c# - 在 C# ASP.NET MVC 中创建月份下拉列表

Question

这个方法看起来很笨，有点重；有没有更好的方法来创建相同的东西(它用于 MVC View 下拉列表)

private List<KeyValuePair<int, string>> getMonthListDD
{
    get
    {
        var dDur = new List<KeyValuePair<int, string>>();
        dDur.Add(new KeyValuePair<int, string>(1, "January"));
        dDur.Add(new KeyValuePair<int, string>(2, "Febuary"));
        dDur.Add(new KeyValuePair<int, string>(3, "March"));
        dDur.Add(new KeyValuePair<int, string>(4, "April"));
        dDur.Add(new KeyValuePair<int, string>(5, "May"));
        dDur.Add(new KeyValuePair<int, string>(6, "June"));
        dDur.Add(new KeyValuePair<int, string>(7, "July"));
        dDur.Add(new KeyValuePair<int, string>(8, "August"));
        dDur.Add(new KeyValuePair<int, string>(9, "September"));
        dDur.Add(new KeyValuePair<int, string>(10, "October"));
        dDur.Add(new KeyValuePair<int, string>(11, "November"));
        dDur.Add(new KeyValuePair<int, string>(12, "December"));

        return dDur;
    }
}

在您的 View 模型中，您可以拥有一个 Months 属性:

public IEnumerable<SelectListItem> Months
{
    get 
    {
        return DateTimeFormatInfo
               .InvariantInfo
               .MonthNames
               .Select((monthName, index) => new SelectListItem
               {
                   Value = (index + 1).ToString(),
                   Text = monthName
               });
    }
}

可以直接绑定(bind)到 DropDownListFor:

<%= Html.DropDownListFor(x => x.SelectedMonth, Model.Months) %>
