Question

I just have a general .NET inquiry:

Suppose I have a large (memory size) Class

public class BigClass { ... } 

If I add an item to an ItemControl such as a ListBox or Datagrid like this

BigClass b = new BigClass(); ListBox1.Items.Add(b); 

How is the resource usage in doing something like this? Is the added item referenced or is a copy made of the instance (causing a lot of memory usage)?

Thanks.

Answer 1

It will be added as a reference. There are no implicit copy semantics for .NET objects.
