将字符串写入记事本

    string jsonStr = JsonConvert.SerializeObject(data);
                FileStream stream = new FileStream(@"C:UsersYeChangZhongDesktop新建文件夹aa.txt", FileMode.Create);//fileMode指定是读取还是写入
                StreamWriter writer = new StreamWriter(stream);
                writer.WriteLine("====================");
                writer.WriteLine(jsonStr);
                writer.WriteLine(data.CREATEUSERNAME);
                writer.WriteLine(data.MODIFYUSERNAME);
                writer.WriteLine("====================");
                writer.Close();//释放内存
                stream.Close();//释放内存
