推荐答案

创建如下所示的类下拉列表



试试这样

Create a class Dropdownlist like below

Try like this

using System.Collections.Generic;using System.Web.Mvc;
 
namespace EDaaS.Domain.Utilities
{
    public static class DropDownList<t>
    {
        public static SelectList LoadItems(IList<t> collection, string value, string text)
        {
            return new SelectList(collection, value, text);
        }
    }
 
}</t></t>

您的观点

Your View

@Html.DropDownListFor(model => model.CityID, (IEnumerable<SelectListItem>)ViewBag.EmployeeList, "--Select--", new { @class = "select" })

再创建一个课程

Create one more class

public class Leave
{
public int Value{get;set;}
public string Text{get;set;}
}

你的ActionResult

Your ActionResult

var list=new List<leave>{new Leave{Value=1,Text="a"},new Leave{Value=2,Text="b"}};

ViewBag.EmployeeList =
                Domain.Utilities.DropDownList<leave>.LoadItems(list, "Value", "Text");</leave></leave>
