Esempio

Nell'esempio seguente, l'oggetto DataContractSerializerOperationBehavior viene individuato nella raccolta dei comportamenti di un'operazione e le proprietà MaxItemsInObjectGraph e IgnoreExtensionDataObject vengono reimpostate.

private void DataContractBehavior()
{
    WSHttpBinding b = new WSHttpBinding(SecurityMode.Message);
    Uri baseAddress = new Uri("http://localhost:1066/calculator");
    ServiceHost sh = new ServiceHost(typeof(Calculator), baseAddress);
    sh.AddServiceEndpoint(typeof(ICalculator), b, "");

    // Find the ContractDescription of the operation to find.
    ContractDescription cd = sh.Description.Endpoints[0].Contract;
    OperationDescription myOperationDescription = cd.Operations.Find("Add");

    // Find the serializer behavior.
    DataContractSerializerOperationBehavior serializerBehavior =
        myOperationDescription.Behaviors.
           Find<DataContractSerializerOperationBehavior>();

    // If the serializer is not found, create one and add it.
    if (serializerBehavior == null)
    {
        serializerBehavior = new DataContractSerializerOperationBehavior(myOperationDescription);
        myOperationDescription.Behaviors.Add(serializerBehavior);
    }

    // Change the settings of the behavior.
    serializerBehavior.MaxItemsInObjectGraph = 10000;
    serializerBehavior.IgnoreExtensionDataObject = true;

    sh.Open();
    Console.WriteLine("Listening");
    Console.ReadLine();
}

Private Sub DataContractBehavior() 
    Dim b As New WSHttpBinding(SecurityMode.Message)
    Dim baseAddress As New Uri("http://localhost:1066/calculator")
    Dim sh As New ServiceHost(GetType(Calculator), baseAddress)
    sh.AddServiceEndpoint(GetType(ICalculator), b, "")
    
    ' Find the ContractDescription of the operation to find.
    Dim cd As ContractDescription = sh.Description.Endpoints(0).Contract
    Dim myOperationDescription As OperationDescription = cd.Operations.Find("Add")
    
    ' Find the serializer behavior.
    Dim serializerBehavior As DataContractSerializerOperationBehavior = _
    myOperationDescription.Behaviors.Find _
    (Of DataContractSerializerOperationBehavior)()
    
    ' If the serializer is not found, create one and add it.
    If serializerBehavior Is Nothing Then
        serializerBehavior = New DataContractSerializerOperationBehavior(myOperationDescription)
        myOperationDescription.Behaviors.Add(serializerBehavior)
    End If
    
    ' Change settings of the behavior.
    serializerBehavior.MaxItemsInObjectGraph = 10000
    serializerBehavior.IgnoreExtensionDataObject = True
    
    sh.Open()
    Console.WriteLine("Listening")
    Console.ReadLine()

End Sub

Commenti

DataContractSerializerOperationBehavior attiva il controllo di opzioni DataContractSerializer, quali le proprietà MaxItemsInObjectGraph e IgnoreExtensionDataObject. Alcune di queste proprietà possono essere impostate soltanto utilizzando il costruttore della classe. In questo caso, è possibile sostituire DataContractSerializer utilizzando il metodo CreateSerializer. Per altre informazioni sui contratti dati, vedere Uso dei contratti dati.

Per altre informazioni sull'uso DataContractSerializerOperationBehavior di per sostituire l'oggetto IDataContractSurrogate restituito dalla DataContractSurrogate proprietà , vedere Surrogati del contratto dati.
