允许TextBox输入中文（IME On,默认状态）

  <TextBox Width="200" InputMethod.PreferredImeState="On" 

  InputMethod.IsInputMethodEnabled="True"

  InputMethod.PreferredImeConversionMode="FullShape,Native"></TextBox>

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

指定默认输入法为中文(IME On)
<TextBox Width="200" InputLanguageManager.InputLanguage="zh-CN"></TextBox>

枚举输入法
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;
}

检查物理键盘是否存在

KeyboardCapabilities keyboardCapabilities = new Windows.Devices.Input.KeyboardCapabilities();

return  keyboardCapabilities.KeyboardPresent != 0 ? true : false;

windows自带的虚拟键盘

Process.Start(Environment.GetFolderPath(Environment.SpecialFolder.System) + Path.DirectorySeparatorChar + "osk.exe");

TextBox控件，模拟键盘输入（经过IME，所以目标能通过发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
//从当前窗口切出后，原窗口ime状态会不见，所以在切换前还要保持原来的ime状态。

TextBox控件，模拟键盘输入（不经过IME，所以目标不能通过发送英文字符收到中文字符）

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);
}

打开IME的一种方式

Window mainWindow = Application.Current.MainWindow;

WindowInteropHelper helper = new WindowInteropHelper(mainWindow);

 IntPtr hImc = ImmGetContext(helper.Handle);

bool imeOpen = ImmGetOpenStatus(hImc);
