Ejemplos

El ejemplo siguiente busca DataContractSerializerOperationBehavior en la colección de comportamientos para una operación y restablece las propiedades MaxItemsInObjectGraph y 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;

Comentarios

DataContractSerializerOperationBehavior habilita el control de las opciones de DataContractSerializer, como las propiedades MaxItemsInObjectGraph y IgnoreExtensionDataObject. Algunas de estas propiedades solo se pueden establecer utilizando el constructor de la clase. En ese caso, DataContractSerializer se puede reemplazar utilizando el método CreateSerializer. Para obtener más información sobre los contratos de datos, consulte Utilización de contratos de datos.

Para obtener más información sobre el uso de DataContractSerializerOperationBehavior para reemplazar el IDataContractSurrogate devuelto por la DataContractSurrogate propiedad , vea Suplentes del contrato de datos.
