我正在尝试将来自多个表的数据显示到单个视图中，使用户能够根据需要添加，更改或删除数据。到目前为止，我甚至无法使用一个单独的视图来使用控制器，更不用说具有一个视图的多个控制器了。我使用的是MVC 5，VS 2013（C＃），数据库托管在另一台计算机上。
这是家庭控制器：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Vivace.Models;
namespace Vivace.Controllers
{
public class HomeController : Controller
{
public VivaceContext db = new VivaceContext();
List<Distributor> list = new List<Distributor>();
public ActionResult Index()
{
// var ist = db.Distributors.FirstOrDefault(x => x.Address == "").Orders.ToList();
// var i = db.Distributors.Where(x => x.Address == "").ToList();
return View();
}
public ActionResult About()
{
//ViewBag.Message = "Your application description page.";z
return View();
}
public ActionResult Contact()
{
//ViewBag.Message = "Your contact page.";
return View();
}
public ActionResult Ordering()
{
//ViewBag.Message = "Place your orders."
return View();
}
public ActionResult Inventory(string Categories)
{
//ViewBag.Message = "View items currently in stock.";
var categoriesModel = new Category
{
CatName = Categories,
Items = this.db.Items.ToList()
};
return this.View(categoriesModel);
}
public ActionResult Item()
{
return View();
}
}
}
这是项目控制器（项目是我想要显示数据的一个表的名称）：
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using Vivace.Models;
namespace Vivace.Controllers
{
public class ItemController : Controller
{
private VivaceContext db = new VivaceContext();
// GET: /Item/
public ActionResult Index()
{
var items = db.Items.Include(i => i.Category1).Include(i => i.Department1).Include(i => i.Distributor1);
return View(items.ToList());
}
// GET: /Item/Details/5
public ActionResult Details(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Item item = db.Items.Find(id);
if (item == null)
{
return HttpNotFound();
}
return View(item);
}
// GET: /Item/Create
public ActionResult Create()
{
ViewBag.Category = new SelectList(db.Categories, "CatNumber", "CatName");
ViewBag.Department = new SelectList(db.Departments, "DeptNum", "DeptName");
ViewBag.Distributor = new SelectList(db.Distributors, "DistributorNumber", "DistributorName");
return View();
}
// POST: /Item/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include="ItemNumber,UPC,ItemName,Category,Department,Price,Cost,MarkUp,OnHand,InWherehouse,OnOrder,OnFeature,ShelfCap,Distributor")] Item item)
{
if (ModelState.IsValid)
{
db.Items.Add(item);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.Category = new SelectList(db.Categories, "CatNumber", "CatName", item.Category);
ViewBag.Department = new SelectList(db.Departments, "DeptNum", "DeptName", item.Department);
ViewBag.Distributor = new SelectList(db.Distributors, "DistributorNumber", "DistributorName", item.Distributor);
return View(item);
}
// GET: /Item/Edit/5
public ActionResult Edit(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Item item = db.Items.Find(id);
if (item == null)
{
return HttpNotFound();
}
ViewBag.Category = new SelectList(db.Categories, "CatNumber", "CatName", item.Category);
ViewBag.Department = new SelectList(db.Departments, "DeptNum", "DeptName", item.Department);
ViewBag.Distributor = new SelectList(db.Distributors, "DistributorNumber", "DistributorName", item.Distributor);
return View(item);
}
// POST: /Item/Edit/5
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include="ItemNumber,UPC,ItemName,Category,Department,Price,Cost,MarkUp,OnHand,InWherehouse,OnOrder,OnFeature,ShelfCap,Distributor")] Item item)
{
if (ModelState.IsValid)
{
db.Entry(item).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.Category = new SelectList(db.Categories, "CatNumber", "CatName", item.Category);
ViewBag.Department = new SelectList(db.Departments, "DeptNum", "DeptName", item.Department);
ViewBag.Distributor = new SelectList(db.Distributors, "DistributorNumber", "DistributorName", item.Distributor);
return View(item);
}
// GET: /Item/Delete/5
public ActionResult Delete(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Item item = db.Items.Find(id);
if (item == null)
{
return HttpNotFound();
}
return View(item);
}
// POST: /Item/Delete/5
[HttpPost, ActionName("Delete")]
[ValidateAntiForgeryToken]
public ActionResult DeleteConfirmed(int id)
{
Item item = db.Items.Find(id);
db.Items.Remove(item);
db.SaveChanges();
return RedirectToAction("Index");
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
}
}
这是我想要显示数据的视图（文本框是为了允许提交新数据，即订单，或搜索以前的订单）：
@{
ViewBag.Title = "Ordering";<input id="Text1" type="text" />
}
<h2>Ordering</h2>
<fieldset>
<legend>Order Information</legend>
<form>
<p><label for="distributor">Distributor:</label>
<input type="text" name="distributor" value="@Request.Form["distributor"]" /></p>
<p><label for="product">Product:</label>
<input type="text" name="product" value="@Request.Form["product"]"/></p>
<p><label for="quantity">Quantity:</label>
<input type="number" name="quantity" value="@Request.Form["quantity"]"/></p>
<p><label for="date">Date:</label>
<input type="date" name="date" value="@Request.Form["date"]"/></p>
<input type="submit" value="Place Order">
</form>
<legend>Order History</legend>
<label>Search by:</label>
<form>
<p>
<label for="distributorHist">Distributor:</label>
<input type="text" name="distributorHist" value="@Request.Form["distributorHist"]" /></p>
<p>
<label for="productHist">Product:</label>
<input type="text" name="productHist" value="@Request.Form["productHist"]" /></p>
<p>
<label for="dateHist">Date:</label>
<input type="date" name="dateHist" value="@Request.Form["dateHist"]" /></p>
<input type="submit" value="View History">
</form>
</fieldset>
我有什么遗失的东西吗？
编辑： 我想我学会了如何实现局部视图，但现在我遇到了一个新错误：
Server Error in '/' Application.

我将这段代码从名为Index的Item View移到了Ordering View：
<td>
@Html.DisplayFor(modelItem => item.UPC)
</td>
<td>
@Html.DisplayFor(modelItem => item.ItemName)
</td>
<td>
@Html.DisplayFor(modelItem => item.Price)
</td>
<td>
@Html.DisplayFor(modelItem => item.Cost)
</td>
<td>
@Html.DisplayFor(modelItem => item.MarkUp)
</td>
<td>
@Html.DisplayFor(modelItem => item.OnHand)
</td>
<td>
@Html.DisplayFor(modelItem => item.InWherehouse)
</td>
<td>
@Html.DisplayFor(modelItem => item.OnOrder)
</td>
<td>
@Html.DisplayFor(modelItem => item.OnFeature)
</td>
<td>
@Html.DisplayFor(modelItem => item.ShelfCap)
</td>
<td>
@Html.DisplayFor(modelItem => item.Category1.CatName)
</td>
<td>
@Html.DisplayFor(modelItem => item.Department1.DeptName)
</td>
<td>
@Html.DisplayFor(modelItem => item.Distributor1.DistributorName)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id = item.ItemNumber }) |
@Html.ActionLink("Details", "Details", new { id = item.ItemNumber }) |
@Html.ActionLink("Delete", "Delete", new { id = item.ItemNumber })
</td>
我迷路了。

将公共视图设为部分视图。
为每个控制器的每个视图都有一个单独的cshtml，但只是让它们加载局部视图。

您可以使用ViewBag存储一个表的数据并将其传递给View，同时将其他表数据作为模型进行查看。但最好的方法是为视图创建一个ViewModel类，然后将该ViewModel类映射到Model（域）类。使用automapper将ViewModel映射到Model类。
