Hi The Garbage collection has implemented to manage the auto memory management of manage code basically it handles the code which runs under the environment of CLR. garbage collector knows about all managed resources at some point in time the GC will come along and clean up all the memory and resources associated with a managed object. The GC does not know about unmanaged resources such as files stream and handles so if you do not clean them up explicitly in your code then you will end up with memory leaks and locked resources. I suggest you to go through this example will give more idea about cleaning up unmanaged resources. http://www.gibmonks.com/c_sharp/csharpckbk2-CHP-3-SECT-31.html

The garbage collector only cleans up managed resources. If your class uses unmanaged resources then you should implement the IDisposable interface. You can then call the Dispose() method to clean up the unmanaged resources immediately. There is in fact a pattern which you can use for this purpose.
