InstallEventArgs.SavedState 속성

정의

네임스페이스:

System.Configuration.Install

어셈블리:

System.Configuration.Install.dll

설치의 현재 상태를 나타내는 IDictionary를 가져옵니다.

public:
 property System::Collections::IDictionary ^ SavedState { System::Collections::IDictionary ^ get(); };

public System.Collections.IDictionary SavedState { get; }

member this.SavedState : System.Collections.IDictionary

Public ReadOnly Property SavedState As IDictionary

속성 값

IDictionary

설치의 현재 상태를 나타내는 IDictionary입니다.

예제

다음 예제는 InstallEventArgs 생성자 및 SavedState 의 속성을 InstallEventArgs 클래스.

호출 하는 두 개의 새 이벤트가 BeforeCommit 고 AfterCommit입니다. 이러한 이벤트의 처리기 라는 보호 되는 메서드에서 호출 됩니다 OnBeforeCommit 고 OnAfterCommit 각각. 이러한 이벤트가 발생 하는 경우는 Commit 메서드가 호출 됩니다.
