Compiler Error C3364

'delegate': delegate constructor: argument must be pointer to member function of managed class or global function

The second parameter of the delegate's constructor takes either the address of a member function or the address of a static member function of any class. Both are treated as simple addresses.

The following sample generates C3364:

// C3364_2.cpp
// compile with: /clr

delegate int D( int, int );

ref class C {
public:
   int mf( int, int ) {
      return 1;
   }
};

int main() {
   C^ pC = gcnew C;
   System::Delegate^ pD = gcnew D( pC,pC->mf( 1, 2 ) ); // C3364

   // try the following line instead
   // System::Delegate^ pD = gcnew D(pC, &C::mf);
}
