【轉載】C#後台聲明式驗證，遠離if驗證

標籤：

ViewModel

 public class ViewModel    {        [Required(ErrorMessage="標題不可為空")]        public string Title { get; set; }        public string Name { get; set; }    }

 

後台驗證代碼

public async Task<ActionResult> Save(ViewModel vm)        {            var validationContext = new ValidationContext(vm);            var results = new List<ValidationResult>();            var isValid = Validator.TryValidateObject(vm, validationContext, results, true);             if (!isValid)            {                return Json(new { Result = false, Msg = results.Select(x => x.ErrorMessage).FirstOrDefault() });            }            return Json(new { Result = true, Msg = "成功！" });        }

　　

前台調用：

$.ajax({            type: "post",            url: "/home/save",            data: "title=&name=11222332",            dataType:"json",             success: function(data) {                 alert(data.Msg);            }         });
