I hooked up an event handler to the KeyDown event of a TextBox. The event handler has an argument of type KeyEventArgs with properties Key and PlatformKeyCode. The issue is for both the 1 and ! keys pressed on the windows phone soft keyboard, the values for Key and PlatformKeyCode are D1 and 49 respectively. I cant tell which key was pressed. Also the Keyboard.Modifiers static property returns "None"

那么我如何确定按下的键?

So how do I determine the key that was pressed?

推荐答案

这是一个已知问题.

KeyDown/OnKeyDown 和KeyUp/OnKeyUp 问题

您始终可以读取输入值并根据 1/!分别.

You could always read the input values instead and act on 1 / ! seperately.
