Compiler Error C3631

 

'function': cannot overload managed or WinRT events

A managed or WinRT event cannot be overloaded.

Example

C3631 is only reachable using /clr:oldSyntax.

The following sample generates C3631.

// C3631.cpp
// compile with: /clr:oldSyntax /c

public __gc struct S2 {
   __event void func1();   
   __event void func1(int);   // C3631 delete second declaration of func1
};

public __gc struct S1 {
   __delegate void del1();
   __delegate void del2();
   __event int add_myE(del1*) { return 0; }   
   __event int remove_myE(del1*) { return 0; }   
   __event int add_myE(del2*) { return 0; }   // C3631
   __event int remove_myE(del2*) { return 0; }   // C3631
};
