只显示日期，不显示时间

在 MVC 剃刀，我把当前的日期在数据库这样. 。

model.Returndate = DateTime.Now.Date.ToShortDateString();

Since the database field is a datetime datatype and I am converting the current date to string format, this is not working.. how can I do this? I am doing the string format because I want the date in mm/dd/yyyy format and not in mm/dd/yyyy hh:mm:ss time format..

编辑:

在我的控制器里

var model = new ViewModel();
model.ReturnDate = DateTime.Now;
return PartialView("PartialView", model);

在局部视图中，我看到了

@Html.EditorFor(model => model.Returndate)

这是其显示日期为日期和时间在一起... 我想只是日期显示。现在不是时候。我希望这次剪辑能解释得更清楚。

You can apply custom date time format using ToString like:

DateTime.Now.Date.ToString("MM/dd/yyyy");

Further reading on DateTime.ToString formats pattern can be found here and here.

Edit: After your question edit, Just like what other suggested you should apply the date format at your view:

model.Returndate = DateTime.Now.Date;


@Html.EditorFor(model => model.Returndate.Date.ToString("MM/dd/yyyy"))

The date/time in the datebase won't be a formatted version at all. It'll just be the date/time itself. How you display that date/time when you extract the value from the database is a different matter. I strongly suspect you really just want:

model.Returndate = DateTime.Now.Date;

or possibly

model.Returndate = DateTime.UtcNow.Date;

Yes, if you look at the database using SQL Server Studio or whatever, you'll now see midnight - but that's irrelevant, and when you fetch the date out of the database and display it to a user, then you can apply the relevant format.

EDIT: In regard to your edited question, the problem isn't with the model - it's how you specify the view. You should use something like:

@Html.EditorFor(model => model.Returndate.Date.ToString("d"))

where d is the standard date and time format specifier for the short date pattern (which means it'll take the current cultural settings into account).

That's the bit I've been saying repeatedly - that when you display the date/time to the user, that's the time to format it as a date without a time.

EDIT: If this doesn't work, there should be a way of decorating the model or view with a format string - or something like that. I'm not really an MVC person, but it feels like there ought to be a good way of doing this declaratively...

If the column type is DateTime in SQL then it will store a time where you pass one or not.

It'd be better to save the date properly:

model.ReturnDate = DateTime.Now;

and then format it when you need to display it:

@Html.Label(Model.ReturnDate.ToShortDateString())

Or if you're using EditorFor:

@Html.EditorFor(model => model.ReturnDate.ToShortDateString())

or

@Html.EditorFor(model => model.ReturnDate.ToString("MM/dd/yyyy"))

To add a property to your model add this code:

public string ReturnDateForDisplay
{
get
{
return this.ReturnDate.ToString("d");
}
}

Then in your PartialView:

@Html.EditorFor(model => model.ReturnDateForDisplay)

EDIT:

I just want to clarify for this answer that by my saying 'If you're using EditorFor', that means you need to have an EditorFor template for the type of value you're trying to represent.

Editor templates are a cool way of managing repetitive controls in MVC:

http://coding-in.net/asp-net-mvc-3-how-to-use-editortemplates/

You can use them for naive types like String as I've done above; but they're especially great for letting you template a set of input fields for a more complicated data type.

This works if you want to display in a TextBox:

@Html.TextBoxFor(m => m.Employee.DOB, "{0:dd-MM-yyyy}")

Just had to deal with this scenario myself - found a really easy way to do this, simply annotate your property in the model like this:

[DataType(DataType.Date)]
public DateTime? SomeDateProperty { get; set; }

It will hide the time button from the date picker too.

Sorry if this answer is a little late ;)

I am not sure in Razor but in ASPX you do:

 <%if (item.Modify_Date != null)
{%>
<%=Html.Encode(String.Format("{0:D}", item.Modify_Date))%>
<%} %>

There must be something similar in Razor. Hopefully this will help someone.

You could simply convert the datetime. Something like:

@Convert.ToString(string.Format("{0:dd/MM/yyyy}", Model.Returndate))

You can modify your ViewModel as below:

[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}",ApplyFormatInEditMode = true)]

If you have a for loop such as the one below.

Change @item.StartDate to @item.StartDate.Value.ToShortDateString()

This will remove the time just in case you can't annotate your property in the model like in my case.

<table>
<tr>
<th>Type</th>
<th>Start Date</th>
</tr>
@foreach (var item in Model.TestList) {
<tr>
<td>@item.TypeName</td>
<td>@item.StartDate.Value.ToShortDateString()</td>
</tr>
}
</table>

I had some problems with the other solutions on this page, so thought I'd drop this in.

@Html.TextBoxFor(m => m.EndDate, "{0:d}", new { @class = "form-control datepicker" })

So you only need to add "{0:d}" in the second parameter and you should be good to go.

Include Data Annotations like DisplayFormat and ApplyFormatInEditMode to have the desired output.

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

Now your Bill date will show like.
