.net調用系統軟鍵盤（兼容win7及win10）

沒有什么技術說明，也是查詢出來的，在此做記錄

public class StartKeyBoard
    {
        public static bool isShowNumBoard = false;
        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern bool Wow64DisableWow64FsRedirection(ref IntPtr ptr);
        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern bool Wow64RevertWow64FsRedirection(IntPtr ptr);
        public static void StartKeyBoardFun()
        {
            string path = "C:/Program Files/Common Files/microsoft shared/ink/TabTip.exe";
            if (File.Exists(path))
            {
                Process p = Process.Start(path);
            }
            else
            {
                //判斷軟鍵盤是否進程是否已經存在，如果不存在進行調用
                Process[] pro = Process.GetProcessesByName("osk");
                //說明已經存在，不再進行調用
                if (pro != null && pro.Length > 0)
                    return;
                IntPtr ptr = new IntPtr();
                bool isWow64FsRedirectionDisabled = Wow64DisableWow64FsRedirection(ref ptr);
                if (isWow64FsRedirectionDisabled)
                {
                    Process.Start(@"C:\WINDOWS\system32\osk.exe");
                    bool isWow64FsRedirectionReverted = Wow64RevertWow64FsRedirection(ptr);
                }
            }
        }

    }
