FileSystemWatcher.Renamed 이벤트

정의

지정된 Path에 있는 파일이나 디렉터리의 이름이 바뀔 경우에 발생합니다.

public:
 event System::IO::RenamedEventHandler ^ Renamed;
public event System.IO.RenamedEventHandler? Renamed;
public event System.IO.RenamedEventHandler Renamed;
[System.IO.IODescription("FSW_Renamed")]
public event System.IO.RenamedEventHandler Renamed;
member this.Renamed : System.IO.RenamedEventHandler 
[<System.IO.IODescription("FSW_Renamed")>]
member this.Renamed : System.IO.RenamedEventHandler 
Public Custom Event Renamed As RenamedEventHandler

예제

다음 예제에서는 감시된 파일의 Renamed 이름이 바뀔 때마다 이벤트를 사용하여 콘솔에 대한 파일 경로를 표시합니다.

설명

이벤트는 RenamedRenamedEventHandler 다음 서명이 있는 대리자입니다.

public delegate void Renamed(object sender, RenamedEventArgs e);
Public Delegate Sub RenamedEventHandler(sender As Object, e As RenamedEventArgs)

개체는 RenamedEventArgs 이름 바꾸기의 형식( ChangeType 속성), 이전 및 새 이름, 이전 및 새 경로와 같은 이름 바꾸기 작업에 대한 정보를 제공합니다. 속성이 Name 운영 체제에서 이전 및 새 이름 이벤트와 일치하지 않는 경우 FileSystemWatcher 이름이 바뀐 이벤트에 대해 null일 수 있습니다.

보고 있는 디렉터리의 이름을 변경해도 알림이 발생하지 않습니다. 보고 있는 디렉터리 내의 항목에 대해서만 알림이 발생합니다.
