Compiler Error CS0704

Cannot do member lookup in 'type' because it is a type parameter

An inner type cannot be specified through a type parameter. Try using the desired type explicitly.

Example

The following sample generates CS0704:

// CS0704.cs
class B
{
    public class I { }
}

class C<T> where T : B
{
    T.I f;  // CS0704 – member lookup on type parameter
    // Try this instead:
    // B.I f;
}

class CMain
{
    public static void Main() {}
}
