Catch Application Exceptions in a Windows Forms Application

You need to handle the System.Windows.Forms.Application.ThreadException event for Windows Forms. This article really helped me: http://bytes.com/forum/thread236199.html.

Application.ThreadException += new ThreadExceptionEventHandler(MyCommonExceptionHandlingMethod)

private static void MyCommonExceptionHandlingMethod(object sender, ThreadExceptionEventArgs t)
{
    //Exception handling...
}


AppDomain.UnhandledException and Application.ThreadException.

http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-2

using System;
using System.Security.Permissions;

public class Example 
{
   [SecurityPermission(SecurityAction.Demand, Flags=SecurityPermissionFlag.ControlAppDomain)]
   public static void Main()
   {
      AppDomain currentDomain = AppDomain.CurrentDomain;
      currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);

      try {
         throw new Exception("1");
      } catch (Exception e) {
         Console.WriteLine("Catch clause caught : {0} \n", e.Message);
      }

      throw new Exception("2");
   }

   static void MyHandler(object sender, UnhandledExceptionEventArgs args) 
   {
      Exception e = (Exception) args.ExceptionObject;
      Console.WriteLine("MyHandler caught : " + e.Message);
      Console.WriteLine("Runtime terminating: {0}", args.IsTerminating);
   }
}
