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

我有一个使用WCF服务与数据库通信的Silverlight 3.0应用程序,当我从服务方法返回大量数据时,我得到Service Not Found错误.我相信它的解决方案是简单地更新maxItemsInObjectGraph属性,但我正在以编程方式创建服务客户端,但无法找到设置此属性的位置.这就是我现在正在做的事情：

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")));

解决方法

它没有在绑定中定义,而是在服务行为中定义.

在Silveright中,maxItemsInObjectGraph默认为int.MaxValue.

这是一篇关于如何为.NET应用程序更改它的文章,但不是Silverlight：Programattically setting the MaxItemsInObjectGraph property in client

一段代码：

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;
}
