Question

In C#, the following “containers” hold reference or object itself for reference types?

Queue
Stack
Array
List
Vector

For example if I do the following:

Queue<MyItem> item = new Queue<MyItem>(100);
MyItem mit = new MyItem();
item.Enqueue(mit);

The reference of the mit is copied to item or the mit object itself has been moved to item memory location?

if I say

item = null;

it will not set all objects inside item to null. Am I right?

Answer 1

The Queue contains a reference to the items in contains. Setting the Queue to null will not affect the items themselves.
