.net - 如何获取 .Net 中 Windows 文件系统路径的所有有效文件夹和文件字符的列表

Question

System.IO.Path.GetInvalidPathChars() 给出无效字符列表。

但我需要有所有有效字符的列表。

第一个想到的简单想法是从 0 到 255 进行迭代并排除无效字符，但它会只给出有效字符吗？还有 Unicode 呢？我应该从 0 迭代到 65535 吗？

Answer 1

据我所知，.NET 中没有任何东西可以获取此信息。

您可以查看以下 Microsoft 页面:http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx

Use any character in the current code page for a name, including Unicode characters and characters
in the extended character set (128–255), except for the following:

    The following reserved characters:

        < (less than)  
        > (greater than)
        : (colon)
        " (double quote)
        / (forward slash)
        \ (backslash)
        | (vertical bar or pipe)
        ? (question mark)
        * (asterisk)

    Integer value zero, sometimes referred to as the ASCII NUL character.

    Characters whose integer representations are in the range from 1 through 31,
    except for alternate data streams where these characters are allowed.

    Any other character that the target file system does not allow.
