如何将枚举绑定到DropDownList上

private void ListType()

{
drpStatus.Items.Clear();
drpStatus.DataSource = ListTypeForEnum();
drpStatus.DataValueField = "value";
drpStatus.DataTextField = "text";
drpStatus.DataBind();
}

public static IList ListTypeForEnum()
{
ArrayList list = new ArrayList();
foreach (int i in Enum.GetValues(typeof(EnumActivityType)))
{
ListItem listitem = new ListItem(Enum.GetName(typeof(EnumActivityType), i), i.ToString());
list.Add(listitem);
} return list;
}
