Html.HiddenFor在ASP.NET中格式DateTime不正确 [英] Html.HiddenFor formats DateTime incorrectly in ASP.NET

问题描述

我正在C＃中编写一个ASP.NET MVC3应用程序，并发现在我的视图中调用 Html.HiddenFor 将呈现一个 DateTime 不同（和不正确），如果我要调用 Html.DisplayFor 。

模型，它的价值从有具有DisplayFormat装饰器，这似乎适用于 Html.DisplayFor 。该属性写成：

  [DisplayFormat（DataFormatString ={0：dd / MM / yyyy}，ApplyFormatInEditMode = true）] 
 public DateTime MeetingStartDate {get;组; } 
  

视图显示如下：

  @ Html.DisplayFor（model => model.MeetingStartDate）
 @ Html.HiddenFor（model => model.MeetingStartDate）
  

DisplayFor调用会将日期呈现为 16/04/2012 但是HiddenFor将会将其呈现为 value =04/16/2012 00:00:00。

我试过改变目前的文化设置一个 DateTimeFormat ，但这没有任何效果。

目前的文化是en-GB不应该打印美国的日期。

解决方案

使用TextBoxFor的视图中的替代方法如果指定日期格式和html隐藏属性。

  @ Html.TextBoxFor（model => model.CreatedDate，{0：dd / MM / yyyy HH： ss.fff}，htmlAttributes：new {@type =hidden}）
  

I'm writing an ASP.NET MVC3 application in C# and have found that calling Html.HiddenFor in my view will render a DateTime differently (and incorrectly) to if i was to call Html.DisplayFor.

The model its taking the value from does have a DisplayFormat decorator and this seems to work for Html.DisplayFor. The property in question is written as:

[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
public DateTime MeetingStartDate { get; set; }

And the view displays this using:

 @Html.DisplayFor(model => model.MeetingStartDate)
 @Html.HiddenFor(model => model.MeetingStartDate)

The DisplayFor call will render the date as 16/04/2012 however the HiddenFor will render it as value="04/16/2012 00:00:00".

I've tried changing the current culture to set a DateTimeFormat but this had no effect.

The current culture is en-GB so it shouldn't be printing en-US dates anyway.

解决方案

An in-view alternative using TextBoxFor will work if you specify the date format and the html hidden attribute.

@Html.TextBoxFor(model => model.CreatedDate, "{0:dd/MM/yyyy HH:mm:ss.fff}", htmlAttributes: new { @type = "hidden" })
