This article will explain in detail how to call C++Dll in C#. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1, idle use to do a test, the reason: the last company Unity3D uses C++ encapsulated Socket with C # to call. This is an example, in fact, if some computationally heavy functions are written in C++ and then called with C #, it can optimize performance (you know) and hide (protect) the code. Say no more. Take the test.

C++ Code:

/ / CSharpMInvoke.cpp: defines the export function of the DLL application. / / # include "stdafx.h" extern "C" _ declspec (dllexport) int Add (int x, int y) {return x + y;}

C # Code:

Using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace CSharpDll {public class CPPDll {[System.Runtime.InteropServices.DllImport ("CSharpMInvoke.dll", CallingConvention=System.Runtime.InteropServices.CallingConvention.Cdecl)] public static extern int Add (int x, int y);}}

Note: copy the dll file generated by C++ (in the Bin folder) to the C# project Bin/Debug

Here is: CSharpMInvoke.dll
