C#使用随机数模拟器来模拟世界杯排名(二)_斯内科的博客-CSDN博客
上一篇我们使用随机数匹配比赛的世界杯国家，
这一篇我们使用随机数以及胜率模拟器 决赛出 世界杯冠军、亚军。
我们在主界面 新增按钮【开始比赛 直到 决出冠军】和【刷新重新随机分配】
面板Panel：pnlWorldCup
按钮：【开始比赛 直到 决出冠军】btnStart
按钮：【刷新重新随机分配】btnRefresh
富文本控件RichTextBox：rtxtDisplay
窗体FormWorldCupRanking设计如图：
更新CountryUtil.cs，增加SoccerGame方法，用于获取两个参赛世界杯国家胜利的一方。
CountryUtil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 WorldCupRankingDemo
{
internal class CountryUtil
{
///
/// 所有参赛的世界杯国家
///
public static List ListWorldCup = new List();
///
/// 初始化世界杯各个参赛国家
///
public static void InitCountry()
{
ListWorldCup.Clear();
AddCountry(new Country()
{
CountryName = "法国",
WinningRatio = 90,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\法国.png")
});
AddCountry(new Country()
{
CountryName = "阿根廷",
WinningRatio = 95,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\阿根廷.png")
});
AddCountry(new Country()
{
CountryName = "巴西",
WinningRatio = 98,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\巴西.png")
});
AddCountry(new Country()
{
CountryName = "荷兰",
WinningRatio = 80,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\荷兰.png")
});
AddCountry(new Country()
{
CountryName = "克罗地亚",
WinningRatio = 70,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\克罗地亚.png")
});
AddCountry(new Country()
{
CountryName = "葡萄牙",
WinningRatio = 75,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\葡萄牙.png")
});
AddCountry(new Country()
{
CountryName = "摩洛哥",
WinningRatio = 65,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\摩洛哥.png")
});
AddCountry(new Country()
{
CountryName = "英格兰",
WinningRatio = 85,
NationalFlag = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "NationalFlagImage\\英格兰.png")
});
}
