//简单说明一下：
//“publicstaticexternboolRegisterHotKey()”这个函数用于注册热键。由于这个函数需要引用user32.dll动态链接库后才能使用，并且
//user32.dll是非托管代码，不能用命名空间的方式直接引用，所以需要用“DllImport”进行引入后才能使用。于是在函数前面需要加上
//“[DllImport("user32.dll",SetLastError=true)]”这行语句。
//“publicstaticexternboolUnregisterHotKey()”这个函数用于注销热键，同理也需要用DllImport引用user32.dll后才能使用。
//“publicenumKeyModifiers{}”定义了一组枚举，将辅助键的数字代码直接表示为文字，以方便使用。这样在调用时我们不必记住每一个辅
//助键的代码而只需直接选择其名称即可。
//（2）以窗体FormA为例，介绍HotKey类的使用
//在FormA的Activate事件中注册热键，本例中注册Shift+S，Ctrl+Z，Alt+D这三个热键。这里的Id号可任意设置，但要保证不被重复。
privatevoidForm_Activated(objectsender,EventArgse)

//注册热键Shift+S，Id号为100。HotKey.KeyModifiers.Shift也可以直接使用数字4来表示。
HotKey.RegisterHotKey(Handle,100,HotKey.KeyModifiers.Shift,Keys.S);
//注册热键Ctrl+B，Id号为101。HotKey.KeyModifiers.Ctrl也可以直接使用数字2来表示。
HotKey.RegisterHotKey(Handle,101,HotKey.KeyModifiers.Ctrl,Keys.B);
//注册热键Alt+D，Id号为102。HotKey.KeyModifiers.Alt也可以直接使用数字1来表示。
HotKey.RegisterHotKey(Handle,102,HotKey.KeyModifiers.Alt,Keys.D);
}
//在FormA的Leave事件中注销热键。
privatevoidFrmSale_Leave(objectsender,EventArgse)
{
//注销Id号为100的热键设定
HotKey.UnregisterHotKey(Handle,100);
