如何检测何时在OEM键C#中按下了(向前)斜杠键 [英] How to detect when (forward) slash key is pressed in OEM keys C#

问题描述

我正在使用wpf c#应用程序，我需要检测用户何时按"/"，但是在查找"/" e.Key时遇到了麻烦，我看到有Key.OemBackslash之类的东西，但我找不到"/"的正确事件(正斜杠)...

I'm working on wpf c# application and I need to detect when user press "/" but I'm having trouble with finding " / " e.Key, I saw there is Key.OemBackslash and stuffs like that, but I can't find right event for " / " (forward slash) ...

谢谢大家， 干杯

推荐答案

在美国键盘上应为Key.OemQuestion.但是在瑞典语键盘上，它是D7，所以要视情况而定.键盘上的键并不总是产生相同的字符.

It should be Key.OemQuestion on a US keyboard. But on a Swedish keyboard it is D7 so it depends. The keys on the keyboard doesn't always produce the same character.

根据您要执行的操作，最好处理PreviewTextInput事件:

Depending on what you are trying to do you may be better off handling the PreviewTextInput event:

protected override void OnPreviewTextInput(TextCompositionEventArgs e)
{
    base.OnPreviewTextInput(e);
    if (e.Text == "/")
    {
        Debug.WriteLine("...");
    }
}
