Beispiele

Im folgenden Beispiel wird die DataContractSerializerOperationBehavior in der Auflistung von Verhaltensweisen für einen Vorgang ermittelt und die und IgnoreExtensionDataObject die MaxItemsInObjectGraph Eigenschaften zurückgesetzt.

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

Hinweise

Dies DataContractSerializerOperationBehavior ermöglicht die Steuerung von DataContractSerializer Optionen, z. B. die und IgnoreExtensionDataObject die MaxItemsInObjectGraph Eigenschaften. Einige dieser Eigenschaften können nur mithilfe des Konstruktors der Klasse festgelegt werden. In diesem Fall kann die DataContractSerializer Methode mithilfe der CreateSerializer Methode ersetzt werden. Weitere Informationen zu Datenverträgen finden Sie unter Verwenden von Datenverträgen.

Weitere Informationen zum Ersetzen der DataContractSerializerOperationBehaviorIDataContractSurrogate von der DataContractSurrogate Eigenschaft zurückgegebenen Daten finden Sie unter "Datenvertragsübergaben".
