C#使用随机数模拟英雄联盟S13瑞士轮比赛

 瑞士轮赛制的由来

瑞士制：又称积分循环制，最早出现于1895年在瑞士苏黎世举办的国际象棋比赛中，故而得名。其基本原则是避免种子选手一开始就交锋、拼掉，是比较科学合理、用得最多的一种赛制；英语名称为Swiss System。

欲通过瑞士轮的考验进入淘汰赛，那么需要在此阶段拿下三场胜利，反之遭遇三场失利就会被淘汰。瑞士轮阶段的比赛，包含了五个轮次的比赛，每轮的比赛对阵都由抽签来决定。

第一轮有8场比赛：比赛全部为BO1（同赛区规避），这8场比赛结束之后，16支队伍会按照胜负情况分为两组，1-0战绩的队伍8支，0-1战绩的队伍8支。

第二轮同样也是8场BO1的比赛：抽签后的对阵原则是1-0战绩的队伍和1-0战绩的队伍打（也就是第一轮的胜者打胜者），0-1战绩的队伍和0-1战绩的队伍打（也就是第一轮的败者打败者）。此轮比赛结束后，会有4支2-0的队伍，4支0-2的队伍，8支1-1的队伍。

第三轮的比赛就显得复杂一些了，因为第三轮就会诞生率先晋级淘汰赛以及不得不遗憾出局的队伍了：关乎淘汰和晋级的比赛都将是BO3的设定，2-0的队伍打2场BO3， 1-1的队伍打4场BO1，0-2的队伍打2场BO3。第三轮比赛结束之后，会宣告2支队伍以3-0的成绩晋级淘汰赛，2支队伍以0-3的成绩遗憾出局。

第四轮的比赛最为残酷：2-1的队伍打3场BO3，胜者晋级淘汰赛，1-2的队伍打3场BO3。比赛结束后晋级3支队伍，淘汰3支队伍；留在场上的6支队伍是全部都会是2-2的胜负场情形。

第五轮的比赛是晋级淘汰赛的最后机会，2-2的队伍们打3场BO3，晋级3支队伍淘汰3支队伍。

综上所述：通过五个轮次的比赛，8支队伍得以晋级，8支队伍遭遇淘汰。

一文读懂2023英雄联盟全球总决赛瑞士轮赛制

我们新建一个仿真窗体应用程序LOL_S13Demo。

将默认的Form1重命名为FormLOL_S13

一、新建图片文件夹TeamFlagImage，将各个战队图标导入，并设置为始终复制

二、然后新建随机数类RandomUtil，源程序如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace LOL_S13Demo
{public class RandomUtil {private static int[] nums;private static Random rand = new Random();/// <summary>/// 初始化数组索引/// </summary>/// <param name="indexArray"></param>public static void Init(int[] indexArray){nums = indexArray;}/// <summary>/// 洗牌算法,洗牌算法的时间复杂度是 O(N)/// 第一次有N种可能，第二次有N-1种可能，第三次有N-2种可能/// ...最后一次只有一种可能/// </summary>/// <returns></returns>public static int[] Shuffle(){int n = nums.Length;int[] copy = new int[n];Array.Copy(nums, copy, n);for (int i = 0; i < n; i++){// 生成一个 [i, n-1] 区间内的随机数int r = i + rand.Next(n - i);// 交换 nums[i] 和 nums[r],即获取第r个数【放到第i个位置】Swap(copy, i, r);}return copy;}/// <summary>/// 交换数组两个数的值/// </summary>/// <param name="nums"></param>/// <param name="i"></param>/// <param name="j"></param>private static void Swap(int[] nums, int i, int j){int temp = nums[i];nums[i] = nums[j];nums[j] = temp;}}
}

三、新建战队类Team，属性如下：

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace LOL_S13Demo
{/// <summary>/// 英雄联盟S13参赛战队/// </summary>class Team{/// <summary>/// 战队名称/// </summary>public string TeamName { get; set; }/// <summary>/// 战队胜率/// </summary>public decimal WinningRatio { get; set; }/// <summary>/// 战队图标/// </summary>public Image TeamFlag { get; set; }}
}

四、新建自定义控件UcTeam，设计器源码如下：

文件 UcTeam.designer.cs

using System.Windows.Forms;namespace LOL_S13Demo
{partial class UcTeam{/// <summary> /// 必需的设计器变量。/// </summary>private System.ComponentModel.IContainer components = null;/// <summary> /// 清理所有正在使用的资源。/// </summary>/// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>protected override void Dispose(bool disposing){if (disposing && (components != null)){components.Dispose();}base.Dispose(disposing);}#region 组件设计器生成的代码/// <summary> /// 设计器支持所需的方法 - 不要修改/// 使用代码编辑器修改此方法的内容。/// </summary>private void InitializeComponent(){this.panel2 = new System.Windows.Forms.Panel();this.lblWinningRatio = new System.Windows.Forms.Label();this.lblTeamName = new System.Windows.Forms.Label();this.picTeamFlag = new System.Windows.Forms.PictureBox();this.panel2.SuspendLayout();((System.ComponentModel.ISupportInitialize)(this.picTeamFlag)).BeginInit();this.SuspendLayout();// // panel2// this.panel2.Controls.Add(this.lblWinningRatio);this.panel2.Controls.Add(this.lblTeamName);this.panel2.Controls.Add(this.picTeamFlag);this.panel2.Location = new System.Drawing.Point(3, 2);this.panel2.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.panel2.Name = "panel2";this.panel2.Size = new System.Drawing.Size(257, 127);this.panel2.TabIndex = 2;// // lblWinningRatio// this.lblWinningRatio.AutoSize = true;this.lblWinningRatio.ForeColor = System.Drawing.Color.Green;this.lblWinningRatio.Location = new System.Drawing.Point(155, 5);this.lblWinningRatio.Name = "lblWinningRatio";this.lblWinningRatio.Size = new System.Drawing.Size(29, 12);this.lblWinningRatio.TabIndex = 5;this.lblWinningRatio.Text = "胜率";// // lblTeamName// this.lblTeamName.AutoSize = true;this.lblTeamName.ForeColor = System.Drawing.Color.Blue;this.lblTeamName.Location = new System.Drawing.Point(21, 5);this.lblTeamName.Name = "lblTeamName";this.lblTeamName.Size = new System.Drawing.Size(29, 12);this.lblTeamName.TabIndex = 4;this.lblTeamName.Text = "战队";// // picTeamFlag// this.picTeamFlag.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Zoom;this.picTeamFlag.Location = new System.Drawing.Point(21, 21);this.picTeamFlag.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.picTeamFlag.Name = "picTeamFlag";this.picTeamFlag.Size = new System.Drawing.Size(214, 106);this.picTeamFlag.TabIndex = 3;this.picTeamFlag.TabStop = false;// // UcTeam// this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;this.Controls.Add(this.panel2);this.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.Name = "UcTeam";this.Size = new System.Drawing.Size(262, 131);this.panel2.ResumeLayout(false);this.panel2.PerformLayout();((System.ComponentModel.ISupportInitialize)(this.picTeamFlag)).EndInit();this.ResumeLayout(false);}#endregionprivate Panel panel2;public PictureBox picTeamFlag;public Label lblWinningRatio;public Label lblTeamName;}
}

UcTeam.cs源程序如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace LOL_S13Demo
{public partial class UcTeam : UserControl{public UcTeam(){InitializeComponent();}}
}

五、新建战队与操作比赛相关类TeamUtil

TeamUtil.cs源程序如下：

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace LOL_S13Demo
{internal class TeamUtil{/// <summary>/// 所有参赛的世界杯战队/// </summary>public static List<Team> ListTeam = new List<Team>();/// <summary>/// 初始化世界杯各个参赛战队/// </summary>public static void InitTeam() {ListTeam.Clear();AddTeam(new Team(){TeamName = "JDG",WinningRatio = 90,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\JDG.jpg")});AddTeam(new Team(){TeamName = "LNG",WinningRatio = 85,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\LNG.jpg")});AddTeam(new Team(){TeamName = "BLG",WinningRatio = 80,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\BLG.jpg")});AddTeam(new Team(){TeamName = "WBG",WinningRatio = 75,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\WBG.jpg")});AddTeam(new Team(){TeamName = "GEN",WinningRatio = 90,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\GEN.jpg")});AddTeam(new Team(){TeamName = "T1",WinningRatio = 85,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\T1.jpg")});AddTeam(new Team(){TeamName = "KT",WinningRatio = 80,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\KT.jpg")});AddTeam(new Team(){TeamName = "DK",WinningRatio = 75,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\DK.jpg")});AddTeam(new Team(){TeamName = "FNC",WinningRatio = 80,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\FNC.jpg")});AddTeam(new Team(){TeamName = "BDS",WinningRatio = 70,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\BDS.jpg")});AddTeam(new Team(){TeamName = "C9",WinningRatio = 75,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\C9.jpg")});AddTeam(new Team(){TeamName = "G2",WinningRatio = 70,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\G2.jpg")});AddTeam(new Team(){TeamName = "GAM",WinningRatio = 75,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\GAM.jpg")});AddTeam(new Team(){TeamName = "MAD",WinningRatio = 75,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\MAD.png")});AddTeam(new Team(){TeamName = "NRG",WinningRatio = 65,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\NRG.png")});AddTeam(new Team(){TeamName = "TL",WinningRatio = 85,TeamFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "TeamFlagImage\\TL.png")});}/// <summary>/// 添加一个战队/// </summary>/// <param name="Team"></param>public static void AddTeam(Team Team) {ListTeam.Add(Team);}/// <summary>/// 两个匹配的战队进行比赛，根据胜率，进行随机，返回胜利的战队/// 胜利法则如下：先随机出一个胜率之和之间的随机数，/// 如果随机数小于【最小数的2倍】并且是奇数，则认为 胜率低的战队胜利，否则 胜率高的战队胜利/// </summary>/// <param name="tuple">参赛战队</param>/// <param name="failTeam">失败战队</param>/// <returns></returns>public static Team SoccerGame(Tuple<Team, Team> tuple, out Team failTeam, out int randomNumber) {failTeam = tuple.Item2;randomNumber = -1;if (tuple == null || tuple.Item1 == null) {throw new Exception("世界比赛无参赛的战队或者第一个参赛战队不存在");}if (tuple.Item2 == null) {//无第二个世界参赛战队，直接躺赢【对奇数个参赛战队的特殊处理】return tuple.Item1;}decimal minWinningRatio = Math.Min(tuple.Item1.WinningRatio, tuple.Item2.WinningRatio);Team bigWin = null;//高胜率Team smallWin = null;//低胜率if (tuple.Item1.WinningRatio < tuple.Item2.WinningRatio){bigWin = tuple.Item2;smallWin = tuple.Item1;}else{bigWin = tuple.Item1;smallWin = tuple.Item2;}int total = (int)(tuple.Item1.WinningRatio + tuple.Item2.WinningRatio);Random random = new Random(Guid.NewGuid().GetHashCode());//先随机出一个胜率之和之间的随机数randomNumber = random.Next(total);if (randomNumber < minWinningRatio * 2 && (randomNumber & 1) != 0) {//如果随机数小于【最小数的2倍】并且是奇数，则认为 胜率低的战队胜利，否则 胜率高的战队胜利failTeam = bigWin;return smallWin;}failTeam = smallWin;return bigWin;}}
}

六、窗体FormLOL_S13的设计器程序如下：

FormLOL_S13.designer.cs

using System.Windows.Forms;namespace LOL_S13Demo
{partial class FormLOL_S13{/// <summary>/// Required designer variable./// </summary>private System.ComponentModel.IContainer components = null;/// <summary>/// Clean up any resources being used./// </summary>/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>protected override void Dispose(bool disposing){if (disposing && (components != null)){components.Dispose();}base.Dispose(disposing);}#region Windows Form Designer generated code/// <summary>/// Required method for Designer support - do not modify/// the contents of this method with the code editor./// </summary>private void InitializeComponent(){this.btnStart = new System.Windows.Forms.Button();this.btnRefresh = new System.Windows.Forms.Button();this.rtxtDisplay = new System.Windows.Forms.RichTextBox();this.pnlTeam = new System.Windows.Forms.Panel();this.SuspendLayout();// // btnStart// this.btnStart.Location = new System.Drawing.Point(871, 5);this.btnStart.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.btnStart.Name = "btnStart";this.btnStart.Size = new System.Drawing.Size(152, 28);this.btnStart.TabIndex = 0;this.btnStart.Text = "开始比赛 直到 决出冠军";this.btnStart.UseVisualStyleBackColor = true;this.btnStart.Click += new System.EventHandler(this.btnStart_Click);// // btnRefresh// this.btnRefresh.Location = new System.Drawing.Point(1065, 5);this.btnRefresh.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.btnRefresh.Name = "btnRefresh";this.btnRefresh.Size = new System.Drawing.Size(133, 28);this.btnRefresh.TabIndex = 1;this.btnRefresh.Text = "刷新重新随机分配";this.btnRefresh.UseVisualStyleBackColor = true;this.btnRefresh.Click += new System.EventHandler(this.btnRefresh_Click);// // rtxtDisplay// this.rtxtDisplay.Location = new System.Drawing.Point(854, 37);this.rtxtDisplay.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.rtxtDisplay.Name = "rtxtDisplay";this.rtxtDisplay.Size = new System.Drawing.Size(378, 761);this.rtxtDisplay.TabIndex = 2;this.rtxtDisplay.Text = "";// // pnlTeam// this.pnlTeam.AutoScroll = true;this.pnlTeam.Location = new System.Drawing.Point(1, 1);this.pnlTeam.Name = "pnlTeam";this.pnlTeam.Size = new System.Drawing.Size(847, 797);this.pnlTeam.TabIndex = 3;// // FormLOL_S13// this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;this.ClientSize = new System.Drawing.Size(1255, 802);this.Controls.Add(this.pnlTeam);this.Controls.Add(this.rtxtDisplay);this.Controls.Add(this.btnRefresh);this.Controls.Add(this.btnStart);this.Margin = new System.Windows.Forms.Padding(3, 2, 3, 2);this.Name = "FormLOL_S13";this.Text = "英雄联盟S13赛季_瑞士轮随机排名模拟器";this.Load += new System.EventHandler(this.FormTeam_Load);this.ResumeLayout(false);}#endregionprivate Button btnStart;private Button btnRefresh;private RichTextBox rtxtDisplay;private Panel pnlTeam;}
