an object I was creating before
calling Application.Run(). Instead, I just threw an exception and caught it
in Main() so I could then return prior to running the pump. Thanks.
 
Hello Nick,

You can substitute the C function exit() with System.Environment.Exit():
