DOTA版设计模式——备忘录

备忘录模式，最直接的就是记录游戏进度了，如果有个18关的游戏不能记录游戏进度，每次都必须从第一关开始玩，那你是不是要放弃游戏了，我肯定会的，嘿嘿。
在C#中序列化使我们能够更方便的完成备忘录模式，UML图先给大家一个概念：

具体代码见完整代码。
测试代码：
            DotaPatternLibrary.Memento.Game game = new DotaPatternLibrary.Memento.Game();
            game.GameLevel = 1;
            LandpyForm.Form.OutputResult("GameLevel:" + game.GameLevel);
            LandpyForm.Form.OutputResult("Ten minute left");
            game.GameLevel = 5;
            LandpyForm.Form.OutputResult("GameLevel:" + game.GameLevel);
            LandpyForm.Form.OutputResult("SaveGame");
            DotaPatternLibrary.Memento.GameProgress gameProgress = game.GetGameProgress();
            System.Runtime.Serialization.IFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
            System.IO.FileStream fsObj = new System.IO.FileStream("GameProgress.dat", System.IO.FileMode.Create);
            formatter.Serialize(fsObj, gameProgress);
            fsObj.Close();
            LandpyForm.Form.OutputResult("Save OK");
            Thread.Sleep(3000);
            LandpyForm.Form.OutputResult("3 second left");

            System.IO.FileStream fsObj2 = new System.IO.FileStream("GameProgress.dat", System.IO.FileMode.Open);
            gameProgress = formatter.Deserialize(fsObj2) as DotaPatternLibrary.Memento.GameProgress;
            DotaPatternLibrary.Memento.Game game2 = new DotaPatternLibrary.Memento.Game();
            LandpyForm.Form.OutputResult("GameLevel:" + game2.GameLevel);
            LandpyForm.Form.OutputResult("LoadGame");
            game2.SetProgress(gameProgress);
            LandpyForm.Form.OutputResult("GameLevel:" + game2.GameLevel);
