Compiler Warning C4693

'class': a sealed abstract class cannot have any instance members 'Test'

Remarks

If a type is marked sealed and abstract, it can only have static members.

This warning is automatically promoted to an error. If you wish to modify this behavior, use #pragma warning.

Example

The following example generates C4693.

// C4693.cpp
// compile with: /clr /c
public ref class Public_Ref_Class sealed abstract {
public:
   void Test() {}   // C4693
   static void Test2() {}   // OK
};
