WPF绑定文本块文本以更新属性，但文本将由转换器更改

public class TextConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        // 在这里进行文本转换的逻辑处理
        string text = value.ToString();
        // 这里可以根据需求进行文本的修改，比如转换为大写
        string convertedText = text.ToUpper();
        return convertedText;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
