Hi,

I was just reading about nullable types and I like that feature very much.
What dissapointed me is that nullable string is not supported.

Imagine a field (of type sting) in a database which is not assigned.

I agree with nullable only for value types but in my eyes string is kind of
a mix between a value type and a reference type.

Greetings,

Sakis
 
Sakis,

A string is a reference type. You can set a string variable to null, so
Nullable<string> is not needed.

Hope this helps.

Um:

string s = null;

Yup - so when you assign it to a string variable on the client, you
assign the variable a value of null. Where's the problem?

No, string is a reference type, very definitely.
 
You're right.

Thanx
