Compiler Error C3226

  • Article

A template declaration is not allowed inside a generic declaration

Use a generic declaration inside a generic class.

The following sample generates C3226:

// C3226.cpp
// compile with: /clr
generic <class T>
ref class C {
   template <class T1>   // C3226
   ref struct S1 {};
};

The following sample demonstrates a possible resolution:

// C3226b.cpp
// compile with: /clr /c
generic <class T>
ref class C {
   generic <class T1>
   ref struct S1 {};
};
