C # calls C + + dynamic-link library DLLs

Two methods were found in the process to solve the problem: a DLL library created by unmanaged C + + that needs to be called with a static method. This method can not be directly referenced in C # Reference, but to use static call method, the other blog has been described in detail, the only thing to add is that C # files need to First:

Using System.Runtime.InteropServices;

Before you can call the [DllImport] method.

Another approach is to use the CLR directly to generate a managed C++dll library.

Create a process

The routines are as follows

C + + DLLs:

Cpplibdemo.h#pragma onceusing namespace System;namespace cpplibdemo {public ref class class1{//Todo:add your methods For this class here.public:String ^getgreating () {return ' Hello World ';}};}

C # language:

Using system;using system.collections.generic;using system.linq;using system.text;using System.Threading.Tasks;            Using Cpplibdemo;namespace consoleapplication5{class Program {static void Main (string[] args) {            Class1 Clrdemo = new Class1 ();            Console.Write (Clrdemo.getgreating ());        Console.ReadLine (); }    }}
