请速采纳啊 一会就被屏蔽了
回答不易本回答被提问者采纳
我不太懂C++,请问这是否C++程序哦?
这里有字数限制,我在下面贴出来
我换了个帐号,把程序贴在下面。好心人帮我看看吧~~谢谢您!

参考技术A 看第一行就知道这是C#的程序
private void button1_Click(object sender, System.EventArgs e)
如果是C++的,就会写成
private:
void button1_Click(object sender, System.EventArgs e)
而且System.EventArgs也是.NetFrame里的东东。本回答被提问者采纳 参考技术B 应该是吧 参考技术C C#
