System.Object Class is inherited to every class we create in .net ,at the same time it is being said that-mutiple inheritance is not supported.ie only single inheritance is possible.Then how is the object class inherited?

Well, think abt it as this way. When you create a new class, without deriving from any other class, it is automatically made a sub-class of System.Object. However, when you subclass from another class (say Base), you are inherently sub-classing from Object because of multi-level (NOT multiple) inheritance (because, Base is derived from Object).

Thats my take on it. Would be happy to know more and to know if I am missing something.

This is the fact. Object class is the ultimate Base class for all .net classes eitherer system defined or user defined. So u can hold reference of any type by instance of object class.
