xamarin - 在 Xamarin.Android 中将 Keycode 转换为 char

Question

当在我的自定义 View 中按下某个键时，将调用 OnKeyPress:

public DrawView(Context context, IAttributeSet attributeSet) : base(context, attributeSet)
{
        KeyPress += OnKeyPress;
}

private void OnKeyPress(object sender, KeyEventArgs e)
{
        Keycode code = e.KeyCode;
        // How to convert to char?
}

如何将 key 代码转换为字符？例如:

"Space" -> " "
"Enter" -> "\n"
"A"     -> "A"

尝试这样的事情:

public override bool OnKeyUp (Keycode keyCode, KeyEvent e)
{
    char keyPressed = (char) e.GetUnicodeChar();
    Log.Debug (string.Format ("On KeyUp is:{0}", keyPressed));
    return base.OnKeyUp (keyCode, e);
}
