我的表单中有一个DateTime字段。无论出于何种原因,每次我提交表单时,ModelState都会返回无效状态,并显示一条消息,表明我的日期时间字段(称为PostDate)是必需的,即使在视图模型中我没有设置必需的属性。ModelState中所需的日期时间,但从未设置为

有谁知道为什么会发生这种情况,因为我在圈子里试图弄清楚。

这里是视图模型

public class BlogViewModel 
     { 
      [Required] 
      public string Title { get; set; } 
      [Required] 
      public string Content { get; set; } 
      public bool Published { get; set; } 
      public DateTime PostDate { get; set; } 
     } 

这里是控制器动作

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

      // 
      // POST: /Admin/Blog/Create 

      [HttpPost] 
      [ValidateInput(false)] 
      public ActionResult Create(BlogViewModel model) 
      { 
       if(ModelState.IsValid) 
       { 
        model.Content = HtmlSanitizer.SanitizeHtml(model.Content); 
        Services.BlogService.CreateBlogPost(model.Title, model.Content, User.Identity.Name); 
        return RedirectToAction("Index"); 
       } 
       return View(model); 
      } 

这里是查看

您是否尝试过使用'DateTime?'代替? – bevacqua 2012-03-26 03:47:46

如果离开相应的字段清空你的模式将无效,因为DateTime是一个值类型。如果您想允许空值,则应该使用可空的DateTime:
