IBindingDeliveryCapabilities Interfaccia

Definizione

Definisce l'interfaccia che deve essere implementata dalle associazioni per descrivere e annunciare le funzionalità che client e servizi possono richiedere.Defines the interface that bindings must implement to describe and advertise the capabilities that clients and services may require.

public interface class IBindingDeliveryCapabilities
public interface IBindingDeliveryCapabilities
type IBindingDeliveryCapabilities = interface
Public Interface IBindingDeliveryCapabilities

Esempio

Per l'esempio seguente, CalculatorService deve utilizzare un WSHttpBinding con recapito dei messaggi ordinati.The following sample requires that CalculatorService must use a WSHttpBinding with ordered message delivery. Per impostazione predefinita, con questa associazione non vengono utilizzati sessioni affidabili e recapito in coda, ma possono essere attivati.Reliable sessions and queued delivery are not used by default with this binding, but can be enabled.

<!-- 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;  
  }  
}  

Commenti

L'interfaccia IBindingDeliveryCapabilities deve essere implementata da un'associazione, per fare in modo che client e servizi siano in grado di stabilire, come parte del contratto, che le funzionalità richieste vengano fornite dall'associazione.The IBindingDeliveryCapabilities interface must be implemented by a binding if clients and services are to be able to stipulate, as part of their contract, that the features they require are provided by the binding.

Proprietà

AssuresOrderedDelivery

Ottiene un valore che indica se l'associazione può supportare assicurazioni per il recapito di messaggi nell'ordine in cui sono stati inviati.Gets a value that indicates whether the binding can support assurances for the delivery of messages in the order they were sent.

QueuedDelivery

Ottiene un valore che indica se l'associazione può supportare il recapito in coda di messaggi.Gets a value that indicates whether the binding can support the queued delivery of messages.
