注：这是电子屏（触屏）的键盘，普通PC没有这种键盘的；

以下是调用代码：

private const Int32 WM_SYSCOMMAND = 274; private const UInt32 SC_CLOSE = 61536; [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] private static extern bool PostMessage(IntPtr hWnd, int Msg, int wParam, int lParam); [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] private static extern bool PostMessage(IntPtr hWnd, int Msg, uint wParam, uint lParam); [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] private static extern bool PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] private static extern IntPtr FindWindow(string lpClassName, string lpWindowName); [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern int RegisterWindowMessage(string lpString); //显示屏幕键盘 public static int ShowInputPanel() { try { dynamic file = "C:\\Program Files\\Common Files\\microsoft shared\\ink\\TabTip.exe"; if (!System.IO.File.Exists(file)) return -1; Process.Start(file); //return SetUnDock(); //不知SetUnDock()是什么，所以直接注释返回1 return 1; } catch (Exception) { return 255; } } //隐藏屏幕键盘 public static void HideInputPanel(){ IntPtr TouchhWnd = new IntPtr(0); TouchhWnd = FindWindow("IPTip_Main_Window", null); if (TouchhWnd == IntPtr.Zero) return; PostMessage(TouchhWnd, WM_SYSCOMMAND, SC_CLOSE, 0); }

Windows系统还有一个OSK的虚拟键盘，这个是浮动的，和自动弹出的键盘有点区别，需要的话也可以直接调用。

Process.Start(@"C:\windows\system32\osk.exe");
