Quick and dirty .NET user event creation and handling

userEvent.cs

// BEGIN - create your argument class, subclass of EventArgs
   public class ProgressEventArgs : EventArgs
    {
         public int Min;
         public int Progress;
         public int Max;
         public string Message;
         public ProgressEventArgs(int min, int progress, int max, string msg)
         {
             if (progress > max)
                 progress = max;
             Min = min;
             Progress = progress;
             Max = max;
             Message = msg;
         }
    }
// END

// BEGIN -- create your event delegate in the class where you want to trigger the event
   public delegate void ProgressEventDelegate(ProgressEventArgs e);
// END

// BEGIN -- declare trigger your event
   // declare in your class as so
   public event ProgressEventDelegate progressEvent;
   progressEvent.Invoke(new ProgressEventArgs(0, iProgress, 10, "Beginning refresh."));
// END

// BEGIN -- trap (handle) your event, usually in your UI
   myObj.progressEvent += new ProgressEventDelegate(myObj_progressEvent);

   private void myObj_progressEvent(ProgressEventArgs e)
   {
      // your custom event handling code
   }
// END
