快捷键（ctrl+Q）
.net里面怎么实现判断快捷键（ctrl+Q），我想实现如果用户同时按了这两个键，我就将程序退出，该怎么写呢，新手请教，谢谢大家了 --------------------编程问答-------------------- 自己顶下啊 --------------------编程问答-------------------- KEY_Down()事件{
if( e.code=alt+Q)
application.exit()
} --------------------编程问答--------------------
--------------------编程问答-------------------- 谢谢楼上回复，我是用select语句来判断的，为什么我写了如下语句，程序还是退不了呢？请大家指点下啊，谢谢了
from1.KeyPreview=true;
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control && e.KeyCode == Keys.Q)
{
Application.Exit();
}
}
Case e.KeyCode = Keys.Q & e.Control
Application.Exit() --------------------编程问答-------------------- 关注。 --------------------编程问答-------------------- private void Form1_Load(object sender, EventArgs e)
{
this.KeyPreview = true;
}
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if ((e.Modifiers == Keys.Control) && (e.KeyCode == Keys.Q))
{
Application.Exit();
}
} --------------------编程问答-------------------- 谢谢楼上回复，我刚又试了下，发现任何快捷键按了都不起任何作用，是怎么回事呢？是不是哪里没有设置好呢？请大家指点啊 --------------------编程问答-------------------- 我没做过``帮顶 关注``` --------------------编程问答-------------------- 你写的是VB代码吧 --------------------编程问答-------------------- 要么：注册键
--------------------编程问答-------------------- 上面的代码给你作参考，你可能需要修改一下，

你 this.KeyPreview = true; 没有？ --------------------编程问答--------------------
Case e.KeyCode = Keys.Q & e.Control
转化成一个KeyCode了,不是实际的Ctrl+Q --------------------编程问答-------------------- 建议使用if语句,如果使用switch可以参考

已经测试,比较好用 --------------------编程问答-------------------- 干嘛那么麻烦。。。
我问你 你程序里有没有退出菜单项？ 有的话直接指定菜单项的快捷键为Ctrl+Q就可以了 在属性设置里面就有

确实~
