                int BufferLength = 2048; 
                byte[] b = new byte[BufferLength];
                int i;
                while ((i = fs.Read(b, 0, BufferLength)) > 0)
                {
                    stream.Write(b, 0, i);
                }
                stream.Close();
                stream.Dispose();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
    }
}

追问

我只能说这是单线程，我现在了解到FTP不能做到几人同时上传文件。所以改变了代码。谢谢你的代码。
