Compiler Error CS0244
Neither 'is' nor 'as' is valid on pointer types
The is and as operators are not valid for use on pointer types. For more information, see Unsafe Code and Pointers.
The following sample generates CS0244:
// CS0244.cs
// compile with: /unsafe
class UnsafeTest
{
unsafe static void SquarePtrParam (int* p)
{
bool b = p is object; // CS0244 p is pointer
}
unsafe public static void Main()
{
int i = 5;
SquarePtrParam (&i);
}
}
