Exempel

I följande exempel hittar du DataContractSerializerOperationBehavior i samlingen med beteenden för en åtgärd och återställer MaxItemsInObjectGraph egenskaperna och 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

Kommentarer

DataContractSerializerOperationBehavior Aktiverar kontrollen över DataContractSerializer alternativ, till exempel MaxItemsInObjectGraph egenskaperna ochIgnoreExtensionDataObject. Vissa av dessa egenskaper kan bara anges med hjälp av konstruktorn för klassen. I så fall DataContractSerializer kan du ersätta med hjälp av CreateSerializer metoden . Mer information om datakontrakt finns i Använda datakontrakt.

Mer information om hur du använder DataContractSerializerOperationBehavior för att ersätta den IDataContractSurrogate som returneras av DataContractSurrogate egenskapen finns i Data Contract Surrogates(Data contract surrogates).
