MoveTo(String)

지정된 파일을 새 위치로 이동하고 새 파일의 이름을 지정할 수 있는 옵션을 제공합니다.

MoveTo(String, Boolean)

새 파일 이름을 지정하고 대상 파일이 이미 있으면 덮어쓰는 옵션을 제공하여, 지정된 파일을 새 위치로 이동합니다.

MoveTo(String)

Source:
FileInfo.cs
Source:
FileInfo.cs
Source:
FileInfo.cs

지정된 파일을 새 위치로 이동하고 새 파일의 이름을 지정할 수 있는 옵션을 제공합니다.

public:
 void MoveTo(System::String ^ destFileName);
public void MoveTo (string destFileName);
member this.MoveTo : string -> unit
Public Sub MoveTo (destFileName As String)

매개 변수

destFileName
String

파일을 이동할 경로입니다. 이 경로에서 다른 파일 이름을 지정할 수 있습니다.

예외

대상 파일이 이미 있거나 대상 디바이스가 준비되지 않은 것과 같은 I/O 오류가 발생합니다.

destFileName이(가) null인 경우

2.1보다 오래된 .NET Framework 및 .NET Core 버전: destFileName 가 비어 있거나 공백만 포함하거나 잘못된 문자를 포함합니다.

호출자에게 필요한 권한이 없는 경우

destFileName 가 읽기 전용이거나 디렉터리입니다.

파일을 찾을 수 없습니다.

지정된 경로가 잘못되었습니다(예: 매핑되지 않은 드라이브에 있음).

지정된 경로, 파일 이름 또는 둘 다가 시스템에서 정의한 최대 길이를 초과합니다.

destFileName의 문자열 중간에 콜론(:)이 있습니다.

예제

다음 예제에서는 파일을 다른 위치로 이동하고 파일 이름을 바꾸는 방법을 보여 줍니다.

설명

이 메서드는 디스크 볼륨에서 작동합니다. 예를 들어 파일 c:\MyFile.txt d:\public로 이동하고 NewFile.txt 이름을 바꿀 수 있습니다.

이 메서드는 대상 파일이 이미 있는 경우 덮어쓰지 않습니다. 이를 위해 대신 를 호출 MoveTo(String, Boolean) 합니다.

추가 정보

적용 대상

MoveTo(String, Boolean)

Source:
FileInfo.cs
Source:
FileInfo.cs
Source:
FileInfo.cs

새 파일 이름을 지정하고 대상 파일이 이미 있으면 덮어쓰는 옵션을 제공하여, 지정된 파일을 새 위치로 이동합니다.

public:
 void MoveTo(System::String ^ destFileName, bool overwrite);
public void MoveTo (string destFileName, bool overwrite);
member this.MoveTo : string * bool -> unit
Public Sub MoveTo (destFileName As String, overwrite As Boolean)

매개 변수

destFileName
String

파일을 이동할 경로입니다. 이 경로에서 다른 파일 이름을 지정할 수 있습니다.

overwrite
Boolean

대상 파일이 이미 있는 경우 덮어쓰려면 true로 설정하고, 그렇지 않으면 false로 설정합니다.

예외

대상 디바이스가 준비되지 않은 경우와 같은 I/O 오류가 발생했습니다.

destFileName이(가) null인 경우

2.1보다 오래된 .NET Framework 및 .NET Core 버전: destFileName 가 비어 있거나 공백만 포함하거나 잘못된 문자를 포함합니다.

호출자에게 필요한 권한이 없는 경우

destFileName 가 읽기 전용이거나 디렉터리입니다.

파일을 찾을 수 없습니다.

지정된 경로가 잘못되었습니다(예: 매핑되지 않은 드라이브에 있음).

지정된 경로, 파일 이름 또는 둘 다가 시스템에서 정의한 최대 길이를 초과합니다.

destFileName의 문자열 중간에 콜론(:)이 있습니다.

예제

다음 예제에서는 파일을 다른 위치로 이동하고 파일 이름을 바꾸는 방법을 보여 줍니다.
