【问题描述】：

我可以从 sftp 服务器获取文件的文件名，但我不会读取文件。我想要的是从 sftp 服务器读取文件，然后解析文本文件而不在本地保存文件，然后将其存储在另一个 sftp 服务器上。代码如下。

        const string host = "*****";
        const string username = "*****";
        const string password = "*****";
        const int port = 22;
        const string workingdirectory = "/folder";
      
        long date = Convert.ToInt64(DateTime.Now.AddDays(-2).ToString("ddMMyy"));
        string dates = Convert.ToString(date);
        //Console.WriteLine(responseText);
        string fileName = "asr" + dates + ".txt";

        Console.WriteLine("Creating client and connecting");
        using (var client = new SftpClient(host, port, username, password))
        {
            client.Connect();
            Console.WriteLine("Connected to {0}", host);

            client.ChangeDirectory(workingdirectory);

            var listDirectory = client.ListDirectory(workingdirectory);
            
            Console.WriteLine("Listing directory:");
            foreach (var fi in listDirectory)
            {               
                Console.WriteLine("Changed directory to {0}", workingdirectory);
                if (fi.Name.Contains("asr010322.txt"))
                {
                    Console.WriteLine(fi.Name);
                    StreamReader reader = new StreamReader(fileName);
                    Console.WriteLine(reader);
                }                   
            }
            using (var fileStream = new FileStream(uploadfile, FileMode.Open))
            {
                Console.WriteLine("Uploading {0} ({1:N0} bytes)", uploadfile, fileStream.Length);
                client.BufferSize = 4 * 1024; // bypass Payload error large files
                client.UploadFile(fileStream, Path.GetFileName(uploadfile));
            }
        }

【问题讨论】：

• string content = reader.ReadToEnd(); 而不是尝试打印阅读器本身？
