允許TextBox輸入中文（IME On,默認狀態）
  <TextBox Width="200" InputMethod.PreferredImeState="On" 
  InputMethod.IsInputMethodEnabled="True"
  InputMethod.PreferredImeConversionMode="FullShape,Native"></TextBox>


禁止TextBox輸入中文(IME Off)
<TextBox Width="200" InputMethod.PreferredImeState="Off" 
InputMethod.IsInputMethodEnabled="False"></TextBox>


指定默認輸入法爲中文(IME On)
<TextBox Width="200" InputLanguageManager.InputLanguage="zh-CN"></TextBox>


枚舉輸入法
foreach (System.Windows.Forms.InputLanguage lang in System.Windows.Forms.InputLanguage.InstalledInputLanguages)
if (lang.LayoutName == "Japanese")
{
  System.Windows.Forms.InputLanguage.CurrentInputLanguage = lang;
  InputMethod.Current.ImeState = InputMethodState.On;
}


檢查物理鍵盤是否存在
KeyboardCapabilities keyboardCapabilities = new Windows.Devices.Input.KeyboardCapabilities();
return  keyboardCapabilities.KeyboardPresent != 0 ? true : false;


windows自帶的虛擬鍵盤
Process.Start(Environment.GetFolderPath(Environment.SpecialFolder.System) + Path.DirectorySeparatorChar + "osk.exe");

TextBox控件，模擬鍵盤輸入（經過IME，所以目標能通過發送英文字符收到中文字符）

_uie.Focus(); _uie of TextBox System.Windows.Forms.SendKeys.SendWait("kwwl");//https://msdn.microsoft.com/zh-cn/library/system.windows.forms.sendkeys.send.aspx //從當前窗口切出後，原窗口ime狀態會不見，所以在切換前還要保持原來的ime狀態。

public static void SendInput(UIElement element, string text) {     InputManager inputManager = InputManager.Current;     InputDevice inputDevice = inputManager.PrimaryKeyboardDevice;     TextComposition composition = new TextComposition(inputManager, element, text);     TextCompositionEventArgs args = new TextCompositionEventArgs(inputDevice, composition);     args.RoutedEvent = UIElement.PreviewTextInputEvent;     element.RaiseEvent(args);     args.RoutedEvent = UIElement.TextInputEvent;     element.RaiseEvent(args); }

打開IME的一種方式 
Window mainWindow = Application.Current.MainWindow; 
WindowInteropHelper helper = new WindowInteropHelper(mainWindow); 
 IntPtr hImc = ImmGetContext(helper.Handle); 
bool imeOpen = ImmGetOpenStatus(hImc);
