Dbcontext类没有反映在控制器中 [英] Dbcontext Class is not reflecting in controller

问题描述

你好，在我的示例项目中，我创建了一个带有EF Dbcontext类的模型。但它没有初始化或反映在Controller类中。我正在使用Asp.net MVC 3 razor，EF DataFirst来绑定数据库。在我的其他示例应用程序工作正常。



我的模型代码

Hello in my sample project ,i have created a model with EF Dbcontext class.But it is not initializing or reflecting in the Controller Class.I am using Asp.net MVC 3 razor ,EF DataFirst to bind database.In my other sample application it works fine.

My Model Code

<blockquote class="FQ"><div class="FQA">Quote:</div>using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;

namespace InformationManagementSystem.Models
{
    public class Information
    {
        public int SID { get; set; }
        public string FName { get; set; }
        public string MName { get; set; }
        public string LName { get; set; }
        public DateTime DOB { get; set; }
        public string Sex { get; set; }
        public int Age { get; set; }
        public string Address { get; set; }
        public string DOE { get; set; }
        public string City { get; set; }
        public string Zip { get; set; }
        public string District { get; set; }
        public string Village { get; set; }
        public string Group { get; set; }
        public byte[] image { get; set; }
        public string SPCNum1 { get; set; }
        public string SPCNum2 { get; set; }
        public string SPAddress { get; set; }
        public string SPName { get; set; }
        public string FathName { get; set; }
        public string MothName { get; set; }
        public string Fam1 { get; set; }
        public string Fam2 { get; set; }
        public string Fam3 { get; set; }
        public string Fam4 { get; set; }
        public string Fam5 { get; set; }
        public string Fam6 { get; set; }
        public string Fam7 { get; set; }
        public string Fam8 { get; set; } 
        public string FamCond { get; set; }
        public string FamNotes { get; set; }
        public string Status { get; set; }
        public DateTime EntryDate { get; set; }
        public DateTime DOA { get; set; }

        public string FathOccu { get; set; }
        public string MothOccu { get; set; }



        public class InformationDbContext : DbContext
        {
            public DbSet<Information> Information { get; set; }
        }

        public class InfoDBContext : DbContext
        {

        }

    }

    
}

我的控制器代码

My Controller Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Data.Entity;
using InformationManagementSystem.Models;

namespace InformationManagementSystem.Controllers
{
    public class InformationController : Controller
    {
        //
        // GET: /Information/

        InformationDbContext db = new InformationDbContext();


        public ActionResult Index()
        {
            ViewBag.Title = "Arbaneo's Information Management System";
            return View();
        }

        public ActionResult List()
        {
            
            return View();
        }
    }
}

错误代码

InformationDbContext db = new InformationDbContext();

推荐答案

我们必须在模型类之外声明类

喜欢以下

We have to declare the class outside the model class
Like Below

<blockquote class="FQ"><div class="FQA">Quote:</div>using System.Collections.Generic;
using System.Linq;
using System.Web;
using System;
using System.Data.Entity;
 
namespace InformationManagementSystem.Models
{
    public class Information
    {
        public int SID { get; set; }
        public string FName { get; set; }
        public string MName { get; set; }
        public string LName { get; set; }
        public DateTime DOB { get; set; }
        public string Sex { get; set; }
        public int Age { get; set; }
        public string Address { get; set; }
        public string DOE { get; set; }
        public string City { get; set; }
        public string Zip { get; set; }
        public string District { get; set; }
        public string Village { get; set; }
        public string Group { get; set; }
        public byte[] image { get; set; }
        public string SPCNum1 { get; set; }
        public string SPCNum2 { get; set; }
        public string SPAddress { get; set; }
        public string SPName { get; set; }
        public string FathName { get; set; }
        public string MothName { get; set; }
        public string Fam1 { get; set; }
        public string Fam2 { get; set; }
        public string Fam3 { get; set; }
        public string Fam4 { get; set; }
        public string Fam5 { get; set; }
        public string Fam6 { get; set; }
        public string Fam7 { get; set; }
        public string Fam8 { get; set; } 
        public string FamCond { get; set; }
        public string FamNotes { get; set; }
        public string Status { get; set; }
        public DateTime EntryDate { get; set; }
        public DateTime DOA { get; set; }
 
        public string FathOccu { get; set; }
        public string MothOccu { get; set; }
 

 
 
    }

 <blockquote class="FQ"><div class="FQA">Quote:</div>       public class InformationDbContext : DbContext
        {
            public DbSet<information> Information { get; set; }
        }
 
        public class InfoDBContext : DbContext
        {
