提取字符串 C#

Question

有如下一段英文， 我如何写一个正则表达式提取出

access-list 110689 extended permit ip any object-group OA

access-list 110689 extended permit ip any object-group ERP

access-list 110689 extended permit ip any object-group QQ

这三句话放入List<string>里面。

请问各位大侠有好的方法吗？

access-list 110689 extended permit ip any object-group OA

access-list 110689 extended permit ip any object-group ERP

access-list 110689 extended permit ip any object-group QQ

dgvpn(config)# no group-policy 11068966 attributes

Answer 1

正则表达式如下：

access-list \d+ extended permit ip any object-group \w+

其实就是只需要把中间的数字和最后的字母用正则匹配上就行了

你好,

正如懒得勤快所说， 使用正则表达式来做，下面是一个完整的例子，你可以参考一下：

var test = @"login as: aa
                        admin@172.220.22.38's password:bb
                        User admin logged in to dgvpn 
                        dgvpn> enable
                        Password:cc
                        dgvpn# configure terminal
                        dgvpn(config)# show running-config access-list 110689
                        access-list 110689 extended permit ip any object-group OA

                        access-list 110689 extended permit ip any object-group ERP

                        access-list 110689 extended permit ip any object-group QQ

                        dgvpn(config)# no group-policy 11068966 attributes";

            string regText = @"access-list \d+ extended permit ip any object-group \w+";
            Regex regex = new Regex(regText);
            Match result = regex.Match(test);

            MatchCollection mc = regex.Matches(test);
            List<string> list = new List<string>();
            foreach (var item in mc)
            {
                list.Add(item.ToString());
            }

Best regards,
