Exemplos

O exemplo de código a seguir mostra o manipulador do ReleaseRequestState evento em um módulo de estado de sessão personalizado. Se a sessão tiver sido abandonada, o módulo executará o evento Session_OnEnd definido no arquivo Global.asax para o aplicativo usando o RaiseSessionEnd método . Este exemplo de código faz parte de um exemplo maior fornecido para a SessionStateUtility classe .

//
// Event handler for HttpApplication.ReleaseRequestState
//

private void OnReleaseRequestState(object source, EventArgs args)
{
    HttpApplication app = (HttpApplication)source;
    HttpContext context = app.Context;
    string sessionID;

    // Read the session state from the context
    HttpSessionStateContainer stateProvider =
      (HttpSessionStateContainer)(SessionStateUtility.GetHttpSessionStateFromContext(context));

    // If Session.Abandon() was called, remove the session data from the local Hashtable
    // and execute the Session_OnEnd event from the Global.asax file.
    if (stateProvider.IsAbandoned)
    {
        try
        {
            pHashtableLock.AcquireWriterLock(Int32.MaxValue);

            sessionID = pSessionIDManager.GetSessionID(context);
            pSessionItems.Remove(sessionID);
        }
        finally
        {
            pHashtableLock.ReleaseWriterLock();
        }

        SessionStateUtility.RaiseSessionEnd(stateProvider, this, EventArgs.Empty);
    }

    SessionStateUtility.RemoveHttpSessionStateFromContext(context);
}

Comentários

O RaiseSessionEnd método é usado por um módulo de estado de sessão para executar o evento Session_OnEnd definido no arquivo Global.asax para um aplicativo ASP.NET. Um módulo de estado de sessão chamará o RaiseSessionEnd método quando uma sessão tiver sido abandonada ou se a sessão expirar.
