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

来源:转载

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
