How to set list items to null C#?

Question

I have a user control called container in which I am adding other user controls at run time.

I want to remove all controls from container, I am doing container.Controls.Clear() but my controls are still in memory, how can I make them null ?

Answer 1

Calling the Clear method does not remove control handles from memory. You must explicitly call the Dispose method to avoid memory leaks.
