Is a VB.net dictionary's value returned by value or reference?

If I've got a dictionary and I get an item, is it's value or reference returned?

myDictionary.Add(myKey, myDictionaryObj)
Dim obj as myObject = myDictionary.Item(myKey)

will obj have the same value as myDictionaryObj or will it have it's reference?

Does it depend on the initial object?

You will get, what you have put into the dictionary.

If the dictionary's type is a reference type (e.g. classes), you will get a reference to the object, because only the reference is stored in the dictionary.

If the dictionary's type is a value type (e.g. structures), you will get a copy of the object, because the complete value is stored in the dictionary.
