Public Interface IBindingDeliveryCapabilities

Exemples

L'exemple suivant requiert que CalculatorService utilise une WSHttpBinding avec remise de messages ordonnée. Les sessions fiables et la remise en file d'attente ne sont pas utilisées par défaut avec cette liaison, mais peuvent être activées.

<!-- Here is the configuration for a CalculatorService using a WSHttpBinding with ordered message delivery required. -->  
<?xml version="1.0" encoding="utf-8" ?>  
<configuration>  
   <system.serviceModel>  
      <services>  
         <service   
             type="Microsoft.ServiceModel.Samples.CalculatorService">  
            <!-- Use base address provided by host and a WSHttpBinding named "Binding1" -->  
            <endpoint address=""  
                      binding="wsHttpBinding"  
                      bindingConfiguration="Binding1"   
                      contract="Microsoft.ServiceModel.Samples.ICalculator" />  
         </service>  
      </services>  

      <bindings>  
         <wsHttpBinding>   
            <binding name="Binding1">           
               <!-- The next element enables a ReliableSession and required ordered delivery-->  
      <reliableSession enabled="true" ordered="true"/>  
      </binding>  
         </wsHttpBinding>  
      </bindings>  

   </system.serviceModel>  
</configuration>  

// The CalculatorService configuration has enabled a reliable session  
// with ordered delivery set to true. This means that the binding  
// requirement for ordered delivery specified by the  
// BindingRequirementsAttribute on the CalculatorService class  
// implemented below will be satisfied by this WSHttpBinding.  

using System;  
using System.ServiceModel;  

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

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

[BindingRequirements(  
  QueuedDeliveryRequirements=RequirementsMode.Disallow,  
  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;  
  }  
}  

Remarques

L'interface IBindingDeliveryCapabilities doit être implémentée par une liaison si les clients et les services doivent être en mesure de stipuler, dans le cadre de leur contrat, que les fonctionnalités dont ils ont besoin sont fournies par la liaison.
