Question

I know this is a strange question, but really I’m very excited to know the answer.
How do you destroy Objects in .Net, and give memory back to the heap?

Answer 1

Short Answer

System.GC.Collect(); 

is suppose to force the garbage collection to run but I’ve heard that its more of a polite asking function that may not actually have it run.

Long Answer

I believe C# uses garbage collection, so at best you can ask it to clean up but it really does it on its own time. An object is considered destroyed when there are no references to it.

For example:

Object myobject = new Object();
Object sameobject = myobject;
myobject = null;
//Garbage collection will not clean it up because sameobject is still pointing to the memory location
sameobject = null;
//Garbage collection can now clean it up
