Is String reference type or Value type in C#?

Jenishkumar Rabadiya

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

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].
