ASP.NET MVC控制器里捕获视图的错误验证信息(ErrorMessage)

 

ViewModel类:

    /// <summary>    /// 评论用验证视图    /// </summary>    public partial class VCreateShopComment    {        [Required(AllowEmptyStrings = false, ErrorMessage = "旺旺是必须的")]        public string WW { get; set; }        [Required(AllowEmptyStrings = false, ErrorMessage = "必须评论")]        [StringLength(200, ErrorMessage = "评论内容不能超过{0}字")]        public string CommentText { get; set; }        [Range(1, 5, ErrorMessage = "评分要在{1}到{2}之间")]        public short Score { get; set; }        //[Range(0, int.MaxValue, ErrorMessage = "您的账户无效")]        public int ID{ get; set; }    }

 

控制器

[HttpPost]public ActionResult Add(VCreateShopComment v)        {   if (ModelState.IsValid)            {              //做爱做的事            }            StringBuilder sb = new StringBuilder();            var errors = ModelState.Values;            foreach (var item in errors)            {                foreach (var item2 in item.Errors)                {
          if (!item2.ErrorMessage.IsNullOrWhiteSpace())                   {                       sb.AppendLine(item2.ErrorMessage + "<br />");                   }
} } return Content(sb.ToString()); }

 

错误的输出用2次遍历就行了,前提是,对于每个验证特性ErrorMessage 是要有的
