SessionStateUtility.RaiseSessionEnd Metoda

Definice

Spustí událost Session_OnEnd definovanou v souboru Global.asax pro aplikaci ASP.NET.

public:
 static void RaiseSessionEnd(System::Web::SessionState::IHttpSessionState ^ session, System::Object ^ eventSource, EventArgs ^ eventArgs);
public static void RaiseSessionEnd (System.Web.SessionState.IHttpSessionState session, object eventSource, EventArgs eventArgs);
static member RaiseSessionEnd : System.Web.SessionState.IHttpSessionState * obj * EventArgs -> unit
Public Shared Sub RaiseSessionEnd (session As IHttpSessionState, eventSource As Object, eventArgs As EventArgs)

Parametry

session
IHttpSessionState

Instance IHttpSessionState implementace pro relaci, která skončila.

eventSource
Object

Objekt zdroje události, který se má události poskytnout Session_OnEnd .

eventArgs
EventArgs

Objekt EventArgs , který Session_OnEnd se má události poskytnout.

Příklady

Následující příklad kódu ukazuje obslužnou rutinu ReleaseRequestState pro událost ve vlastním modulu stavu relace. Pokud byla relace zrušena, modul spustí událost Session_OnEnd definovanou v souboru Global.asax pro aplikaci pomocí RaiseSessionEnd metody . Tento příklad kódu je součástí většího příkladu SessionStateUtility pro třídu .

//
// 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);
}

    ' and execute the Session_OnEnd event from the Global.asax file.
    If stateProvider.IsAbandoned Then
        Try

            sessionID = pSessionIDManager.GetSessionID(context)

Poznámky

Metodu RaiseSessionEnd používá modul stavu relace ke spuštění Session_OnEnd události definované v souboru Global.asax pro ASP.NET aplikaci. Modul stavu relace zavolá metodu , RaiseSessionEnd když byla relace zrušena nebo pokud relace vyprší.
