Compiler Error C3722

  • Article

a generic event is not allowed

The compiler only allows generic classes, structs, and functions. For more information, see Generics.

The following sample generates C3722:

// C3722.cpp
// compile with: /clr
generic <typename T>
public delegate void MyEventHandler(System::Object^ sender, System::EventArgs^ e, T optional);

generic <class T>
public ref struct MyButton {
   generic<typename U>
   event MyEventHandler<U>^ Click;   // C3722
};
