上一篇新增遊戲狀態的控制，這一篇預計加入遊戲回合數與玩家輸贏次數，但若是用上一篇的作法，會多存好幾個Session，控制上也比較分散，所以來優化一下作法，就是新增一個類別專門來儲存這些控制變數
新增一個Game類別
//**新增**
public class Game
{
public int totalRound { get; set; } //遊戲回合
public int playerWin { get; set; } //玩家贏的局數
public int dealerWin { get; set; } //玩家輸的局數
public int tie { get; set; } //平局的局數
public int status { get; set; } //遊戲狀態
public Game()
{
totalRound = 1;
playerWin = 0;
dealerWin = 0;
tie = 0;
status = 0; //0-遊戲中，1-結束
}
}
再調整原本的status的程式碼，並在牌局結束的地方統計回合與輸贏次數
最後加做一個可隱藏牌堆的Checkbox，以下是完整的程式碼

執行結果
以上由C# ASP.NET開發的21點撲克牌遊戲，到此結束。
未來也可以繼續延伸，例如用資料庫記錄遊戲狀態；或可以讓多個使用者遊玩並記錄；或是讓多人一起玩...等新增遊戲功能或變更架構，甚至開發遊戲平台串接多個遊戲。
