See more: C++ C# Managed CLR
hi guys.

i have a CLR project and a c++ managed class.
i need to mimic the behavior of the "is" keyword from c# but i dont know how to do it in managed code.

part of my code:
1.C# code:
public class emailMsg : Msg
    string email;
2.C++ manged code
Msg^ msg = gcnew Msg();
if (msg is emailMsg)

the above if sentence is not compiling since managed code dont recognize the "is" keyword.
how can i solve it?

The C# 'is' operator is nothing more than an 'as' cast followed by a check for null, which is exactly the same thing you get by using dynamic_cast in C++ followed by a check for nullptr.
