Which way is preferred in expressions like this:
int? Id
{
get
{
int i;
return Int32.TryParse(Request["id"], out i) ? i : (int?)null;
}
}
is it better to cast on null or create a new Nullable<T> ?
The best is
default(int?)because it always works as expected (reference types, value types, and even in generics).
