编辑条目时的实体框架DateTime格式 [英] Entity Framework DateTime format when editing entry

问题描述

我有一个Timetable模型，目前只有两个属性，一个Id和Date.定义如下:

I have a Timetable model which only has two attributes at the moment, an Id and Date. It's defined as so:

public class Timetable
{
    public int Id { get; set; }

    [Required, Column(TypeName = "Date"), DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]
    public DateTime Date { get; set; }
}

然后，我搭建了一些基本的CRUD功能，并且由于有了DisplayFormat批注，它使我能够创建日期为dd/MM/yyyy格式的时间表.但是，当我编辑现有时间表时，应用程序会在Date文本框中填充01/01/2015 00:00:00(请参见屏幕截图).

I then scaffolded some basic CRUD functionality, and thanks to the DisplayFormat annotation it's allowing me to create timetables with dates in the dd/MM/yyyy format. However, when I edit an existing timetable, the application is populating the Date text box with 01/01/2015 00:00:00 (see screenshot).

有什么方法可以使我的应用程序仅使用日期，而不使用日期和时间?

Is there any way to make my application only use the date, rather than date and time?

推荐答案

为了使用EditorFor()呈现浏览器日期选择器(<input type="date" ..>)，您需要在属性上添加以下属性(注意，ISO格式表示日期将根据浏览器的文化进行显示)

In order to render the browsers datepicker (<input type="date" ..>) using EditorFor() you need the following attributes on the property (note the ISO format means the date will be displayed in accordance with the browser culture)

[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode=true)]
[DataType(DataType.Date)]
public DateTime Date { get; set; }

并在视图中

@Html.EditorFor(m => m.Date)

请注意，旧版浏览器不支持HTML5日期输入，FireFox完全不支持HTML5日期输入-

Note the HTML5 date input is not supported in older browsers, and not at all in FireFox - see comparison here
