System.Threading (system.dll)delegate

This event handler allows an event to be raised whenever a thread exception occurs. The System.Windows.Forms.Application.ThreadException property allows you to set one of these handlers, which takes the sender and ThreadExceptionEventArgs as arguments. The ThreadExceptionEventArgs object contains the exception raised.

public delegate void ThreadExceptionEventHandler(object sender, ThreadExceptionEventArgs e);
