Hi,

Welcome to our Microsoft Q&A platform!

Do you want to get all files?You can try the following code:

 string path = @"xxxxxx";
            DirectoryInfo root = new DirectoryInfo(path);
            FileInfo[] files = root.GetFiles();
            foreach (var item in files)
            {
                var fileStream = new FileStream(item.FullName, FileMode.Open);
                using (StreamReader reader = new StreamReader(fileStream))
                {

                }
            }

Thanks.
