Egenskapsvärde

true instruerar Windows Communication Foundation (WCF) att bekräfta att bindningen måste stödja ordningen på meddelanden, annars false. Standardvärdet är false.

Exempel

I följande kodexempel används DeliveryRequirementsAttribute attributet för att instruera WCF att vid körning bekräfta att den faktiska bindningen stöder ordnade meddelanden.

using System;
using System.ServiceModel;

[ServiceContract]
interface ICalculatorService
{
  [OperationBehavior()]
  int Add(int a, int b);

  [OperationContract]
  int Subtract(int a, int b);
}

[DeliveryRequirementsAttribute(
  QueuedDeliveryRequirements=QueuedDeliveryRequirementsMode.NotAllowed,
  RequireOrderedDelivery=true
)]
class CalculatorService: ICalculatorService
{
  public int Add(int a, int b)

    Console.WriteLine("Add called.");
    return a + b;
  }

  public int Subtract(int a, int b)
  {
    Console.WriteLine("Subtract called.");
    return a - b;
  }

  public int Multiply(int a, int b)
  {
    return a * b;
  }
}

Om du anger egenskapen RequireOrderedDelivery till false instrueras WCF att inte utföra någon validering.
