找不到目录名称

我想从路径获取目录名称，但是它返回以下错误：

目录名称无效

以下是示例路径：

strFilePathName = C：\ inetpub \ wwwroot \ PSSWeb \ foldername \ xxx.ini

以下Directoryname基于前缀PSS用来获取的代码，其应返回PSSWeb。我无法找到解决方案。

var directories = Directory.GetDirectories(strFilePathName,
                                           "PSS?",
                                           SearchOption.AllDirectories);

您指定的路径名“ C：\ inetpub \ wwwroot \ PSSWeb \ foldername \ xxx.ini”不是目录，而是文件。

    //
    // Summary:
    //     Returns the names of the subdirectories (including their paths) that match the
    //     specified search pattern in the specified directory, and optionally searches
    //     subdirectories.
    //
    // Parameters:
    //   path:
    //     The relative or absolute path to the directory to search. This string is not
    //     case-sensitive.
    //
    //   searchPattern:
    //     The search string to match against the names of subdirectories in path. This
    //     parameter can contain a combination of valid literal and wildcard characters
    //     (see Remarks), but doesn't support regular expressions.
    //
    //   searchOption:
    //     One of the enumeration values that specifies whether the search operation should
    //     include all subdirectories or only the current directory.
    //
    // Returns:
    //     An array of the full names (including paths) of the subdirectories that match
    //     the specified criteria, or an empty array if no directories are found.
    //
    // Exceptions:
    //   T:System.ArgumentException:
    //     path is a zero-length string, contains only white space, or contains one or more
    //     invalid characters. You can query for invalid characters by using the System.IO.Path.GetInvalidPathChars
    //     method.-or- searchPattern does not contain a valid pattern.
    //
    //   T:System.ArgumentNullException:
    //     path or searchPattern is null.
    //
    //   T:System.ArgumentOutOfRangeException:
    //     searchOption is not a valid System.IO.SearchOption value.
    //
    //   T:System.UnauthorizedAccessException:
    //     The caller does not have the required permission.
    //
    //   T:System.IO.PathTooLongException:
    //     The specified path, file name, or both exceed the system-defined maximum length.
    //     For example, on Windows-based platforms, paths must be less than 248 characters
    //     and file names must be less than 260 characters.
    //
    //   T:System.IO.IOException:
    //     path is a file name.
    //
    //   T:System.IO.DirectoryNotFoundException:
    //     The specified path is invalid (for example, it is on an unmapped drive).
    public static string[] GetDirectories(string path, string searchPattern, SearchOption searchOption);

多数民众赞成在该方法的文档。提到第一个参数必须是目录。
