在Silverlight中是使用ServiceReferences.ClientConfig文件来保存和查看WCF服务的相对信息的
而ServiceReferences.ClientConfig又是包含在.xap文件中的
这样就导致如果您的Silverlight工程有用到WCF服务就需要在每次部署到不同网站的时候重新更改下WCF的配置并重新编译
而且这个重新配置的过程又往往可能需要Visual Studio 2008的帮助来重新链接WCF服务
而且对于有些部署的服务器就可能非常不现实了（有的服务器要求系统干净，不允许安装其他软件）
那么怎么办呢？
首先让我们来创建一个含有WCF Service的Silverlight工程
并在Web工程中添加一个Silverlight-enabled WCF Service如下
并在其中加入如下代码用于存储产品信息（包括Name名字、Description描述、Price价格）：
1: [DataContract] 2: public class ProductInfo 3: { 4: [DataMember] 5: public string Name; 6: 7: [DataMember] 8: public double Price; 9: 10: [DataMember] 11: public string Description; 12: }而其OperateContract为
1: [ServiceContract(Namespace = "")] 2: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 3: public class ProductService 4: { 5: [OperationContract] 6: public List<ProductInfo> RetreiveData() 7: { 8: List<ProductInfo> products=new List<ProductInfo>(); 9: for (int i = 0; i < 8; i++) 10: { 11: products.Add(new ProductInfo() 12: { 13: Name = "Product " + (i + 1), 14: Price = 30.5*(i+1), 15: Description = "Product "+(i+1)+" for test" 16: } 17: ); 18: } 19: // Add your operation implementation here 20: return products; 21: } 22: }用来以WCF Service的形式将数据库中的数据（这里为方便期间用了伪数据）传给Silverlight客户端
首先给Silverlight工程添加Service References
我们在Silverlight客户端这边以ListBox的形式呈现出来，定义如下（Page.xaml文件中）
1: <ListBox x:Name="ProductLBCtl" HorizontalAlignment="Center" VerticalAlignment="Top" Background="Transparent" BorderThickness="0"> 2: <ListBox.ItemTemplate> 3: <DataTemplate> 4: <StackPanel Orientation="Horizontal"> 5: <ContentPresenter Content="{Binding Name}" Margin="10,0"/> 6: <ContentPresenter Content="{Binding Description}" Margin="10,0"/> 7: <ContentPresenter Content="{Binding Price}" Margin="10,0"/> 8: </StackPanel> 9: </DataTemplate> 10: </ListBox.ItemTemplate> 11: </ListBox>获取WCF Service的数据信息如下（Page.xaml.cs中）
1: public Page() 2: { 3: InitializeComponent(); 4: this.Loaded += new RoutedEventHandler(Page_Loaded); 5: } 6: 7: void Page_Loaded(object sender, RoutedEventArgs e) 8: { 9: ProductServiceClient client=new ProductServiceClient(); 10: this.Cursor = Cursors.Hand; 11: client.RetreiveDataAsync(); 12: client.RetreiveDataCompleted += (sender2, e2) => 13: { 14: if (e2.Cancelled == false && e2.Error == null) 15: { 16: ObservableCollection<ProductInfo> products = e2.Result; 17: this.ProductLBCtl.ItemsSource = products; 18: this.Cursor = Cursors.Arrow; 19: } 20: }; 21: }这样我们就可以获得到WCF Service传过来的数据了
部署时由于WCF Service的部署地址不同，将需要我们重新索引，并编译这个程序，非常繁琐
你可以采用如下的动态配置的方式一举解决这个问题：
删除ServiceReferences.ClientConfig文件,并在Silverlight 工程下添加一个类文件(Class File)ServiceUtil.cs如下
1: public static ProductServiceClient GetDynamicClient() 2: { 3: BasicHttpBinding binding = new BasicHttpBinding( 4: Application.Current.Host.Source.Scheme.Equals("https", StringComparison.InvariantCultureIgnoreCase) 5: ? BasicHttpSecurityMode.Transport : BasicHttpSecurityMode.None); 6: binding.MaxReceivedMessageSize = int.MaxValue; 7: binding.MaxBufferSize = int.MaxValue; 8: return new ProductServiceClient(binding, new EndpointAddress( 9: new Uri(Application.Current.Host.Source, "../ProductService.svc"))); 10: }上述就是通过动态的形式获取得到ProductService了
修改Page.xaml.cs文件如下
1: void Page_Loaded(object sender, RoutedEventArgs e) 2: { 3: ProductServiceClient client = ServiceUtil.GetDynamicClient();//动态获取ProductServiceClient 4: this.Cursor = Cursors.Hand; 5: client.RetreiveDataAsync(); 6: client.RetreiveDataCompleted += (sender2, e2) => 7: { 8: if (e2.Cancelled == false && e2.Error == null) 9: { 10: ObservableCollection<ProductInfo> products = e2.Result; 11: this.ProductLBCtl.ItemsSource = products; 12: this.Cursor = Cursors.Arrow; 13: } 14: }; 15: }这样大家就可以在不用修改的情况下非常便捷的部署到IIS或者Apache上了
