C# 此asp.net mvc编译时错误状态是什么？

我有一个存储库类，它有

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using CrMVC.BusinessObjects;

namespace CrMVC.Models
{
    public class ConstructionRepository
    {
        private CRDataContext db = new CRDataContext();

        public IQueryable<MaterialsObj> FindAllMaterials()
        {
           var materials =  from m in db.Materials
             join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id
                select new MaterialsObj()
                   {
                       Id = Convert.ToInt64(m.Mat_id),
                       Mat_Name = m.Mat_Name,
                       Mes_Name = Mt.Name,
                   };
            return materials;

        }
    }
 }

    <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master"
 Inherits="System.Web.Mvc.ViewPage<IEnumerable<CrMVC.Models.ConstructionRepository+Materials>>" %>

但是当我编译这个时，我得到了这个错误

c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET
Files\root\19360d4c\3d21e226\App_Web_materials.aspx.7d2669f4.a8f-zsw5.0.cs(148):
error CS0426: The type name 'Materials' does not exist 
 in the type 'CrMVC.Models.ConstructionRepository'

我遗漏了什么吗？有什么建议吗

编辑：

在我的存储库类中没有名为

Materials

的类，那么为什么会出现此错误

我的查看页面有这样一个

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using CrMVC.BusinessObjects;

namespace CrMVC.Models
{
    public class ConstructionRepository
    {
        private CRDataContext db = new CRDataContext();

        public IQueryable<MaterialsObj> FindAllMaterials()
        {
           var materials =  from m in db.Materials
             join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id
                select new MaterialsObj()
                   {
                       Id = Convert.ToInt64(m.Mat_id),
                       Mat_Name = m.Mat_Name,
                       Mes_Name = Mt.Name,
                   };
            return materials;

        }
    }
 }

    <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master"
 Inherits="System.Web.Mvc.ViewPage<IEnumerable<CrMVC.Models.ConstructionRepository+Materials>>" %>

当您可能想引用

CrMVC.BusinessObjects.MaterialsObj

时，您正在ASPX中引用类型

CrMVC.Models.ConstructionRepository.Materials

。

问题在于App\u Web\u Materials.ASPX（可能是某些App\Web或App\u Web目录中的Materials.ASPX）。你能把代码贴到第148行吗？
