Eccezione: il numero massimo di elementi che possono essere serializzati o deserializzati in un oggetto grafico è '65536'

Question

Ho esaminato altri messaggi, ma non ho trovato la soluzione al mio problema.

Perché ho ancora un'eccezione:

The formatter threw an exception while trying to deserialize the message: 
There was an error while trying to deserialize parameter http://tempuri.org/:GetData. 
The InnerException message was 'Maximum number of items that can be serialized or deserialized in an object graph is '65536'. 
Change the object graph or increase the MaxItemsInObjectGraph quota. '. 

Is sembra ignorare <dataContractSerializer maxItemsInObjectGraph="2147483647"/> in entrambi i file App.config . Perché?

Answer 1

Ho risolto questo problema aggiungendo il comportamento nel codice C#.

client.Endpoint.Behaviors.Remove(typeof(CallbackBehaviorAttribute)); 
client.Endpoint.Behaviors.Add(new CallbackBehaviorAttribute() { MaxItemsInObjectGraph = 2147483647 }); 

problema probabilmente è dovuta a causa di utilizzare ServiceClient costruttore con InstanceContext, Binding e EndpointAddress così il comportamento da app.config viene ignorato.

Answer 2

Al client, vedere le 3 linee marcate ****:

<client> 
     <endpoint address="http://.../Design_Time_Addresses/Service2/" 
****  behaviorConfiguration="foo" 
      binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService2" 
      contract="Service2Reference.IService2" 
      name="WSHttpBinding_IService2"> 
      <identity> 
       <dns value="localhost" /> 
      </identity> 
     </endpoint> 
     <endpoint address="net.tcp://.../Design_Time_Addresses/Service1/" 
****  behaviorConfiguration="foo" 
      binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IService1" 
      contract="Service1Reference.IService1" name="NetTcpBinding_IService1"> 
      <identity> 
       <dns value="localhost" /> 
      </identity> 
     </endpoint> 
    </client> 
    <behaviors> 
    <endpointBehaviors> 
**** <behavior name="foo"> 
     <dataContractSerializer maxItemsInObjectGraph="2147483647"/> 
     </behavior> 
    </endpointBehaviors> 
    </behaviors> 

Answer 3

aggiungere alla configurazione

<behaviors> 
    <endpointBehaviors> 
     <behavior name="Behaviors.EndpointBehavior"> 
      <dataContractSerializer maxItemsInObjectGraph="2147483647" /> 
     </behavior> 
    </endpointBehaviors> 
</behaviors 

Quindi definire il vostro cliente con un comportamento

<client> 
    <endpoint address=http://localhost:9997/Services/MyService 
     behaviorConfiguration="Behaviors.EndpointBehavior" 
     binding="wsHttpBinding" bindingConfiguration="WSHTTPBinding.Configuration.Client" 
     contract="IAppointments" name="Client.EndpointConfiguration" /> 
</client> 

o di farlo in codice

foreach (var operation in channelFactory.Endpoint.Contract.Operations) 
{ 
    var behavior = operation.Behaviors.Find() as DataContractSerializerOperationBehavior; 
    if (behavior != null) 
    { 
     behavior.MaxItemsInObjectGraph = 2147483647;  
    } 
}

penso che si hanno per decorare la definizione lato server e l'endpoint client.
