我正在尝试使用Html.DropDownList扩展方法,但无法弄清楚如何将它与枚举一起使用.

假设我有一个这样的枚举:

public enum ItemTypes
{
    Movie = 1,
    Game = 2,
    Book = 3
}

如何使用Html.DropDownList扩展方法创建包含这些值的下拉列表？

或者我最好的办法是简单地创建一个for循环并手动创建Html元素？

我目前在ViewModel的顶部遇到了所有这些混乱,我觉得这违反了DTO的目的.例如,这是我的一个视图模型的构造函数 -

        Dictionary<int, string> chargeGroups = new Dictionary<int, string>();
        chargeGroups.Add(1, "Administration");
        chargeGroups.Add(2, "Annual Leave");
        chargeGroups.Add(3, "Bereavement");
        chargeGroups.Add(4, "Customer Installation, Setup & Training");
        chargeGroups.Add(5, "Customer Support");
        chargeGroups.Add(6, "Internal Training & Education");
        chargeGroups.Add(7, "Sales & Marketing");
        chargeGroups.Add(8, "Sick");
        chargeGroups.Add(9, "Software Devel / Maint / Test");
        chargeGroups.Add(10, "Software Upgrade / Patch");
        chargeGroups.Add(11, "Other");
        chargeGroups.Add(12, "Other Absence");
        chargeGroups.Add(13, "Warranty");
        chargeGroups.Add(14, "Public Holiday");
        chargeGroups.Add(15, "Other Paid Leave");

        ChargeGroups = new SelectList(chargeGroups, "Key", "Value");

我的viewmodel:

    [DisplayName("Charge group")]
    public short? ChargeGroup { get; set; }

    public SelectList …
