 static void RemoveHttpSessionStateFromContext(System::Web::HttpContext ^ context);

public static void RemoveHttpSessionStateFromContext (System.Web.HttpContext context);

static member RemoveHttpSessionStateFromContext : System.Web.HttpContext -> unit

Public Shared Sub RemoveHttpSessionStateFromContext (context As HttpContext)

매개 변수

context

HttpContext

세션 데이터를 제거할 HttpContext입니다.

예제

다음 코드 예제에서는 사용자 지정 세션 상태 모듈에서 ReleaseRequestState 이벤트에 대 한 처리기를 보여 입니다. 이벤트 처리기는 현재 HttpContext에서 세션 데이터를 제거합니다. 이 코드 예제는에 대해 제공 된 큰 예제의 일부는 SessionStateUtility 클래스입니다.

//
// 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);
}

End Sub

설명

메서드는 RemoveHttpSessionStateFromContext 지정된 HttpContext에서 세션 데이터를 지웁니다. 세션 상태 모듈은 이벤트에 대한 처리기에서 메서드를 호출 RemoveHttpSessionStateFromContext 합니다 ReleaseRequestState .
