Compiler Error C2933

'class' : type-class-id redefined as a typedef member of 'identifier'

Remarks

You can't use a generic or template class as a typedef member.

This error is obsolete in Visual Studio 2022 and later versions.

Examples

The following example generates C2933:

// C2933.cpp
// compile with: /c
template<class T> struct TC { };
struct MyStruct {
   typedef int TC<int>;   // C2933
};

struct TC2 { };
struct MyStruct2 {
   typedef int TC2;
};

C2933 can also occur when using generics:

// C2933b.cpp
// compile with: /clr /c
generic<class T> ref struct GC { };
struct MyStruct {
   typedef int GC<int>;   // C2933
};

ref struct GC2 { };
struct MyStruct2 {
   typedef int GC2;
};
