Asp.net MVC 3 - 视图中显示需要从视图模型性质，这当不可吨是

Question

我有一个非常奇怪的问题

我有一个视图模型：

public class ServiceView 
{ 
    [Required] 
    [Display(Name = "Titre de l' annonce")] 
    public string NomService { get; set; } 

    [Required] 
    [Display(Name = "Description")] 
    public string DescriptionService { get; set; } 

    [Display(Name = "Adresse")] 
    public string AdresseService { get; set; } 

    [Display(Name = "Le code postal")] 
    public int CodePostalService { get; set; } 

} 

和查看其是紧我的视图模型：

@model MeilleurPresta.Models.ViewModel.ServiceView 

@{ 
    ViewBag.Title = "Déposer une offre"; 
} 

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> 
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> 


<div class="grid_23" id="body"> 

    <h3 style="padding-left: 50px"> Déposer une offre de Service </h3> 

    <div style="margin-left: 50px"> 
     @using (Html.BeginForm()) { 

      @Html.ValidationSummary(true) 

      <div class="editor-label"> 
       @Html.LabelFor(model => model.NomService) 
      </div> 
      <div class="editor-field"> 
       @Html.EditorFor(model => model.NomService) 
       @Html.ValidationMessageFor(model => model.NomService) 
      </div> 

      <div class="editor-label"> 
       @Html.LabelFor(model => model.DescriptionService) 
      </div> 
      <div class="editor-field"> 
       @Html.EditorFor(model => model.DescriptionService) 
       @Html.ValidationMessageFor(model => model.DescriptionService) 
      </div> 

      <div class="editor-label"> 
       @Html.LabelFor(model => model.AdresseService) 
      </div> 
      <div class="editor-field"> 
       @Html.EditorFor(model => model.AdresseService) 
       @Html.ValidationMessageFor(model => model.AdresseService) 
      </div> 

      <div class="editor-label"> 
       @Html.LabelFor(model => model.CodePostalService) 
      </div> 
      <div class="editor-field"> 
       @Html.EditorFor(model => model.CodePostalService) 
       @Html.ValidationMessageFor(model => model.CodePostalService) 
      </div> 

      <p> 
       <input type="submit" value="Create" /> 
      </p> 
     } 
    </div> 
</div> 

我的控制器：

public ActionResult Index() 
    { 
     return View(); 
    } 

然而，没有什么特别的，当我提交表单时，在客户端验证时，它表明该字段：Le code postal是必需的，但它不在ViewModel中。

我检查了html源代码，它生成data-val所需的类，而在我的ViewModel中没有要求attributs。

问题可能来自哪里？

感谢

因为你的int是不是空的，它标志着默认需要。你可以将int设置为int？使其可以为空，或者你可以添加这个到你的application_start来改变默认行为...

DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;
