I have a System.Type object which may be a Nullable<T>. How would I determine this at runtime?

Note: At this point I don't care what T is, I just need to know whether or not it is a Nullable.

if not..

bool IsNullableType(Type theType)
{
    return (theType.IsGenericType && 
    theType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)));
}
