C++ 之 cli窗口交互程序测试DLL

在进行cmd窗口调用DLL时，根据用户不同的输入相应的执行不同的接口进行测试，支持多线程测试：
- C++ 测试dll程序
- C# 测试dll程序

1. C++实现

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>  // 用于Windows平台的键盘输入检测
#include <windows.h> // 用于Sleep函数// 示例接口函数
void startFunction() {printf("启动功能已调用!\n");// 这里可以添加实际的启动代码
}void stopFunction() {printf("停止功能已调用!\n");// 这里可以添加实际的停止代码
}void pauseFunction() {printf("暂停功能已调用!\n");// 这里可以添加实际的暂停代码
}void resumeFunction() {printf("恢复功能已调用!\n");// 这里可以添加实际的恢复代码
}void exitFunction(int *running) {printf("退出程序...\n");*running = 0;
}// 显示帮助信息
void showHelp() {printf("\n=== 键盘按键交互测试程序 ===\n");printf("按键映射:\n");printf("  S/s - 启动功能\n");printf("  T/t - 停止功能\n");printf("  P/p - 暂停功能\n");printf("  R/r - 恢复功能\n");printf("  H/h - 显示帮助\n");printf("  Q/q - 退出程序\n");printf("============================\n\n");
}int main() {int running = 1;showHelp();printf("程序已启动，请按相应键进行测试...\n");while (running) {// 检查是否有按键按下if (_kbhit()) {char key = _getch();// 处理按键switch (key) {case 'S':case 's':startFunction();break;case 'T':case 't':stopFunction();break;case 'P':case 'p':pauseFunction();break;case 'R':case 'r':resumeFunction();break;case 'H':case 'h':showHelp();break;case 'Q':case 'q':exitFunction(&running);break;default:printf("未定义的按键: %c (按H查看帮助)\n", key);break;}}// 短暂休眠以减少CPU占用Sleep(100);}printf("程序已退出。\n");return 0;
}
