控件的ImeMode属性设为On
切换为中文：

                {
                    if (inputLanguage.LayoutName.IndexOf(Operator.m_InputLanguage) >= 0)
                    {
                        InputLanguage.CurrentInputLanguage = inputLanguage;
                        break;
                    }
                }
切换为英文：
foreach (InputLanguage inputLanguage in InputLanguage.InstalledInputLanguages)
                {
                    if (inputLanguage.Culture.Name.IndexOf("en") >= 0)
                    {
                        InputLanguage.CurrentInputLanguage = inputLanguage;
                        break;
                    }
