1、c# 创建dll
建立C#编写的DLL程序AddDll,项目类型为:类库
程序代码:
using System; using System.Collections.Generic; using System.Text; namespace AddDll { public class Add { public int iadd(int a, int b) { int c = a + b; return c; } } }
2、C++编写调用程序
建立C++的Win32控制台应用程序UseDll,项目类型为:Win32控制台应用程序
配置:右键点击解决方案资源管理器中的UseDll,选择“属性”,将公共语言运行库支持设置为“公共语言运行库支持(/clr)”
程序代码:
#include "stdio.h" #using "..\debug\AddDll.dll" using namespace AddDll; int main()
{ int result; Add ^add = gcnew Add(); //生成托管类型
//gcnew creates an instance of a managed type (reference or value type) on the garbage
//collected heap. The result of the evaluation of a gcnew expression is a handle (^) to
//the type being created.
result = add->iadd(10,90); printf("%d",result); scanf("%s"); return 0; }
