如何使用Silverlight+WCF Ria Services Class Library 类库

1. 打开VS2010新建一个项目，类型选择Silverlight Application

2. 第二步勾上“Enable WCF Ria Service”，会给你自动加上引用一些类库

3. 拖一个DataGrid控件到MainPage.xaml里面，设置属性 AutoGenerateColumns="True"

4. 添加数据模型 DomainLayer，这里用Entity Framework来做数据模型，自动获得ORM和持久化。方法是右键点击你的solution，添加一个class library项目，然后在这个项目中添加新项：Ado.NET Entity Data Model

5. 会要求连接到数据库，选择 Generate from database，选择Connection String，选择表和视图等，然后生成edmx。

6. 生成数据模型以后，build solution

7. 右键点击你的solution，添加新的项目，类型选择 WCF Ria Service Class Library

8. 会自动生成两个项目 RIAServicesLibrary1和RIAServicesLibrary1.web，前者是客户端的Silverlight项目，后者是服务器端的项目，两者有共享代码。

9. 添加引用：SilverlightApplication1项目添加对RIAServicesLibrary1项目的引用，SilverlightApplication1.Web添加对RIAServicesLibrary1.Web的引用。

10. RIAServicesLibrary1.Web项目添加对数据模型 DomainLayer项目（第4步添加的项目）的引用。

11. RIAServicesLibrary1.Web项目添加新项：Domain Service Class

12. 会出来一个界面选择DataContext，选择你需要的即可。

13. 生成

14. RIAServicesLibrary1项目可以按需添加调用RIAServicesLibrary1.Web的Domain service，例如：

调用DomainServices

 1 using System;
 2  using System.Collections.Generic;
 3  using System.Net;
 4  using System.Windows;
 5  using System.Windows.Controls;
 6  using System.Windows.Documents;
 7  using System.Windows.Ink;
 8  using System.Windows.Input;
 9  using System.Windows.Media;
10  using System.Windows.Media.Animation;
11  using System.Windows.Shapes;
12 
13 using RIAServicesLibrary1.Web;
14 using System.ServiceModel.DomainServices.Client;
15 using DataModel;
16 
17 namespace RIAServicesLibrary1
18 {
19     public class TestClass
20     {
21         public IEnumerable<Company> GetCompanyList()
22         {
23             DomainService1 s = new DomainService1();
24             LoadOperation<Company> loadOp = s.Load(s.GetCompaniesQuery());
25             return loadOp.Entities;
26         }
27     }
28 }

15. 前台调用RIAServicesLibrary1的代码并显示，例如：

MainPage.xaml.cs

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Net;
 5 using System.Windows;
 6 using System.Windows.Controls;
 7 using System.Windows.Documents;
 8 using System.Windows.Input;
 9 using System.Windows.Media;
10 using System.Windows.Media.Animation;
11 using System.Windows.Shapes;
12 using RIAServicesLibrary1;
13 
14 namespace RiaClassLibraryTest
15 {
16     public partial class MainPage : UserControl
17     {
18         public MainPage()
19         {
20             InitializeComponent();
21 
22             TestClass c = new TestClass();
23             dataGrid1.ItemsSource = c.GetCompanyList();
24         }
25     }
26 }

16. 调整项目结构，按Client，Server进行组合，例如：

17. 修改Web.config，否则会遇到一大堆错误（遇到错误请用Fiddler进行调试）

Web.config

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <!--

 6 <configuration>
 7   <system.webServer>
 8     <modules runAllManagedModulesForAllRequests="true">
 9       <add name="DomainServiceModule" preCondition="managedHandler"
10         type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
11     </modules>
12     <validation validateIntegratedModeConfiguration="false" />
13   </system.webServer>
14   <system.web>
15     <httpModules>
16       <add name="DomainServiceModule" type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
17     </httpModules>
18     <compilation debug="true" targetFramework="4.0">
19       <assemblies>
20         <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
21       </assemblies>
22     </compilation>
23   </system.web>
24   <connectionStrings>
25     <add name="MyEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.1.345;initial catalog=Northwind;persist security info=True;user id=sa;password=******;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
26   </connectionStrings>
27   <system.serviceModel>
28     <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
29       multipleSiteBindingsEnabled="true" />
30   </system.serviceModel>
31 </configuration>

18. 运行。（注：System.ServiceModel.DomainServices.Client.dll 位于 C:\Program Files\Microsoft SDKs\RIA Services\v1.0\Libraries\Silverlight 目录下。）
