C# 向TIM或者QQ自动发送中文消息【微信也是可用的】 附测试GIF

之前用C++简单的写了一个demo

现在用C#写了完整版

• 定义字符
• 定义发送数量
• 定义发送对象

注意事项

• QQ必须单独一个窗体
• 微信对象在输入名字的时候必须写微信

            keybd_event(0x01, 0, 0, 0);//激活TIM
            PostMessage(win, 0x0302, 0, 0);
        //    PostMessage(win, 0x0101, new Random().Next(65,128),0);//发送字符                                              //下面是发送回车
            PostMessage(win, 0x0100, 13, 0);
            PostMessage(win, 0x0101, 13, 0);
            keybd_event(0x11, 0, 0x0002, 0);

        }
    }
}

如果有哪位贤兄可以改成窗体也是不成问题的
