I am creating delegate in C#. C# solution is class library means using dll in different application.

In C# I want to invoke C++ method(method defined by another programmer), this methods need to call on runtime. For that I am using delegate, but I don't know how to use delegate in C# and how to store C++ function details for that delegate.

below one is the high level requirement :

  1. Create C# DLL
  2. Import that DLL into C++ application.
  3. Call C# methods from C++ application code.
  4. During step 3, while invoking C# methods for particular case I needs to call C++ method for that I am using delegate. Please let me know other best approach as well.

From above mentioned steps, till step # 3 I am able to code it. For that used one of solution mentioned in below link :
