在MVC下拉菜单中格式化日期 [英] Formatting dates in an MVC Dropdown

问题描述

我的页面上有一个下拉列表，如下所示:-

I have a dropdown list on my page as so: -

@Html.DropDownList("dd_dates", new SelectList(@Model.seasonDates), "Please Select")

其中seasonDates是日期的IList.问题在于，当日期显示在下拉列表中时，它们上也有时间.如何设置显示日期的格式，以便不包括时间.

where seasonDates is an IList of dates. The problem is that when the dates are displayed in the dropdown they also have the time on them as well. How do I format the display date so that the time is not included.

推荐答案

也许更好的方法是在模型中定义一个返回IEnumerable<SelectListItem>的属性(在模型类中):

Maybe a better way to do this would be to define a property in your model that returns IEnumerable<SelectListItem> (in your model class):

public DateTime SelectedDate {get;set;}

public IEnumerable<SelectListItem> SeasonDates
{
    get
    {
        foreach (var item in seasonDates)
            yield return new SelectListItem() 
            { 
                Text = item.ToShortDateString(), // or apply your own formatting!
                Value = item
             };
    }
}

然后在视图中使用它:

@Html.DropDownListFor(m => m.SelectedDate, @Model.SeasonDates, "Please Select")

抱歉，如果有错误，我没有打开VS来验证sytanx.

Apologies if there are errors, I dont have VS open to verify the sytanx.
