Ejemplos

El código de ejemplo siguiente muestra el uso de ReleaseInstanceMode para reciclar los objetos de servicio antes y después de una llamada.The following example code shows the use of ReleaseInstanceMode to recycle service objects both before and after a call.

class SampleService : ISampleService
{
  private Guid id;
  private string session;

  public SampleService()
  {
    id = Guid.NewGuid();
    session = OperationContext.Current.SessionId;
    Console.WriteLine("Object {0} has been created.", id);
    Console.WriteLine("For session {0}", session);
  }
  [OperationBehavior(
          ReleaseInstanceMode=ReleaseInstanceMode.BeforeAndAfterCall
  )]
  public string  SampleMethod(string msg)
  {
    Console.WriteLine("The caller said: \"{0}\"", msg);
    Console.WriteLine("For session {0}", OperationContext.Current.SessionId);
    return "The service greets you: " + msg;
  }

  ~SampleService()
  {
    Console.WriteLine("Object {0} has been destroyed.", id);
    Console.WriteLine("For session {0}", session);
  }
}
 Friend Class SampleService
  Implements ISampleService
Private id As Guid
Private session As String

Public Sub New()
  id = Guid.NewGuid()
  session = OperationContext.Current.SessionId
  Console.WriteLine("Object {0} has been created.", id)
  Console.WriteLine("For session {0}", session)
End Sub
<OperationBehavior(ReleaseInstanceMode:=ReleaseInstanceMode.BeforeAndAfterCall)> _
Public Function SampleMethod(ByVal msg As String) As String Implements ISampleService.SampleMethod
  Console.WriteLine("The caller said: ""{0}""", msg)
  Console.WriteLine("For session {0}", OperationContext.Current.SessionId)
  Return "The service greets you: " & msg
End Function

Protected Overrides Sub Finalize()
  Console.WriteLine("Object {0} has been destroyed.", id)
  Console.WriteLine("For session {0}", session)
End Sub
 End Class

Comentarios

Use la ReleaseInstanceMode con el ReleaseInstanceMode propiedad para informar a Windows Communication Foundation (WCF) que el objeto de servicio actual debe reciclarse en un punto concreto en el proceso de invocación.Use the ReleaseInstanceMode with the ReleaseInstanceMode property to inform Windows Communication Foundation (WCF) that the current service object must be recycled at a particular point in the invocation process. El comportamiento predeterminado es reciclar un objeto de servicio según el valor InstanceContextMode.The default behavior is to recycle a service object according to the InstanceContextMode value.
