灯具不会添加到文本文件中

Question

我目前正在开展一个篮球模拟游戏的项目，我在为将要玩的游戏生成灯具时遇到问题，而且我完全忘记了导致问题的原因。

错误列表中没有出现错误，但由于某些原因应该生成灯具时，我认为发生了无限循环，但我不确定导致问题的原因。

我已经分离了算法中使用的数组以及从下面算法中添加到文本文件的初始文件：http://pastebin.com/cLXi0Hm3因为我觉得它会占用太多空间。

以下是创建这些灯具的算法：

public static void Fixtures()
{
    List<string> SouthwestFixtures = new List<string>(); // Create a new list to store the games
    while (SouthwestFixtures.Count < 410) // Whilst length of fixtures is less than 410
    {
        /// <summary>
        /// Southwest Division Fixtures
        /// </summmary>

        Random rnd = new Random(); // Generate a new random
        string SWTeam1 = Arrays.WCSouthwest[rnd.Next(Arrays.WCSouthwest.Length)]; // Select random home team
        string SWTeam2 = Arrays.WCSouthwest[rnd.Next(Arrays.WCSouthwest.Length)]; // Select random away team
        if (SWTeam1 == SWTeam2) // If they are the same teams
        {
            while (SWTeam1 == SWTeam2) // whilst they are equal to eachother
            {
                string newteam = Arrays.WCSouthwest[rnd.Next(Arrays.WCSouthwest.Length)];
                SWTeam2 = newteam; // generate new away team
            }
        }

        string fixture = string.Format("{0} v {1}", SWTeam1, SWTeam2); // convert it to a string               


        for (int i = 0; i <= 40; i++) // whilst i is 0
        {
            if (SouthwestFixtures.Contains(fixture)) // if fixture is already in fixtures stop
            { break; }
            else
            {
                SouthwestFixtures.Add(fixture);
                SouthwestFixtures.Add(fixture);
            } // add it
        }
        /// <summary>
        /// 4 Games Against 6 Out of Division Teams In Same Conference
        /// </summary>

        var WCNWList = Arrays.WCNorthwest.ToList();
        var WCPList = Arrays.WCPacific.ToList();
        var WCCombined = WCNWList.Concat(WCPList);
        var WCCombined1 = WCCombined.ToList();
        List<string> WCCombined2 = new List<string>(4);

        for (int i = WCCombined1.Count(); i > 6; i--)
        {
            int WCRemoveTeam = rnd.Next(WCCombined1.Count());
            WCCombined2.Add(WCCombined1[WCRemoveTeam]);
            WCCombined1.RemoveAt(WCRemoveTeam);
        }

        var WCCombined1Array = WCCombined1.ToArray();
        var WCCombined2Array = WCCombined2.ToArray();

        string SWTeam = Arrays.WCSouthwest[rnd.Next(Arrays.WCSouthwest.Length)]; // Select random home team
        string WCTeam = WCCombined1Array[rnd.Next(WCCombined1Array.Length)]; // Select random away team


        string fixturehome = string.Format("{0} v {1}", SWTeam, WCTeam); // convert it to a string
        string fixtureaway = string.Format("{0} v {1}", WCTeam, SWTeam);

        for (int i = 0; i <= 30; i++) // whilst i is 0
        {
            if (SouthwestFixtures.Contains(fixturehome) || SouthwestFixtures.Contains(fixtureaway)) // if fixture is already in fixtures break
            { break; }
            else
            {
                SouthwestFixtures.Add(fixturehome);
                SouthwestFixtures.Add(fixturehome);
                SouthwestFixtures.Add(fixtureaway);
                SouthwestFixtures.Add(fixtureaway);
            } // add it
        }

        /// <summary>

        string WCTeam2 = WCCombined2Array[rnd.Next(WCCombined2Array.Length)]; //Grab team from list of teams to play 3 games against

        string fixturehome2 = string.Format("{0} v {1}", SWTeam, WCTeam2); // convert it to a string

        {

            {
                SouthwestFixtures.Add(fixturehome2);

            }
            int homeoraway = rnd.Next(1, 2);
            if (homeoraway == 1)
            {
                SouthwestFixtures.Add(fixturehome2);
            }
            else
            {
                SouthwestFixtures.Add(fixtureaway2);
            }
        }
        /// <summary>

        /// </summary>

        string ECTeam = Arrays.ECTeams[rnd.Next(Arrays.ECTeams.Length)]; // Select random away team

        string fixtureh = string.Format("{0} v {1}", SWTeam, ECTeam); // convert it to a string
        string fixturea = string.Format("{0} v {1}", ECTeam, SWTeam);


        for (int i = 0; i <= 75; i++) // whilst i is 0
        {
            if (SouthwestFixtures.Contains(fixtureh) || SouthwestFixtures.Contains(fixturea)) // if fixture is already in fixtures break
            { break; }
            else
            {
                SouthwestFixtures.Add(fixtureh);
                SouthwestFixtures.Add(fixturea);
            } // add it
        }


    } // loop through till it is done
}

我很确定当它产生最后两个夹具部分时出现问题（对阵4支球队的3场比赛以及东部会议比赛之前的所有事情，但我仍然无法弄清楚它出错的地方）

如果有人帮忙指出哪里出错了，我将不胜感激。
