I don't know. :-)

>>Naomi, it depends if your variable type is a Value type or a Reference type. A value type (int, decimal, etc) cannot have null assigned to it, so your best bet is to use the Nullable generic and declare like:
>Nullable<int > myValue = null;
>A reference type (string, classes) are values in the stack that point to values on the heap. When you declare a reference type as null, you are essentially point it at nothing.
