用C#开发的双色球走势图(一)

      首先声明,个人纯粹无聊之作,不作商业用途。

      我相信每个人都拥有一个梦想那就是有朝一日能中500W,这个也一直是我的梦想,并默默每一期双色球或多或少要贡献自己一点点力量,本人并不属于那种铁杆的彩票迷,每次都是纯粹娱乐而已,因为深知这个中奖的概率太低了,每一次买也是随机而已,运气好的话还能中个五块钱,运气不好的话随机买五注,甚至一个号码也中不到,每次去购买双色球都会看到走势图,所以个人最近就花了一点时间在这个上面,进行了一番研究,现将研究成果写出来,供园友一起探讨,愿各位早日中500W。

       双色球开奖数据个人也是从某网站抓取的,不保存到数据库,根据这些原始数据去分析双色球的走势,如有基本走势图、红球三分区走势图、红球四分区走势图、红球七分区走势图、红球连号走势图、和值走势图、篮球综合走势图和历史同期等等组成。

        首先介绍双色球原始数据是如何获取的?这个对于各位来说都比较简单,就是获取HTML源码,根据HTML去提取相关信息。

获取网页上数据后,再提取HTML相关信息,提取代码如下:

 1 /// <summary>
 2         /// 循环解析Tr
 3         /// </summary>
 4         /// <param name="wnRepo"></param>
 5         /// <param name="content"><tbody></tbody>之间的内容</param>
 6         private void ResolveTr(string content)
 7         {
 8             listWinNo.Clear();
 9             //--
10             string trContent = string.Empty;
11             WinNo wn = null;
12             Regex regex = new Regex("<tr>");
13             //在<tbody></tbody>之间的内容搜索所有匹配<tr>的项
14             MatchCollection matches = regex.Matches(content);
15             foreach (Match item in matches)
16             {
17                 wn = new WinNo();
18                 //如果当前匹配项的下一个匹配项的值不为空
19                 if (!string.IsNullOrEmpty(item.NextMatch().Value))
20                 {
21                     trContent = content.Substring(item.Index, item.NextMatch().Index - item.Index);
22                 }
23                 //最后一个<tr>的匹配项
24                 else
25                 {
26                     trContent = content.Substring(item.Index, content.Length - item.Index);
27                 }
28                 ResolveTd(ref wn, trContent);
29                 //wnRepo.Insert(wn);
30                 listWinNo.Add(wn);
31             }
