Question

我有3个表格如下：工作：IdJob，描述，......

JobSkill：IdSkill，Id_Job，Title，Description，Level ...

JobRequirments：IdReq，Id_Job，Title，Description ...

（填写如下数据： 1，Job1，Title1 2，Job2，Title 2 ///// 1,1，Skill1Job1 2,1，Skill2Job1 3,2，Skill1Job2 /// 1,1，Req1Job1 2,1，Req2Job1 3,2，Req1Job2 4,2，Req2Job2 ///等等

在视图中，我按如下方式显示Jobs表中的所有作业：

@model IEnumerable<JobShop.Jobs>

@{
    ViewBag.Title = "Jobs Listing Index";
}

<div class="title-lines">
    <h3 class="mt0">Available Jobs Listing</h3>
</div>
@if (Model.Count() > 0)
{
    <div>
    @{int i = 1;
    foreach (var item in Model)
    {
        <div class="bordered @(i++ % 2 == 0 ? "highlighted" : "")">
            <p>@item.IdJob</p>
            <p>@item.Titlu</p>
            <p>@item.DateAdd</p>
            <div class="thumb">
                <img src="@item.ImageSRC" />
            </div>
            <p class="">@item.Description</p>
            <p class="">@item.Content</p>
            <p class="">@item.Demand</p>
            <p>@item.Address</p> 
            <!--Here I want another div for JobSkills
            <div>
            foreach (var item1 in WhatModel1)
            {
            <div class="JobSkill">
            //Skill(s)
            <p>@item1.Id_Job</p>
            <p>@item1.Title</p>
            <p>@item1.Level</p>
            </div>
            }
            </div>
            -->
            <!--Here I want another div for JobsRequirments
            <div>
            foreach (var item2 in WhatModel2)
            {
            <div class="JobReq">
            //Requirment(s)
            <p>@item2.Id_Job </p>           
            <p>@item2.Requirment</p>
            </div>
            -->
            }
            </div>
        </div>
    }
    }
    </div>
}
else
{<p style="color: red">Sorry ! No record(s) found.</p>}

如何在主foreach循环的每次迭代中从其他2个表中提取数据？

我也有模特：

namespace JobShop
{
    using System;
    using System.Collections.Generic;

    public partial class Jobs
    {
        public Jobs()
        {
            this.JobRequirements = new HashSet<JobRequirements>();
            this.JobSkills = new HashSet<JobSkills>();
        }

        public int IdJob { get; set; }
        public Nullable<int> IdWho { get; set; }
        public string User { get; set; }
        public Nullable<System.DateTime> DateAdd { get; set; }
        public string ImageSRC { get; set; }
        public string Titlu { get; set; }
        public string WhereWhat { get; set; }
        public string Description { get; set; }
        public string Content { get; set; }
        public string Solicitare { get; set; }
        public Nullable<System.DateTime> DateStart { get; set; }
        public Nullable<System.DateTime> DateEnd { get; set; }
        public string Orar { get; set; }
        public string Address { get; set; }
        public Nullable<double> Latitudine { get; set; }
        public Nullable<double> Longitudine { get; set; }
        public string ZIP { get; set; }

        public virtual AspNetUsers AspNetUsers { get; set; }
        public virtual ICollection<JobRequirements> JobRequirements { get; set; }
        public virtual ICollection<JobSkills> JobSkills { get; set; }
    }
}

和控制器的相关部分：

namespace JobShop
{
    public class JobsController : Controller
    {
        private JobShopEntities db = new JobShopEntities();

        // GET: Jobs
        public ActionResult Index(string sortOrder, string currentFilter, string searchString, int? page)
        {
            //stuff for paging, searching and sorting
            ViewBag.CurrentSort = sortOrder;
            ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
            ViewBag.DateSortParm = sortOrder == "Date" ? "date_desc" : "Date";

            if (searchString != null)
            {
                page = 1;
            }
            else
            {
                searchString = currentFilter;
            }

            ViewBag.CurrentFilter = searchString;
            //
            var jobs = db.Jobs.Include(j => j.AspNetUsers);
            //Some search stuff
            if (!String.IsNullOrEmpty(searchString))
            {
                jobs = jobs.Where(s => s.Titlu.Contains(searchString)
                                   || s.Description.Contains(searchString));
            }
            //
            switch (sortOrder)
            {
                case "name_desc":
                    jobs = jobs.OrderByDescending(s => s.Titlu);
                    break;
                case "Date":
                    jobs = jobs.OrderBy(s => s.DateAdd);
                    break;
                case "date_desc":
                    jobs = jobs.OrderByDescending(s => s.DateAdd);
                    break;
                default:
                    //jobs = jobs.OrderBy(s => s.Titlu);
                    jobs = jobs.OrderBy(s => s.DateAdd);
                    break;

            }

            //
            int pageSize = 5;
            int pageNumber = (page ?? 1);
            return View(jobs.ToPagedList(pageNumber, pageSize));
            //return View(jobs.ToList());
        }

Answer 1

该模型是IEnumerable<JobShop.Jobs>的实例。

foreach (var item in Model)

每个项目都是JobShop.Jobs的实例。因此，您可以像访问任何常规C＃类一样访问JobShop.Jobs的属性。

foreach(var jobRequirements in item.JobRequirements)

和

foreach(var jobSkills in item.JobSkills)

使用razor在mvc中的同一视图中显示多个表的结果
