1、Dll相关代码
MyDll.h
- #ifdef DLL1_API
- #else
- #define DLL1_API extern "C" __declspec(dllimport)
- #endif
- DLL1_API int Add(int a,int b);
- DLL1_API int Sub(int a,int b);
- class __declspec(dllexport) Person
- {
- public:
- Person(char *name);
- char* m_Name;
- int m_Age;
- };
MyDll.cpp
- #define DLL1_API extern "C" __declspec(dllexport)
- #include "MyDll.h"
- #include <Windows.h>
- #include <stdio.h>
- #pragma comment(linker,"/DLL")
- #pragma comment(linker,"/ENTRY:DllMain")
- int Add(int a,int b)
- {
- return a+b;
- }
- int Sub(int a,int b)
- {
- return a-b;
- }
- Person::Person(char *name)
- {
- m_Name = name;
- }

2、调用dll中类
Main.cpp
- #include <iostream.h>
- #include <stdio.h>
- #include <windows.h>
- #include "MyDll.h"
- #pragma comment(lib,"MyDll.lib")
- void main()
- {
- int x=3;
- int y=9;
- int z=Add(x,y);
- printf("%d+%d=%d /r/n", x,y,z);
- Person pt("123");
- cout<<pt.m_Name<<endl;
- }
