Question

控制器操作：

 [AjaxRequestOnly, HttpPost, Authorize]
    public ActionResult AddCreditCard(CustomerCreditCardModelView cc) {
        if (!ModelState.IsValid) {
            Response.StatusCode = 400;
            return Content(Newtonsoft.Json.JsonConvert.SerializeObject(ModelState.Values.SelectMany(v => v.Errors).Select(e=>e.ErrorMessage)));
        }
        // .... do something ...        
    }

模型视图：

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
using CheckoutVC.CheckoutServiceReference;
using Newtonsoft.Json;

public class CustomerCreditCardModelView {

    [Display(Name = "Número")]
    [Required(ErrorMessage = "El Número es requerido")]
    [StringLength(20, MinimumLength = 12, ErrorMessage = "El número parece ser incorrecto")]
    [JsonIgnore, ScriptIgnore]
    public string CardNumber { get; set; }

    [Display(Name = "Código de seguridad")]
    [Required(ErrorMessage = "El Código de seguridad es requerido")]
    public string CardSecurityCode { get; set; }

    [Display(Name = "Nombre en la tarjeta")]
    [Required(ErrorMessage = "El Nombre en la tarjeta es requerido")]
    public string NameOnCard { get; set; }

    [Display(Name = "Dirección de cobro")]
    [Required(ErrorMessage = "La Dirección de cobro es requerida")]
    public string BillingAddress { get; set; }

    [Display(Name = "Mes de vencimiento")]
    [Required(ErrorMessage = "El Mes de vencimiento es requerido")]
    public int ExpirationMonth { get; set; }

    [Display(Name = "Año de vencimiento")]
    [Required(ErrorMessage = "El Año de vencimiento es requerido")]
    public int ExpirationYear { get; set; }

    [Display(Name = "Documento")]
    [Required(ErrorMessage = "El documento es requerido")]
    public string Document { get; set; }

    [Display(Name = "Tipo de tarjeta")]
    public int IdCreditCard { get; set; }

    public int IdCustomer { get; set; }
    public bool IsDeleted { get; set; }
    public int IdCustomerCreditCard { get; set; }
    public CustomerCreditCardModelView() {

    }

请求有效负载：

{"idCreditCard":1,"nameOnCard":"fdsa","billingAddress":"fdsa"}

请求回复：

["El Número es requerido","El Código de seguridad es requerido","El documento es requerido"]

正如你所看到的，除了int ExpirationMonth和int ExpirationYear应该返回验证错误（必需）但是它们没有。

实际上，modelstate只有6个键......

导致此行为的原因是什么？我想expirationMonth和expirationYear考虑[Required] DataAnnotation属性。

非常肯定在这里也是如此：mvc model validation required not working on all fields

编辑：阅读有关该问题的评论，看到问题是使用，而不是我的案例。我包括了使用部分。

这可能是因为ExpirationMonth和ExpirationYear属性是整数值。 Integer是值类型，因此它不能为null，默认值为0，从RequiredAttribute的角度来看是正确的。

您可以做的是将类型从int更改为int?，以便它可以为空。

请参阅Nullable Types。

您的viewmodel：

public class CustomerCreditCardModelView {

    [Display(Name = "Número")]
    [Required(ErrorMessage = "El Número es requerido")]
    [StringLength(20, MinimumLength = 12, ErrorMessage = "El número parece ser incorrecto")]
    [JsonIgnore, ScriptIgnore]
    public string CardNumber { get; set; }

    [Display(Name = "Código de seguridad")]
    [Required(ErrorMessage = "El Código de seguridad es requerido")]
    public string CardSecurityCode { get; set; }

    [Display(Name = "Nombre en la tarjeta")]
    [Required(ErrorMessage = "El Nombre en la tarjeta es requerido")]
    public string NameOnCard { get; set; }

    [Display(Name = "Dirección de cobro")]
    [Required(ErrorMessage = "La Dirección de cobro es requerida")]
    public string BillingAddress { get; set; }

    [Display(Name = "Mes de vencimiento")]
    [Required(ErrorMessage = "El Mes de vencimiento es requerido")]
    public int? ExpirationMonth { get; set; }

    [Display(Name = "Año de vencimiento")]
    [Required(ErrorMessage = "El Año de vencimiento es requerido")]
    public int? ExpirationYear { get; set; }

    [Display(Name = "Documento")]
    [Required(ErrorMessage = "El documento es requerido")]
    public string Document { get; set; }

    [Display(Name = "Tipo de tarjeta")]
    public int IdCreditCard { get; set; }

    public int IdCustomer { get; set; }
    public bool IsDeleted { get; set; }
    public int IdCustomerCreditCard { get; set; }
    public CustomerCreditCardModelView() {

    }
}

另一种方法是通过名称ExpirationMonth和ExpirationYear使验证更加严格我认为RangeAttribute适合您。

一些必需字段不适用于ViewModel MVC3
