  Encoding encode = new System.Text.UTF8Encoding(false);                                List<Class> cles = ClassService.Instance().FindAll();                     FileStream stream = new FileStream(TempPath + "\\school_class.txt", FileMode.OpenOrCreate);                    using (StreamWriter sw = new StreamWriter(stream, encode))                    {                        rt.AppendText("写入文件: school_class.txt\r\n");                        string title = "id\tname";                        sw.WriteLine(title);                        rt.AppendText(title + "\r\n");                        foreach (Class s in cles)                        {                            string content = s.Id + "\t" + s.Name;                            sw.WriteLine(content);                            rt.AppendText(content + "\r\n");                        }                                                     }                    stream.Close();
