轉換IEnumerable <string> 進入IEnumerable <FileInfo>

Question

有沒有辦法從Directory.EnumerateDirectories(..)獲取IEnumerable<FileInfo> ？

我的方法看起來像這樣。

public static IEnumerable<String> EnumerateFiles(String path, String searchPattern, SearchOption searchOpt)
{
    try
    {
        IEnumerable<string> dirFiles = Enumerable.Empty<String>();
        if (searchOpt == SearchOption.AllDirectories)
        {
            dirFiles = Directory.EnumerateDirectories(path)
                                .SelectMany(x => EnumerateFiles(x, searchPattern, searchOpt));
        }
        return dirFiles.Concat(Directory.EnumerateFiles(path, searchPattern));
    }
    catch (UnauthorizedAccessException ex)
    {
        return Enumerable.Empty<String>();
    }
}

我也喜歡實施：

public static IEnumerable<FileInfo> EnumerateFiles(String path, String searchPattern, SearchOption searchOpt)
{
  //...code
}

嘗試改用DirectoryInfo.EnumerateFiles
