Esempio

Nell'esempio seguente viene DataContractSerializerOperationBehavior trovato nella raccolta di comportamenti per un'operazione e vengono reimpostate le MaxItemsInObjectGraph proprietà e IgnoreExtensionDataObject .

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 abilita il controllo delle DataContractSerializer opzioni, ad esempio le MaxItemsInObjectGraph proprietà e IgnoreExtensionDataObject . Alcune di queste proprietà possono essere impostate solo usando il costruttore della classe . In tal caso, può DataContractSerializer essere sostituito utilizzando il CreateSerializer metodo . Per altre informazioni sui contratti dati, vedere Uso di contratti dati.

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