自定义显示格式属性仅设置一次

我正在通过以下代码在资源中的显示格式中设置 NullDisplayText

public class LocalizedDisplayFormatAttribute : DisplayFormatAttribute
{
    private readonly PropertyInfo _propertyInfo;

    public LocalizedDisplayFormatAttribute(string resourceKey, Type resourceType)
        : base()
    {
        this._propertyInfo = resourceType.GetProperty(resourceKey, BindingFlags.Static | BindingFlags.Public);
        if (this._propertyInfo == null)
        {
            return;
        }
        base.NullDisplayText = (string)this._propertyInfo.GetValue(this._propertyInfo.DeclaringType, null);
    }

    public new string NullDisplayText
    {
        get
        {
            return base.NullDisplayText;
        }
        set
        {
            base.NullDisplayText = value;
        }
    }
}

我使用的默认区域性是"en-US"，一旦我将区域性更改为 es-AR 并加载页面，它就可以正常工作，但是当我将区域性更改回 en-US 字段时，它不会转换回来。

我通过以下方式改变文化

protected void Application_AcquireRequestState(object sender, EventArgs e)
    {
        try
        {
            HttpCookie cookie = HttpContext.Current.Request.Cookies.Get("CurrentCulture");
            string culutureCode = cookie != null && !string.IsNullOrEmpty(cookie.Value) ? cookie.Value : "en";
            CultureInfo ci = new CultureInfo(culutureCode);
            System.Threading.Thread.CurrentThread.CurrentUICulture = ci;
            System.Threading.Thread.CurrentThread.CurrentCulture =
            CultureInfo.CreateSpecificCulture(ci.Name);
        }
        catch
        {
        }
    }

我在视图模型中使用显示格式属性作为

  public class AlarmCodeDetailsViewModel
    {
        /// <summary>
        /// Gets or sets the alarm code ID
        /// </summary>
        public int AlarmCodeID { get; set; }
        /// <summary>
        /// Gets or sets the alarm code
        /// </summary>
        [LocalizedDisplayName("Label_AlarmCode")]
        [LocalizedDisplayFormatAttribute("Warning_NullDisplayText", typeof(Properties.Resources), HtmlEncode = false)]
        public string Code { get; set; }
        /// <summary>
        /// Gets or sets the Description
        /// </summary>
        [LocalizedDisplayName("Label_Description")]
        [LocalizedDisplayFormatAttribute("Warning_NullDisplayText", typeof(Properties.Resources), HtmlEncode = false)]
        public string Description { get; set; }
        /// <summary>
        /// Gets or sets the Notes
        /// </summary>
        [LocalizedDisplayName("Label_Notes")]
        [LocalizedDisplayFormatAttribute("Warning_NullDisplayText", typeof(Properties.Resources), HtmlEncode = false)]
        public string Notes { get; set; }
    }
