Question

公司名称变化很大，所以我添加了很多或条件。

也许有人用正则表达式来做这件事吗？

我将所需的值存储在不同的组中。

感谢您的帮助！

我只在文本中添加了一部分，完整的文字是大的！希望这对Futur有帮助！链接具有完整的列表。

Answer 1

您的数据与第15项始终是公司名称非常一致：

List<string> items = new List<string>();
int count = 0;
foreach (string s in yourData.Split(';')) {
  count++;
  if (count == 15) {
    items.Add(s);
    count = 1;
  }
}
MessageBox.Show(string.Join(Environment.NewLine, items.ToArray()));

Answer 2

这个正则表达式，我认为，至少在眼睛上更容易（恐怖！），似乎解析数据好了：

(?<company>.*?);(?<prefix>.*?);.(?<number>\d*?);(?<code1>.*?);(?<code2>.*?);(?<code3>.*?);.*$

*我们利用数据用分号很好地划分的事实，我们想要第一个＆＃39;然而很多＆＃39;字段 - 每个连续和（几乎）相同的命名匹配组表示的字段。

.*?与＆＃34;贪婪＆＃34;相同版本：.*，但它从匹配none（而不是全部）开始，然后根据需要匹配更多。

Answer 3

它是公司列表，日期（可选），数字（可选）和bool值 - 全部由＆＃39;;＆＃39;

分隔

所以...按＆＃39 ;;＆＃39;拆分，然后过滤一个简单的正则表达式，以排除已知的非公司名称值：

Regex excludeRegex = new Regex(@"[\d\.]+|true|false", RegexOptions.IgnoreCase);
string dataString = "asd;sdfsdf;f fff; 123.231; true; abb";

List<string> companies = dataString.Split(';',StringSplitOptions.RemoveEmptyEntries)
    .Select(c=>c.Trim())
    .Where(c=>!excludeRegex.IsMatch(c))
    .Distinct()
    .ToList();

Answer 4

看起来像一个模式。

(?m)^\s*([^;]+?)\s*;\s*([^;]+?)\s*;\s*([^;]+?)\s*;\s*([^;]+?)\s*;\s*([^;]+?)\s*;\s*([^;]+?)\s*;(?=.*?(?:true|false);)

 (?m)
 ^ \s* 
 ( [^;]+? )                    # (1)
 \s* ; \s* 
 ( [^;]+? )                    # (2)
