c# - 如何获取当前文化或语言中某个键的字符输入？

Question

我正在设计一个屏幕键盘，

我想将按键字符更改为与按键后将在屏幕上打印的字符相同

即按钮A将返回英文“A”，法文“Q”

我需要一个返回字符串的函数描述结果，它的参数是关键和当前的文化

另外，如果有可能知道按下班次后会发生什么是一个很好的加分项

Answer 1

我用过这段代码

    [DllImport("user32.dll")]
    public static extern int ToUnicode(uint virtualKeyCode, ScanCodeShort scanCode,
        byte[] keyboardState,
        [Out, MarshalAs(UnmanagedType.LPWStr, SizeConst = 64)]
StringBuilder receivingBuffer,
        int bufferSize, uint flags);

    public static string GetCharsFromKeys(ScanCodeShort keys)
    {
        var buf = new StringBuilder(256);
        var keyboardState = new byte[256];
        GetKeyState(VirtualKeyStates.VK_F3);
        GetKeyboardState(keyboardState);
        keyboardState[(int)System.Windows.Forms.Keys.ControlKey] = 0x00;
        int x = ToUnicode(MapVirtualKey(keys, 1), keys, keyboardState, buf, 256, 0);
        return buf.ToString();
    }


    [DllImport("user32.dll")]
    static extern short GetKeyState(VirtualKeyStates nVirtKey);

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool GetKeyboardState(byte[] lpKeyState);

在调用阶段，我使用 GetCharsFromKeys(ScanCodeShort keys) 其中 ScanCodeShort 是扫描码，而不是虚拟码
