Error verification Information (errormessage) for capturing views in ASP.

ViewModel class:

    <summary>///    reviews with validation view///    </summary> public    partial class vcreateshopcomment    {        [ Required (allowemptystrings = false, errormessage = "need to be")] public        string WW {get; set;}        [Required (allowemptystrings = false, ErrorMessage = "must comment")]        [Stringlength (errormessage = "comment cannot exceed {0} words")]        public string Commenttext {get; set;}        [Range (1, 5, errormessage = "to be scored between {1} and {2}")]        Public short score {get; set;}        [Range (0, Int. MaxValue, errormessage = "Your account is invalid")] public        int id{get; set;}    }

Controller

[Httppost]public actionresult Add (vcreateshopcomment v)        {   if (modelstate.isvalid)            {              //Love doing things            }            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 ()); }

The output of the error is traversed 2 times, provided that errormessage is needed for each validation attribute
