Examples

다음 예제에서는 GetInvalidFileNameChars 메서드와 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;
using namespace System::IO;

namespace PathExample

    public ref class GetCharExample

    public:
        static void Main()
        {

            array<Char>^ invalidPathChars = Path::GetInvalidPathChars();

            Console::WriteLine("The following characters are invalid in a path:");
            ShowChars(invalidPathChars);
            Console::WriteLine();

            // Get a list of invalid file characters.
            array<Char>^ invalidFileChars = Path::GetInvalidFileNameChars();

            Console::WriteLine("The following characters are invalid in a filename:");
            ShowChars(invalidFileChars);
        }

        static void ShowChars(array<Char>^ charArray)
        {
            Console::WriteLine("Char\tHex Value");
            // Display each invalid character to the console.
            for each (Char someChar in charArray)
            {
                if (Char::IsWhiteSpace(someChar))
                {

    };
};

int main()

// Note: Some characters may not be displayable on the console.

Remarks

이 메서드에서 반환 된 배열 전체 파일 및 디렉터리 이름에 잘못 된 문자 집합을 포함 하는 보장 되지 않습니다.The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names. 전체 집합이 잘못 된 문자는 파일 시스템에 따라 달라질 수 있습니다.The full set of invalid characters can vary by file system. 예를 들어 Windows 기반 데스크톱 플랫폼에서 잘못 된 경로 문자에는 ASCII/유니코드 문자 1 ~ 31, 따옴표 ("), 보다 작음 (<), 보다 큼 (>), 파이프 (|), 백스페이스 (\b), null (\ 0) 및 탭 (\t)이 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 quote ("), less than (<), greater than (>), pipe (|), backspace (\b), null (\0) and tab (\t).
