   Removing elements from a collection that don't exist.
  This is all in C#.  Say I have class A, and I have a strongly typed collection of As.  Well, what if I do this.ACollection myCollection = new ACollection();A object1 = new A();A object2 = new A();// here I add both in.myCollection.Add(object1);myCollection.Add(object2);// then I remove onemyCollection.Remove(object1);// what happens if I try to remove the same object again?myCollection.Remove(object1);Will this throw an error?  Or will it just try it, see that it''s not there, and move on like regular?   
  Why don''t you type it into your IDE and see what happens? ;  My condern whenever attempting something like this is that it may cause some hidden bug that isn''t evident immediately.  So I ask to perhaps get an experienced opinion.  However, i''ll try it and see if I get a runtime error.--Vic--;  If you run that code it will cause your computer to implode and create a miniature black hole that will engulph the Earth in a matter of seconds.Okay, I don''t know the answer, but I''m sure it''s documented somewhere, so go RTFM.
