Is String reference type or Value type in C#?

If we go to definition of string class in Visual Studio it represent string as sealed class (reference type) as per below screen shot: ![alt text][1] Then after If I tested the following code then it behaves like value type. static void Main(string[] args) { string name = "test"; ChangeName(name); Console.WriteLine(name); // this will still refer to test not test2 so behaves like ValueType Console.ReadKey(); } public static void ChangeName(string name) { name = "test2"; } We can also assign null value to string. So in this way string behaves like reference type. So I am enthusiastic to know the reason why string behaves sometime as ValueType and Sometimes as Reference Type [1]:

    string is an alias for System.String. Therefore your 'name' variable is a reference to a String object. [References are passed by value by default][1].
