Exception: le nombre maximal d'éléments qui peuvent être sérialisés ou désérialisés dans un graphique d'objet est '65536'

Question

J'ai regardé d'autres articles, mais je n'ai pas trouvé de solution à mon problème.

Pourquoi je reçois encore exception:

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 semble ignorer <dataContractSerializer maxItemsInObjectGraph="2147483647"/> dans les deux App.config fichiers . Pourquoi?

Answer 1

J'ai résolu ce problème en ajoutant un comportement en code C#.

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

problème est probablement dû au fait que l'utilisation constructeur ServiceClient avec InstanceContext, Binding et EndpointAddress si le comportement de app.config est ignoré.

Answer 2

Au client, voir les 3 lignes marquées ****:

<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

Ajouter à la configuration

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

Définissez ensuite votre client avec le comportement

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

Ou le faire en code derrière

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

Je pense que vous devez décorer la définition du côté serveur et le point de terminaison client ainsi.
