How to allocate and de-allocate the memory thr' C# with example coding? //allocate thing X=new thing(); //deallocate x.Dispose(); //(optional if object implements dispose pattern) x=null; In managed code, memory is deallocated by the garbage collector when it's no longer needed.

If the OP really wants to talk about *memory* then the call to Dispose does nothing about memory but does allow the object to clear up non-memory resources. The setting of x to null is unnecessary and doesn;t do anything at all as x is a local variable. If x was static then setting to null would be vital in allowing the object to be cleaned up. If x were a member variable then setting it to null *might* be worth it SignatureRegards Richard Blewett DevelopMentor http://www.dotnetconsult.co.uk/weblog2 "but does allow the object to clear up non-memory resources" Which may themselves use memory. > //allocate > thing X=new thing(); [quoted text clipped - 5 lines] > In managed code, memory is deallocated by the garbage collector when it's > no longer needed.

No, but then I didn't see a method declaration either. If X is really meant to be a local variable, then setting it to null is almost certainly a bad idea - and if Thing implements IDisposable, then a using statement would almost certainly be more appropriate than manually calling Dispose.
