DLL动态链接库生成和使用（隐式调用、显示调用）

// 隐式调用 //#include"UseDLL.h" //#include<Windows.h> //#include<iostream> //using namespace std; // //#pragma comment(lib,"ConsoleApplication_GenDLL.lib") // //int main(void) //{ // cout <<"3 和 5的和为："<<endl; // int c = 0; // c = add(3, 5); // cout << c << endl; // cout << "Press any key to exit ..."; // getchar(); // return 0; //} // 显式调用 #include"UseDLL.h" #include<Windows.h> #include<iostream> using namespace std; typedef int(*addFunc)(int, int); int main(void) { addFunc _add; HINSTANCE hLibrary; hLibrary = LoadLibrary("ConsoleApplication_GenDLL.dll"); if (NULL == hLibrary) { FreeLibrary(hLibrary); return 0; } _add = (addFunc)GetProcAddress(hLibrary, "add"); if (NULL == _add) { FreeLibrary(hLibrary); return 0; } cout << "3 和 5的和为：" << endl; int c = 0; c = _add(3, 5); cout << c << endl; cout << "Press any key to exit ..."; getchar(); FreeLibrary(hLibrary); return 0; }
