C# Dictionary question

Hi, if i have a dictionary in C# defined like so:

Dictionary<string, List<int>> test;

Dictionary<string, List<int>> test;

and I do

List<int> stringValue = test["string"];

List<int> stringValue = test["string"];

is the resulting variable "stringValue" a copy of

test["string"]

test["string"]

or the actual list ???
