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 con la ReleaseInstanceMode propiedad para informar a Windows Communication Foundation (WCF) que el objeto de servicio actual se debe reciclar en un punto determinado del proceso de invocación. ReleaseInstanceModeUse 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.
