Question

I have the following code:

    Dictionary<int, int> test = new Dictionary<int, int>();
    test.Add(1,1);
    test.Add(2, 2);

    Dictionary<int, int> test2 = test;
    test2.Remove(1);

Removing item from test2 is removing the item from test object too. Can you tell me how to modify items from test2 without affecting test?

Answer 1

test2 and test are the same reference to the same object (dictionary). Instantiate a new dictionary for test2.

Dictionary<int, int> test2 = new Dictionary<int, int>(test);
