1 雙色球隨機選號器界面設計

1.1 雙色球隨機選號器界面設計

效果如下：

2 雙色球隨機選號器代碼實現

2.1 項目文件結構

項目文件結構如下：

2.2 代碼實現

DoubleChromosphere.cs：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;namespace xiketang.com.LotteryPro {/// <summary>/// 雙色球類/// /// 作用：主要是用來封裝數據/// </summary>public class DoubleChromosphere{//public string Red1Number { get; set; }//public string Red2Number { get; set; }//public string Red3Number { get; set; }//public string Red4Number { get; set; }//public string Red5Number { get; set; }//public string Red6Number { get; set; }//public string Blue7Number { get; set; }請大家自學完課程后，可以嘗試分開保存兩種球的數字//public List<string> RedNumbers { get; set; }//public List<string> BlueNumbers { get; set; }//今天我們授課：把紅色球和藍色球放到一塊public List<string> Numbers { get; set; }} }

Selector.cs：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;namespace xiketang.com.LotteryPro {/// <summary>/// 選號器類/// </summary>public class Selector{//紅色球池public List<string> RedNumberList { get; set; }//藍色球池public List<string> BlueNumberList { get; set; }//存儲選擇的號碼public List<DoubleChromosphere> SelectedNums { get; set; } = new List<DoubleChromosphere>();private Random random = new Random();//隨機數生成器（只在本類內部使用）/// <summary>/// 構造方法：初始化球池的數字/// </summary>public Selector(){RedNumberList = new List<string>{"01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31","32","33"};BlueNumberList = new List<string>{"01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16"};}/// <summary>/// 生成7個隨機不同的號碼/// </summary>/// <returns></returns>public List<string> CreateRandomNum(){List<string> numList = new List<string>();//生成6個紅色球while (true){if (numList.Count == 6) break;//如果隨機選取了6個數字了，則退出循環string num = RedNumberList[random.Next(33)];if (numList.Contains(num)) continue;//如果是重復的數字，則重新隨機抽取else{numList.Add(num);} }//生成一個藍色球numList.Add(BlueNumberList[random.Next(16)]);return numList;}//打印、遠程保存等（我們在深入的VIP系統學習中再講解...)//這些方法，都會用到我們所保存的《已選擇號碼》} }
