Question

我正在尝试关注this示例，但却陷入了获取数据

的问题

我收到错误：

Compiler Error Message: CS1579: foreach statement cannot operate on variables of type 'RMA.Models.RMAs' because 'RMA.Models.RMAs' does not contain a public definition for 'GetEnumerator'

下面给出的代码文件：

RMAModel.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;

namespace RMA.Models
{
    public class RMAs
    {
        [Key]
        public int RNumber { get; set; }
        public int OrderNumber { get; set; }
    }
}

DBContext Model.cs

using System.Data.Entity; 
using RMA.Models;

namespace RMA.DAL
{
    public class DBContext_Model:DbContext
    {
        public DbSet<RMAs> RMAs { get; set; }
    }
}

ListController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using RMA.DAL;
using RMA.Models;

namespace RMA.Controllers
{
    public class ListController : Controller
    {
        private DBContext_Model db = new DBContext_Model();

        public ActionResult Index()
        {
            var items = db.RMAs;
            return View(items.ToList());
        }

    }
}

index.cshtml

@model RMA.Models.RMAs

@{
    ViewBag.Title = "List of RMAs";
}

<h2>Index</h2>
@foreach (RMA.Models.RMAs i in Model)
{
    <span>@i.OrderNumber</span>
}

webconfig

<connectionStrings>
    <add name="DBContext_Model"
         connectionString="Server=xx\xx;Database=xxx;Integrated Security=True;"
         providerName="System.Data.SqlClient" />
  </connectionStrings>

我在VS2010上使用mvc3 Framework和.NET Framework 4

你的@model语句应该是一个RMA列表（名称RMA应该是RMA;因为每个对象代表一个RMA：

@model IEnumerable<RMA.Models.RMAs>

获取错误：“不包含'GetEnumerator'的公共定义”
