备忘录模式

备忘录模式的作用就是存档。

比如你在玩一个可以存档的游戏。例如红警。你玩的很好，你想存起来下次接着玩。这个就是备忘录模式，代码如何实现呢？

使用代码：

  BaseMemento BaseMemento1 = new BaseMemento();

            LOL l1 = new LOL() { level = 1, Equipment = "红药水，罗兰之剑" };
            
            BaseMemento1.Save("第一次", l1);

            LOL l2 = new LOL() { level = 6, Equipment = "电剑" };

            BaseMemento1.Save("第二次", l2);

            LOL l3 = new LOL() { level = 10, Equipment = "电剑，鞋子s" };

            BaseMemento1.Save("第三次", l3);

            BaseMemento1.Get("第一次").Show();

            BaseMemento1.Get("第二次").Show();

            BaseMemento1.Get("第三次").Show();

            Console.ReadLine();

对象：

    public class LOL
    {
        public int level { get; set; }
        public string Equipment { get; set; }

        public void Show()
        {
            Console.WriteLine("level={0}，Equipment={1}", level, Equipment);
        }

    }

备忘录：

    public class BaseMemento
    {
        public bool Save(string Name, LOL lol)
        {

            SerializeHelper.JsonSerializeHelper.Serialize<LOL, Stream>(lol, new FileStream(string.Format("{0}.txt", Name), FileMode.OpenOrCreate));

            return true;
        }
        public LOL Get(string Name)
        {

            using (FileStream fsRead = new FileStream(string.Format("{0}.txt", Name), FileMode.Open))
            {
                int fsLen = (int)fsRead.Length;
                byte[] heByte = new byte[fsLen];
                int r = fsRead.Read(heByte, 0, heByte.Length);
                string myStr = System.Text.Encoding.UTF8.GetString(heByte);
                return SerializeHelper.JsonSerializeHelper.Deserialize<LOL>(myStr);
            }


        }
    }

结果：
