Compiler Error C3364
Visual Studio 2005
Error Message
'delegate': delegate constructor: argument must be pointer to member function of managed class or global functionThe 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);
}
The following sample generates C3364:
// C3364.cpp
// compile with: /clr:oldSyntax
#using <mscorlib.dll>
__delegate int D(int, int);
__gc class C {
public:
int mf(int, int) {
return 1;
}
};
int main() {
C *pC = new C;
System::Delegate *pD = new D(pC, pC->mf(1, 2)); // C3364
// try the following line instead
// System::Delegate *pD = new D(pC, &C::mf);
}
