Hi,
I was wondering if there is a difference between double and Double, between string and String, int and Int32 .. etc. in C#. I know that they all are primitive types, and that "int" for example is a synonym for Int32 in C#. But I was wondering - if int is a value type, does it mean that Int32 is a value type too? (it is a class as far as I know). And one more. Suggest we have the following code:

(Toggle Plain Text)

int i = 5;

Int32 i1 = 5;

i.ToString(); // i is boxed as far as i know

i1.ToString(); // is i1 boxed too ?

So i am wondering if Int32 is also being boxed.
Best regards
