Is there any way for a static method to access all of the non-static instances of a class?

Question

This is probably a dumb question but I'm going to ask it anyways... I am programing in C#.NET. I have a class that contains a non-static, instance EventHandler. Is it possible to trigger that EventHandler for every instance of the class that exists from a static method?? I know this is a long shot!

You can do this, but you'll need to create a static collection of all your objects:

public class Thing
{
   public static List<Thing> _things = new List<Thing>();

   public Thing()
   {
       _things.Add(this);
   }

   public static void SomeEventHandler(object value, EventHandler e)
   {
      foreach (Thing thing in _things)
      {
           // do something.
      }
   }
}

You'll want to watch out for accumulating too may "Things" . Make sure you remove them from the list when you don't need them anymore.
