Question

Is it possible to use the new lambda expressions in Visual C++ 2010 as CLR event handlers? I’ve tried the following code:

SomeEvent += gcnew EventHandler(
    [] (Object^ sender, EventArgs^ e) {
        // code here
    }
);

It results in the following error message:

error C3364: ‘System::EventHandler’ : invalid argument for delegate constructor; delegate target needs to be a pointer to a member function

Am I attempting the impossible, or is simply my syntax wrong?

Answer 1

No can do, the C++/CLI compiler didn’t get updated to accept the lambda syntax. Fairly ironic btw given the head-start that managed code had.
