在ASP.NET MVC3 中使用OData

1. 新建一个asp.net mvc3 应用程序项目
2. 添加服务引用
   
3. 输入地址：http://services.odata.org/Northwind/Northwind.svc/ 转到并添加NorthwindService命名空间
   
4. 新建控制器
   
5. 按F6进行编译
6. 添加强类型分部视图ProductList
   
7. 替换Views/Product/ProductList.cshtml代码
   

   @model IEnumerable<ODataMvcApplication.NorthwindService.Product>
   
   <table>
       <tr>
           <th>
               ProductName
           </th>
           <th>
               SupplierID
           </th>
           <th>
               CategoryID
           </th>
           <th>
               QuantityPerUnit
           </th>
           <th>
               UnitPrice
           </th>
           <th>
               UnitsInStock
           </th>
           <th>
               UnitsOnOrder
           </th>
           <th>
               ReorderLevel
           </th>
           <th>
               Discontinued
           </th>
       </tr>
   
   @foreach (var item in Model) {
       <tr>
           <td>
               @Html.DisplayFor(modelItem => item.ProductName)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.SupplierID)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.CategoryID)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.QuantityPerUnit)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.UnitPrice)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.UnitsInStock)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.UnitsOnOrder)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.ReorderLevel)
           </td>
           <td>
               @Html.DisplayFor(modelItem => item.Discontinued)
           </td>
       </tr>
   }
   
   </table>

8. 替换Controllers/ProductController.cs代码

   using ODataMvcApplication.NorthwindService;
   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Web;
   using System.Web.Mvc;
   
   namespace ODataMvcApplication.Controllers
   {
       public class ProductController : Controller
       {
           public ActionResult Index()
           {
               return View();
           }
   
           public PartialViewResult Products(int id)
           {
               var context = new NorthwindEntities(new Uri("http://services.odata.org/Northwind/Northwind.svc/"));
               var products = from product in context.Products where product.CategoryID == id select product; return PartialView("ProductList", products.ToList());
           }
   
           static public List<Category> Categories() { var context = new NorthwindEntities(new Uri("http://services.odata.org/Northwind/Northwind.svc/")); return context.Categories.ToList(); }
       }
   
   
   }

9. 添加Index视图
   
10. 替换Views/Product/Index.cshtml代码

    @{
        Layout = null;
    }
    <script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")"></script>
    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("#category").change(function () { loadView($(this).val()); }); loadView("1");
        });
        function loadView(cat)
        {
            $("#content").html("加载中。。。。");
            $.get('@Url.RouteUrl("default", new { controller = "Product", action = "Products" })', { id: cat }, function (data) {
                $("#content").html(data);
            });
        }
    
    </script>
    <div>
        <h1>Products</h1>
        <div>
            <div>Category:</div>
            @Html.DropDownList("category", ODataMvcApplication.Controllers.ProductController.Categories().Select(c => new SelectListItem { Text = c.CategoryName, Value = c.CategoryID.ToString() }))    </div>
        <hr />
        <div id="content">加载中....</div>
    </div>
