How C++.net deal with delegate from a C# method?

 C++ invoke the method of a C# DLL. but C++ get a delegate method from the C# DLL, not the result that should be. 

my question is: how C++ deal with the C# delegate method? as the picture shows, "output" variable accepts the result. but it's a method.  does anybody know this case? what should I do?

Code:

output = selectedMethod->Invoke(instance, gcnew array<System::Object^>(1){ tmpObj1 });

System::Type^ typeOfOutput = output->GetType();
