How to tell user an int typed field/property has not been set.

Hi all,

In java, if a field is Integer type, we can assign it to null indicating
that this field has not been set yet. How can we achieve that in C#? In C#,
"int" is struct, we cannot set it to null. Thank you

If you're using version 2.0, google "Nullable Types". And int is not
exactly a struct, it's a value-type, where structs are also
value-types.

If your not in .NET 2, I used to use int.minvalue as null equivilent.
It does need converting to put it in a db though.
