Compiler Error CS0306

  • Article

The type 'type' may not be used as a type argument

The type used as a type parameter is not allowed. This could be because the type is a pointer type.

The following example generates CS0306:

// CS0306.cs
class C<T>
{
}

class M
{
    // CS0306 – int* not allowed as a type parameter
     C<int*> f;
}
