用C#实现模拟双色球中奖控制台应用程序

1. 前言

其实这是我在大一第一学期CSharp的课程设计，要求编写一个模拟双色球彩票的控制台应用程序，用以实现简单的模拟选购彩票。

但最近我重新看我的博客时感觉之前写的代码还是有很多不足之处，比如变量的命名，方法的命名，整体代码风格等差强人意，毕竟是入门是写的代码，所以今天稍微修改一下，让命名更规范，注释更明确。当然，更重要的还是：不是吧代码拿来即用，而是让刚开始入门的小伙伴能够快速地对编程感兴趣，对.net平台感兴趣，对CSharp这门语言感兴趣,我们大家共同把国内的.net发展起来。

1.1 你会学到什么？

简单地运用CSharp语言和.net平台，如变量、方法、类、数组、字典、系统函数、规范的注释、控制台输出、文件的读写、程序怎样设计等。

1.2 开发环境或运行环境

1. Win10或Win11系统，Visual Studio 2022 开发环境；
2. .net6，CSharp10；

2. 程序设计 2.1 流程图

2.2 有哪些功能？

1. 产生模拟奖池；
2. 生成自定义购号记录；
3. 打印数据，读取数据；
4. 界面输出优化；
5. 保护用户隐私；
6. 程序结束后可继续查看中奖记录等。

2.3 运行展示 2.3.1 双色球规则

2.3.2 充值或提现

2.3.3 自动购号

自动购号在去重后会自动排序展示出来。

2.3.4 手动购号

可以看到，手动购号比系统购号稍微复杂了一点点，会有多次范围检测和重复检测，并且还要提示哪个球重复……完成购号后，自动购号和手动购号的记录就会在程序运行目录保存。

打开是这样的：

其实，数据保存方法经过了多次设计，最开始只是为了记录，后来做到开奖时不易拆分，一次次改进而来。设计过程如下：

====第1次设计====
用普通数据记录
第【01】注：红色球：01 02 03 04 05 06 蓝色球：07	【系统购号】时间：2019.06.12 22:02:01
第【02】注：红色球：06 14 15 22 29 32 蓝色球：11	【手动购号】时间：2019.06.12 22:02:07
====第2次设计====
去掉固定字符
01_01_02_03_04_05_06_07_系统购号_2019.06.12 22:02:01
02_06_14_15_22_29_32_11_手动购号_2019.06.12 22:02:07
====第3次设计====
用标记值 _
01_01_02_03_04_05_06_07_2019.06.12 22:02:01
02_06_14_15_22_29_32_11_2019.06.12 22:02:07
====第4次设计====
用标记值 N R B T
N01R020615182426B14T2022-05-02 下午 11:51:55
N02R011316172426B12T2022-05-02 下午 11:52:18

2.3.5 开奖

开奖时会先检测是否有购号记录：没有记录对本程序来说开奖的意义不大，就不开奖；有开奖记录会产生开奖号码，并产生模拟奖池和模拟奖池累计奖金，从而产生奖金总额。

开奖后，按照自动购号、手动购号的次序进行对比购号记录，有中奖时，记录中将号码和相应的中奖金额便于查看，然后将奖金自动发放到账户余额。之后，删除之前的所有购号记录。

具体信息如下：

2.3.6 开奖后的操作

开奖后你可以继续选择充值、提现、购号等。
