[RESOLVED] situation for using "Equal" operator on reference type objects

Good Morning folks,

As you all know me, being a newbiew to .NET and C# (actually OOP also), I am practicing various aspects of the OOP concepts using C# language.
This forum responded to my concept questions and helped me quite a bit recently.

I was wondering when will in real world have to use and "Equal" operator on the reference type objects.

And if possible if some one can kindly give me a simple example, that would help quite a bit.

regards
nath
