我知道如何处理关键事件,即
private void Page_KeyUp(object sender,KeyRoutedEventArgs e)
{
switch (e.Key)
{
case Windows.System.VirtualKey.Enter:
// handler for enter key
break;
case Windows.System.VirtualKey.A:
// handler for A key
break;
default:
break;
}
}
但是如果我需要在小写’a’和大写’A’之间辨别怎么办？另外,如果我想处理百分号’％’之类的键,该怎么办？
其他地方有答案.对于那些感兴趣的人……

{
this.InitializeComponent();
Window.Current.CoreWindow.CharacterReceived += KeyPress;
}
void KeyPress(CoreWindow sender,CharacterReceivedEventArgs args)
{
args.Handled = true;
Debug.WriteLine("KeyPress " + Convert.tochar(args.KeyCode));
return;
}
更好的是,移动Window.Current.CoreWindow.CharacterReceived = KeyPress;进入GotFocus事件处理程序,并添加Window.Current.CoreWindow.CharacterReceived – = KeyPress;进入LostFocus事件处理程序.
