1出牌类型

enum CardType
        {
            None = 0,
            One = 1,
            Two = 2,
            Three = 3,
            ThreeWithOne = 4,
            ThreeWithTwo = 5,
            Four = 6,
            FourWith2One = 7,
            FourWith2Two = 8,
            Rocket = 9,
        }

每次出牌都是这9种类型：单张，对子，3连，3带1单，3带1对，4连，4带2个单，4带2个对，大小王

class CardRule
        {
            public CardType m_type;
            public int m_val; //选取的最小的牌值
            public int m_num = 1; //顺子的数量
    }

然后根据出牌判断牌型，例如a玩家出牌：12345，牌型m\_type=One，m\_val=1，m\_num=5。b玩家出牌：23456，牌型m\_type=One，m\_val=2，m\_num=5。满足m\_type一样，m\_val更大，m\_num一样，b玩家的牌就能吃掉a玩家。

例如a玩家出牌：3333444455667788，牌型m\_type=FourWith2Two，m\_val=3，m\_num=2。

## 2判断一次出牌中每张的数量 ##

static void mapCardCreate(List<int> list, ref Dictionary<int, int> dicCard)
            {
                for (int i = 0; i < list.Count; i++)
                {
                    if (dicCard.ContainsKey(list[i]) == false)
                    {
                        dicCard.Add(list[i], 1);
                    }
                    else
                    {
                        dicCard[list[i]]++;
                    }
                }
            }

用一个字典保存住，键是牌的值，值是这张牌的数量。例如：444422，字典为dic\[4\]=4，dic \[2\]=2.

## 3只有连牌的判断 ##

/// <summary>
            /// 只有顺子处理，例如：34567，334455，333444，44445555
            /// </summary>
            /// <param name="list">出的牌，例如34567</param>
            /// <param name="dicItem">每张牌数量的字典</param>
            /// <param name="dealType">当前处理连牌类型：单连，双连，三连，4连</param>
            /// <param name="val">牌型的最小值</param>
            /// <param name="num">连牌数量</param>
            /// <param name="cardType">牌型</param>
            /// <returns></returns>
            static bool shunOnlyDeal(List<int> list, Dictionary<int, int> dicItem, CardType dealType, ref int val,ref int num, ref CardType cardType)
            {
                int mod = 1;
                int firstVal = 1;
                switch (dealType)
                {
                    case CardType.Two:
                        firstVal = 2;
                        mod = 2;
                        break;
                    case CardType.Three:
                        firstVal = 3;
                        mod = 3;
                        break;
                    case CardType.Four:
                        firstVal = 4;
                        mod = 4;
                        break;
                }
                if (list.Count % mod != 0)
                {
                    return false;
                }
    
                int iNum = 0;
                int minVal = GMaxVal;
                List<int> listKey = new List<int>();
                foreach (var item in dicItem)
                {
                    if (item.Value != firstVal )
                    {
                        return false;
                    }
                    if (item.Value == firstVal)
                    {
                        iNum++;
                        listKey.Add(item.Key);
                    }
                    if ((item.Key < minVal) && item.Value == firstVal)
                    {
                        minVal = item.Key;
                    }  
                }
    
                if (listKey.Count >= 2)
                {
                    listKey.Sort((x, y) => x.CompareTo(y));
                    if (isInOrder(listKey) == false)
                    {
                        return false;
                    }
                }
                val = minVal;
                num = iNum;
                cardType = dealType;
                return true;
            }

例如：当出牌为334455时，双连牌时

1.出牌数量要为2的倍数

2.遍历记录每张牌数量的字典，找到最小牌值minVal =3，记录顺子数量iNum=3

3.得到每张单牌的list（3,4,5），如果它们是按顺序的，则是合法的牌型。

## 4连牌带牌的判断 ##

/// <summary>
            /// 连牌带牌处理，例如：3334，33344456，333345，33334455
            /// </summary>
            /// <param name="list">出的牌，从大到小排好顺序的</param>
            /// <param name="dicItem">记录每张牌个数的字典</param>
            /// <param name="dealType">处理的类型：3带1单，3带一对，4带2单，4带2对</param>
            /// <param name="val">牌的最小值</param>
            /// <param name="num">牌型数量</param>
            /// <param name="cardType">牌型</param>
            /// <returns></returns>
            static bool shunWithDeal(List<int> list, Dictionary<int, int> dicItem, CardType dealType,ref int val, ref int num,ref CardType cardType)
            {
                int mod = 1;
                int firstVal = 1;//顺子的牌要连几张，3带1，连3张
                int withVal = 1;//顺子带的牌要带几张，3带1，带1张
                int multiple = 1;//顺子与带牌的倍数关系，3带1，倍数为1张
                switch (dealType)
                {
                    case CardType.ThreeWithOne:
                        firstVal = 3;
                        withVal = 1;

                        multiple = 2;

                }
                if (list.Count%mod != 0)
                {
                    return false;
                }
    
                int iNum = 0;//顺子的数量 例如：33334455，顺子数量为1
                int iWithNum = 0;//带牌的数量 例如：33334455，带牌数量为2
                int minVal = GMaxVal;
                List<int> listKey = new List<int>();
                foreach (var item in dicItem)
                {
                    if (item.Value != firstVal && item.Value != withVal)
                    {
                        return false;
                    }
                    if (item.Value == withVal)
                    {
                        iWithNum++;//累积带牌数量
                    }
                    if (item.Value == firstVal)
                    {
                        iNum++;//累积顺子数量
                        listKey.Add(item.Key);
                    }
                    if ((item.Key < minVal) && item.Value == firstVal)
                    {
                        minVal = item.Key;
                    }
                }
                if (iWithNum != iNum * multiple)
                {
                    return false;
                }
                if (listKey.Count >= 2)
                {
                    listKey.Sort((x, y) => x.CompareTo(y));
                    if (isInOrder(listKey) == false)
                    {
                        return false;
                    }
                }
                val = minVal;
                num = iNum;
                cardType = dealType;
                return true;
            }

这里连牌带牌有4种：3带1单，3带1对，4带2单，4带2对。

例如出牌：3333444455667788，判断出牌型为4带2对，牌值为3，顺子数量为2，带牌数量为4，满足顺子与带牌的倍数：带牌数4=顺子数2\*倍数2。
