[英]Whats wrong in my regex pattern?
I'm wrote a pattern 我写了一个模式
string pattern2 = @"(?[<ports>\w+,*]*)";
This pattern should help parse string of next format 此模式应有助于解析下一种格式的字符串
[port1, port2_4][portN_][port,port2,port5,p0_p1]
After parsing I'm want to have array of strings: 解析后,我想要一个字符串数组:
1. port1, port2_4
2. portN_
3. port, port2,port5,p0_p1
this will work... 这将工作...
(?<=\[)(?<ports>.*?)(?=\])
(?<=\\[)
prefix of [
but dont include in match (?<=\\[)
的前缀[
但不包括在匹配 (?<ports>.*?)
named capture "ports" match anything non greedy ( as little as possible) (?<ports>.*?)
命名的捕获“端口”与任何非贪婪的匹配(尽可能少) (?=\\])
suffix of ]
but don't include it in the match (?=\\])
的后缀]
,但不包括它在比赛中 code :- 代码:-
Regex regex = new Regex(@"(?<=\[)(?<ports>.*?)(?=\])");
var m = regex.Matches("[port1, port2_4][portN_][port,port2,port5,p0_p1]");
foreach (var p in m)
{
Console.WriteLine(p);
}
output : 输出:
port1, port2_4
portN_
port,port2,port5,p0_p1
