Returning a default value. (C#)

Question

I\'m creating my own dictionary and I am having trouble implementing the TryGetValue function. When the key isn\'t found, I don\'t have anything to assign to the out parame

Answer 1

You are looking for the default keyword.

For example, in the example you gave, you want something like:

class MyEmptyDictionary : IDictionary
{
    bool IDictionary.TryGetValue (K key, out V value)
    {
        value = default(V);
        return false;
    }

    ....

}
