Redis存取序列化与反序列化性能问题详解

  List<User> list = new List<User>();
  for (int i = 0; i < 1000; i++)
  {
   User user = new User() { Id = i, Name = "张三", Age = 11 };
   list.Add(user);
  }
  Stopwatch stopwatch = new Stopwatch();
  stopwatch.Start(); // 开始监视代码运行时间

  //使用序列化
  rds.HSet("test2", "test2", list);
  var list1 = rds.HGet<List<User>>("test2", "test2");

  //使用byte方式
  //rds.HSet("test", "test1", ObjectToBytes(list));
  //var list2 = BytesToObject(rds.HGet<byte[]>("test", "test1"));

  stopwatch.Stop(); // 停止监视
  TimeSpan timespan = stopwatch.Elapsed; // 获取当前实例测量得出的总时间
  double hours = timespan.TotalHours; // 总小时
  double minutes = timespan.TotalMinutes; // 总分钟
  double seconds = timespan.TotalSeconds; // 总秒数
  double milliseconds = timespan.TotalMilliseconds;
  Console.WriteLine(+hours + " " + minutes + " " + seconds + " " + milliseconds);
  Console.ReadKey();
