Public Interface IBindingDeliveryCapabilities

Beispiele

Das folgende Beispiel erfordert, dass eine CalculatorService mit sortierter Nachrichtenübermittlung vom WSHttpBinding verwendet wird. Zuverlässige Sitzungen und Warteschlangenübermittlungen werden standardmäßig nicht mit dieser Bindung verwendet, sie können jedoch aktiviert werden.

<!-- 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;  
  }  
}  

Hinweise

Die IBindingDeliveryCapabilities-Schnittstelle muss von einer Bindung implementiert werden, damit Clients und Dienste im Rahmen des Vertrags bestimmen können, dass die erforderlichen Features von der Bindung bereitgestellt werden.
