次のコード例に示します、GetInvalidFileNameCharsメソッドとGetInvalidPathChars無効な文字を取得します。The following code 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()
        {
            // Get a list of invalid path characters.
            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)
            {

    };
};

int main()

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

注釈

このメソッドから返される配列は、ファイルとディレクトリ名に無効な文字の完全なセットを含むは保証されません。The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names. 無効な文字の完全なセットは、ファイル システムによって異なることができます。The full set of invalid characters can vary by file system. たとえば、Windows ベースのデスクトップ プラットフォームに無効なパス文字可能性があります Ascii/unicode 文字 1 ~ 31、だけでなく引用符 (") より小さい (<)、大なり (>)、パイプ (|)、バック スペース (\b)、null (\0)、およびタブ (\t)。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).
