c# - 有什么方法可以更改 .NET Compact Framework 2.0 上的输入法

Question

我正在使用 C#、.NET Compact Framework 2.0 开发 Windows Mobile 应用程序。安装的操作系统是 Windows Mobile 6.0。

问题是当我使用物理键盘在文本框中输入一些文本时，一直输入韩文是因为操作系统是韩文窗口移动版。因此，我尝试以编程方式将 IME 模式更改为英语，但框架中没有方法。例如

TextBox tb = new TextBox();
tb.ImeMode = ImeMode.Alpha; // CF does't support this property

当然，一旦我使用屏幕上的软键盘更改模式，它就可以用英语工作，但我不想使用它。

我想知道这个方法和上面的代码完全一样。

有人帮帮我~~

        finally
