HttpSessionStateContainer 생성자

정의

네임스페이스:

System.Web.SessionState

어셈블리:

System.Web.dll

새 HttpSessionStateContainer 개체를 만들고 지정된 설정과 값으로 초기화합니다.

public:
 HttpSessionStateContainer(System::String ^ id, System::Web::SessionState::ISessionStateItemCollection ^ sessionItems, System::Web::HttpStaticObjectsCollection ^ staticObjects, int timeout, bool newSession, System::Web::HttpCookieMode cookieMode, System::Web::SessionState::SessionStateMode mode, bool isReadonly);

public HttpSessionStateContainer (string id, System.Web.SessionState.ISessionStateItemCollection sessionItems, System.Web.HttpStaticObjectsCollection staticObjects, int timeout, bool newSession, System.Web.HttpCookieMode cookieMode, System.Web.SessionState.SessionStateMode mode, bool isReadonly);

new System.Web.SessionState.HttpSessionStateContainer : string * System.Web.SessionState.ISessionStateItemCollection * System.Web.HttpStaticObjectsCollection * int * bool * System.Web.HttpCookieMode * System.Web.SessionState.SessionStateMode * bool -> System.Web.SessionState.HttpSessionStateContainer

Public Sub New (id As String, sessionItems As ISessionStateItemCollection, staticObjects As HttpStaticObjectsCollection, timeout As Integer, newSession As Boolean, cookieMode As HttpCookieMode, mode As SessionStateMode, isReadonly As Boolean)

매개 변수

id

String

새 세션의 세션 식별자입니다. null이면 ArgumentException이 throw됩니다.

sessionItems

ISessionStateItemCollection

새 세션 상태 공급자의 세션 값이 포함된 ISessionStateItemCollection입니다.

staticObjects

HttpStaticObjectsCollection

ASP.NET 애플리케이션 파일 Global.asax에서 <object Runat="Server" Scope="Session"/> 태그로 선언된 개체를 지정하는 HttpStaticObjectsCollection입니다.

timeout

Int32

세션 상태 공급자가 세션을 종료하기 전에 요청 사이에 허용되는 시간(분)입니다.

newSession

Boolean

세션을 현재 요청으로 만들었음을 나타내면 true이고, 그렇지 않으면 false입니다.

cookieMode

HttpCookieMode

새 세션 상태 공급자의 CookieMode입니다.

mode

SessionStateMode

현재 세션 상태 모드를 지정하는 SessionStateMode 값 중 하나입니다.

isReadonly

Boolean

세션이 읽기 전용임을 나타내면 true이고, 그렇지 않으면 false입니다.

예외

ArgumentNullException

id이(가) null인 경우

예제

다음 코드 예제는 AcquireRequestState 채우는 새 사용자 지정 세션 상태 모듈에 대 한 이벤트 처리기 HttpSessionStateContainer 신규 또는 기존 세션 정보를 사용 하 여 개체에 추가 합니다는 HttpContext 를사용하여현재요청의AddHttpSessionStateToContext메서드. 사용자 지정 세션 상태 모듈의 전체 코드 예제를 참조 하세요.를 SessionStateUtility 클래스 개요입니다.
