验证在 "mvc" 控制器中不起作用

Question

我正在使用 Visual Studio 2013，并安装了 fluentvalidation mvc，但验证不起作用，尽管程序运行良好

在执行程序时，fluentvalidation 函数不工作。我已完成所有步骤，但它不起作用

     //Method in controller
     public async Task<IHttpActionResult> Save(BacklogModifyVM item)
     {
        //Validate VM
        var validator = new BacklogModifyVMValidator();
        var result = validator.Validate(item);
        if (!result.IsValid)
        {
            return InvalidDataResponse(result.Errors);
        }
      }
      //entity class
      public class BacklogModifyVM
      {
         public decimal BacklogId { get; set; }
         public string BacklogTitle { get; set; }      
         public decimal BackLogStatusId { get; set; }
         public string Owners { get; set; }        
         public decimal ProjectId { get; set; }
         public string Description { get; set; }
         public decimal? EpicId { get; set; }       
      }
      //validator class
      public class BacklogModifyVMValidator : AbstractValidator<BacklogModifyVM>
      {
          public BacklogModifyVMValidator()
          {
            RuleFor(x => x.BacklogId).GreaterThanOrEqualTo(-1).NotEqual(0);
            RuleFor(x => x.BacklogTitle).NotEmpty();
            RuleFor(x => x.BackLogStatusId).GreaterThan(0);
            RuleFor(x => x.ProjectId).GreaterThan(0);
            RuleFor(x => x.Owners).Matches(@"((\d+)((\.\d{1,2})?))$");
           }
      }
