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() {}  
}
