Silverlight 调用 RIA Service

今天给一个Silverlight的项目做后台，发现了几个选择，WCF RIA Service，Web Service，还有Ado data service，选了第一个，微软的东西名字一个一个，真是麻烦。

 

上网找了些资料，大部分都是help里那个例子的翻译，汗一个。微软的例子总是用他自己那些wizard，而且搭上一个adonet的datasource，看得我非常不爽。因为我nhibernate层已经写完了。

 

然后发现RIA服务是异步的，建立一个Silverlight项目后会生成一个sl的app个sl的web，

往里面加一个ria服务的class library项目，又多了两个项目，ria 类库项目和ria web项目。

然后SL的web应用ria的web，sl的app引用ria的类库。依赖关系就建立好了。

 

结构如下。

 

 

 

 

RIA类库的行为比较怪异，为了给客户端用，可以发现上图有一个Generated_Code的文件夹，

里面是ria web里生成的代码。

 

我们做的事情都在DomainService1这个文件里，做一个方法，编译一下，会生成一些相应的代码给SL用。

DomainService1的代码如下。

namespace RIAServicesLibrary1.Web { using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Collections.Generic; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.ComponentModel; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.ComponentModel.DataAnnotations; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Linq; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.ServiceModel.<a href="https://www.jb51.cc/tag/domainservices/" target="_blank" class="keywords">domainservices</a>.Hosting; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.ServiceModel.<a href="https://www.jb51.cc/tag/domainservices/" target="_blank" class="keywords">domainservices</a>.Server; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Runtime.Serialization; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Collections; // T<a href="https://www.jb51.cc/tag/odo/" target="_blank" class="keywords">odo</a>: Create methods containing your application logic. [EnableClientAccess()] public class DomainService1 : DomainService { public IQueryable<Customer> GetCustomers() { List<Customer> customerList = new List<Customer>(); customerList.Add(new Customer() { ID = "1",Name = "zbo" }); return customerList.AsQueryable(); } [Insert] public void AddCustomer(Customer customer) { var some = customer; } [Update] public void UpdateCustomer(Customer customer) { var some = customer; } [Query] public IEnumerable<Customer> QueryCustomer() { List<Customer> customerList = new List<Customer>(); customerList.Add(new Customer() { ID = "1",Name = "zbo" }); return customerList.AsEnumerable(); } } }

 

SL调用的代码如下

using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Collections.Generic; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Linq; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Net; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.ServiceModel.<a href="https://www.jb51.cc/tag/domainservices/" target="_blank" class="keywords">domainservices</a>.Client; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Controls; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Documents; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Input; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Media; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Media.Animation; using Sy<a href="https://www.jb51.cc/tag/stem/" target="_blank" class="keywords">stem</a>.Windows.Shapes; using RIAServicesLibrary1.Web; namespace SilverlightApplication { public partial class MainPage : UserControl { private DomainService1 TestWork = new DomainService1(); public MainPage() { InitializeComponent(); DomainService1 service = new DomainService1(); EntitySet<Customer> entitySet = service.Customers; } private void button1_Click(object sender,RoutedEventArgs e) { //TestWork.Load(TestWork.GetCustomersQuery()).Completed += new EventHandler(invokeOperation_Completed); TestWork.Load(TestWork.QueryCustomerQuery()).Completed += new EventHandler(MainPage_Completed); } private void MainPage_Completed(object sender,EventArgs e) { var some = TestWork.Customers; some.F<a href="https://www.jb51.cc/tag/irs/" target="_blank" class="keywords">irs</a>t().Name = "changed"; } //private void invokeOperation_Completed(object sender,EventArgs e) //{ // string value = (sender as LoadOperation<Customer>).Entities.F<a href="https://www.jb51.cc/tag/irs/" target="_blank" class="keywords">irs</a>t().Name; // this.text<a href="https://www.jb51.cc/tag/Box/" target="_blank" class="keywords">Box</a>1.Text = value; // (sender as LoadOperation<Customer>).Entities.F<a href="https://www.jb51.cc/tag/irs/" target="_blank" class="keywords">irs</a>t().Name = "changed"; //} private void button2_Click(object sender,RoutedEventArgs e) { TestWork.Customers.Add(new Customer() {ID = "2",Name = "ama"}); TestWork.Customers.Add(new Customer() {ID = "3",Name = "sor"}); TestWork.SubmitChanges(); } private void button3_Click(object sender,RoutedEventArgs e) { TestWork.SubmitChanges(); } } }

 

SL调用里一个方法被我注释掉了。

因为今天发现得到model的时候必须有【query】这个标记。

貌似没有这个标记，可以得到model，但是修改后commit回去的时候不会调用update的方法。

 

今天是第一天做Silverlight，希望这几天能有跟多发现。
