설명

클래스에는 FileSystemInfo 파일 및 디렉터리 조작에 공통적인 메서드가 포함되어 있습니다. 개체는 FileSystemInfo 파일 또는 디렉터리를 나타낼 수 있으므로 개체의 기초 FileInfo 역할을 합니다 DirectoryInfo . 많은 파일 및 디렉터리를 구문 분석할 때 이 기본 클래스를 사용합니다.

파생 클래스는 파생 클래스에 FileSystemInfo 열거형의 AllAccess 권한이 있는 경우에만 상속할 FileIOPermissionAccess 수 있습니다.

경로를 수락하는 멤버에서 경로는 파일 또는 디렉터리를 참조할 수 있습니다. 지정된 경로는 서버 및 공유 이름에 대한 상대 경로 또는 UNC(범용 명명 규칙) 경로를 참조할 수도 있습니다. 예를 들어 다음 모든 경로는 허용 가능한 경로입니다.

• C#의 "c:\\MyDir\\MyFile.txt" 또는 Visual Basic의 "c:\MyDir\MyFile.txt"

• C#의 "c:\\MyDir" 또는 Visual Basic의 "c:\MyDir"

• C#의 "MyDir\\MySubdir" 또는 Visual Basic의 "MyDir\MySubDir"

• C#의 "\\\\MyServer\\MyShare" 또는 Visual Basic의 "\\MyServer\MyShare"
