예제

다음 예제에서는 GetInvalidFileNameChars 메서드 및 GetInvalidPathChars 메서드가 잘못 된 문자를 검색 하는 방법을 보여 줍니다.The following example demonstrates the GetInvalidFileNameChars method and the GetInvalidPathChars method to retrieve invalid characters.

using namespace System::IO;

설명

이 메서드에서 반환 된 배열에는 파일 및 디렉터리 이름에 사용할 수 없는 전체 문자 집합이 포함 되지 않을 수 있습니다.The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names. 잘못 된 문자의 전체 집합은 파일 시스템에 따라 다를 수 있습니다.The full set of invalid characters can vary by file system. 예를 들어 Windows 기반 데스크톱 플랫폼에서 잘못 된 경로 문자에는 파이프 (|)와 null (\ 0) 뿐만 아니라 ASCII/유니코드 문자 1 ~ 31도 포함 될 수 있습니다.For example, on Windows-based desktop platforms, invalid path characters might include ASCII/Unicode characters 1 through 31, as well as pipe (|) and null (\0).
