New project-> visual c++-& gt； Win32 project MyDLL

Note: the DLL written by C++ cannot be directly called by C#, so it is necessary to create a new C++ project and repackage the methods in the DLL into functions that can be called by C# externally.

The code in MyDLL.cpp is as follows:

extern " C " _ declspec(dll export)int add(int a，int b)

Note: the function must be preceded by extern "c" _ declspec (DLLExport), which can be referenced from outside.
