如何在wpf中实现XIPattern枚举

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <TextBox InputMethod.IsInputMethodEnabled="True" InputMethod.InputScope="Text">
            <TextBox.InputBindings>
                <KeyBinding Command="{Binding SomeCommand}" Key="Enter"/>
            </TextBox.InputBindings>
        </TextBox>
    </Grid>
</Window>

using System.Windows;
using System.Windows.Input;

namespace WpfApp
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            InputMethod.SetIsInputMethodEnabled(this.TextBox, true);
            InputMethod.SetInputScope(this.TextBox, new InputScope(new InputScopeName(InputScopeNameValue.Text)));
        }
    }
}
