我正在尝试从Enum绑定Html.DropDownList。有人能帮我吗？提前谢谢。

public enum CityType
    {
        [Description("Select City")]
        Select = 0,
        [Description("A")]
        NewDelhi = 1,
        [Description("B")]
        Mumbai = 2,
        [Description("C")]
        Bangalore = 3,
        [Description("D")]
        Buxar = 4,
        [Description("E")]
        Jabalpur = 5
    }
IList<SelectListItem> list = Enum.GetValues(typeof(CityType)).Cast<CityType>().Select(x =>    new SelectListItem(){ 
    Text = EnumHelper.GetDescription(x), 
    Value = ((int)x).ToString()
}).ToList(); 
    int city=0; 
    if (userModel.HomeCity != null) city= (int)userModel.HomeCity;
ViewData["HomeCity"] = new SelectList(list, "Value", "Text", city);

 @Html.DropDownList("HomeCity",null,new { @style = "width:155px;", @class = "form-control" })
