C#正则表达式查找大写单词 [英] C# Regex to find uppercase word

问题描述

大家好，我遇到了正则表达式问题，希望有人可以帮助我.

我有一个字符串列表，每个字符串包含17个字母的大写单词，我需要从字符串中获取这个单词.
像这样的东西:

Hi everybody, I got a problem with regex, hope someone can help me.

I have a list of strings and each string contains uppercase word of 17 letters, I need to get this word from string.
Something like this:

string pattern = @"[A-Z0-9]{17}";
Regex regex = new Regex(pattern);
List<string> result = new List<string>();
foreach (string val in list)
{
    Match match = regex.Match(pattern);
    result.Add(match.Value);
}

推荐答案

我尝试过，其工作原理是:

I tried and its works:

   List<string> list = new List<string>();
   list.Add("ASD");
   list.Add("ASFsdsd");
   list.Add("adsASFsdsd");

   string pattern = @"[A-Z]{3}";
   Regex regex = new Regex(pattern);
   List<string> result = new List<string>();

   foreach (string val in list)
   {
       Match match = regex.Match(val);
       result.Add(match.Value);
   }

/*Result will be list with elements:
  ASD
  ASF
  ASF
*/

如果将3替换为17，它必须对您有用.

If you replace 3 with 17 it must work for you.
