如何从Silverlight应用程序以编程方式设置maxItemsInObjectGraph属性?

BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None)
{
    MaxReceivedMessageSize = int.MaxValue,                  
    MaxBufferSize = int.MaxValue
};                        

MyService.MyServiceServiceClient client = new MyService.MyServiceProxyServiceClient(binding, new EndpointAddress(new Uri(Application.Current.Host.Source, "../MyService.svc")));

它不是在绑定中定义的,而是在服务行为中定义的。

在Silverlight中,maxItemsInObjectGraph默认为int.MaxValue。

以下是一篇关于如何为.NET应用程序(而不是Silverlight)更改它的文章: Programattically setting the MaxItemsInObjectGraph property in client

protected ISecurityAdministrationService GetSecAdminClient()
{
     ChannelFactory<ISecurityAdministrationService> factory = new    ChannelFactory<ISecurityAdministrationService>(wsSecAdminBinding, SecAdminEndpointAddress);
     foreach (OperationDescription op in factory.Endpoint.Contract.Operations)
     {
       DataContractSerializerOperationBehavior dataContractBehavior =op.Behaviors.Find<DataContractSerializerOperationBehavior>() as DataContractSerializerOperationBehavior;
       if (dataContractBehavior != null)
       {
             dataContractBehavior.MaxItemsInObjectGraph = 2147483647;
       }
     }
    ISecurityAdministrationService client = factory.CreateChannel();
    return client;
}

下面是我在继承自的客户机对象中使用的函数

System.ServiceModel.ClientBase(Of IServiceName)

该方法的目的是通过编程为每个操作设置MaxItemsInObjectGraph值。这让我有更复杂的结构。

    Private Sub IncreaseObjectCount()
        For Each op As System.ServiceModel.Description.OperationDescription In Me.Endpoint.Contract.Operations
            For Each dscob As System.ServiceModel.Description.DataContractSerializerOperationBehavior In op.Behaviors.FindAll(Of System.ServiceModel.Description.DataContractSerializerOperationBehavior)()
                dcsob.MaxItemsInObjectGraph = Integer.MaxValue
            Next dcsob
        Next op
    End Sub

在WCF服务中为每个端点更改maxItemsInObjectGraph,在Silverlight中更改它意味着客户端将能够支持该行为,但服务也必须支持它。

在您的服务中更改它之后,重新生成代理/更新web服务,您将获得一个新的ServiceReference.config,其中将包含新的maxItemsInObjectGraph值
