梦若夕阳海
穷其一生的追求

后台逻辑层代码方法:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using BLL   (模型命名空间)

namespace namespace1(自己随意取得一个名字)
{

    public class TicketProvider
    {
        eBuulYinYeTripEntities db = new eBuulYinYeTripEntities();

 public string[] GetFromLocatijon()
        {
            string[] p = (from a in db.表名 select a.字段名).Distinct().ToArray();  //获取所有要查询的字段的值并对字段去重

            return p;
        }

}

 

前台遍历:

<select id="" name="">
    <option value="请选择">请选择</option>
        @foreach (var item in new BLL.TicketProvider().GetFromLocatijon())
        {
            if (@ViewBag.FromLocatijon == item)
            {
            <option value="@item" selected="selected">@item</option>continue;
            }
            <option value="@item">@item</option>
        }
    </select>
