日期时间鉴于

Question

没有设置我有这部分在asp.net MVC 3视图：

<tr> 
     <td>@Html.LabelFor(x => x.DateOfBirth, new { @class = "lbl" }, "Date Of Birth") </td> 
     <td>@Html.TextBoxFor(x => x.DateOfBirth, new { @class = "w100 _dob" }) 
     <br>@Html.ValidationMessageFor(x => x.DateOfBirth)  
     </td> 
    </tr> 

但在控制器动作出生日期设为Datetime.minimum值

public ActionResult Index(IdentifyModel identifyModel) {} 

视图代码

@model CreditRegistry.Models.Helpers.IdentifyModel 

@{ 
    ViewBag.Title = "Identify"; 
    ViewBag.BreadCrumb = "Identify"; 
} 
@section BodyTitle { 
    <span>Identify</span> yourself 
} 
<ul class="extra"> 
    <li><a href="#">Receive Free Credit Report</a></li> 
    <li><a href="#">Premium Subscription</a></li> 
    <li><a href="#">FAQ</a></li> 
</ul> 


@using (Html.BeginForm("Index","Identify",FormMethod.Post,new{autocomplete="off", id="frmIdentify"})) { 


<p class="info">

何w我可以修复它

Answer 1

您需要有DateOfBirth作为DateTime?数据类型;可空的日期时间。这意味着如果DateOfBirth没有值，那么它将是NULL，而不是DateTime.MinValue。

public class IdentifyModel { 
    public DateTime? DateOfBirth {get;set;} 
} 

编辑：

我只是replciated您的问题，并找到了解决。

在您的视图模型类IdentifyModel您必须声明出生日期为null的日期时间：

public DateTime? DateOfBirth { get; set; } 

这样做停止的观点从显示01/01/0001（或任何默认的日期是），当你的看法。

然后，当我在文本框中输入“1/2/2010”并发布窗体时，DateTime值“1/2/2010”被重新发布到视图模型中。

Answer 2

这里你太复杂了。您不显示日期被设置为最小。如果DateTime字段永远不为null，则不需要可为空的类型。创建可再现问题的最简单的应用程序。设置一个断点来找出为什么不显示日期。
