In .NET Compact Framework, can I free memory explicitly without waiting for garbage collector to free the memory?
jsubha2009
- Jun 11th, 2010
You can also explicitly free the object from memory using the assignment statement like,Class1 obj=new Class1();obj=null;

Calling the garbage collector does nothing but let the garbage collector know you're ready for it to run. There is no way of forcing it to start as it runs on its own schedule. .Dispose() and == null are the only ways to truly free up resources.
