[英]Get Enums for dropdownlist in asp.net mvc3
This is my enum 这是我的枚举
public class Woodshape
{
public enum eWoodShape
{
Round = 10,
Oval = 20,
Plain = 30
}
}
Now i want to add this as a dropdownlist in my controller 现在我想将此添加为控制器中的下拉列表
public ActionResult Create()
{
List<string> li = new List<string>();
FieldInfo[] myEnumFields = typeof(Woodshape.eWoodShape).GetFields();
foreach (FieldInfo myField in myEnumFields)
{
if (!myField.IsSpecialName && myField.Name.ToLower() != "notset")
{
int myValue = (int)myField.GetValue(0);
li.Add(myField.Name);
}
}
ViewBag.ddlEnumshape = new SelectList(myEnumFields, "myValue", "Name");
return View();
}
and In my view binded it as.. 在我看来,将其绑定为
<div>
@Html.DropDownList("ddlEnumshape", "-Select shape-")
/<div>
but, it is showing error 但是,它显示错误
System.Reflection.RtFieldInfo' does not contain a property with the name 'myValue'.
Could anyone help me 谁能帮我
public static IEnumerable<SelectListItem> GetListEnumWrap<TEnum>()
{
var items = new List<SelectListItem>();
if (typeof(TEnum).IsEnum)
{
foreach (var value in Enum.GetValues(typeof(TEnum)).Cast<int>())
{
var name = Enum.GetName(typeof(TEnum), value);
name = string.Format("{0}", name);
items.Add(new SelectListItem() { Value = value.ToString(), Text = name });
}
}
return items;
}
use: 采用:
@Html.DropDownListFor(m => m.Type, EnumExtensions.GetListEnumWrap<Types>())
I use this method: 我使用这种方法:
public static Dictionary<int, string> EnumToDictionary<T>()
{
return Enum.GetValues(typeof (T)).Cast<T>().ToDictionary(x => Convert.ToInt32(x), x => x.ToString());
}
ViewBag.ddlEnumshape = new SelectList(EnumToDictionary<Woodshape.eWoodShape>, "Key", "Value");
