什么是正则表达式在.NET命名捕获组？

问题描述

我挣扎了正则表达式模式，将拉出从文本字符串到命名组。

A（有些武断）的例子最能说明什么，我想要的目的。

 字符串输入=
    玛丽·安妮一直在949宾果游戏比赛的最后于星期二24/04/2012她与数赢：4，6，11，16，19，27，45;

字符串模式=
    @（LT;人＆GT; \ W +）一直到（小于？NumberOfGames＆GT;？\ d +）宾果游戏比赛的最后的。（LT;节＆GT; ...？）（＆LT;日期取代。 ？..），她赢得的数字：？（小于号＆GT; ...）？

正则表达式的regex ​​=新的正则表达式（模式）;
VAR匹配= regex.Match（输入）;

串人= match.Groups [人]值。
字符串noOfGames = match.Groups [NumberOfGames]值。
字符串日= match.Groups [日]值。
字符串日= match.Groups [日期]值。
一串数字= match.Groups [编号]值。
 

我似乎无法获得正则表达式的工作，但我认为上述解释的不够好。基本上我需要得到人的名字，游戏的数量等。

任何人都可以解决这个问题，并解释他们的工作出实际的正则表达式？

解决方案

 字符串模式= @（LT;人＆GT; [\ w] +）一直到（小于？; NumberOfGames＆GT; \ D +）赌博游戏\最后是在（小于？日＆GT; \ w +）（小于日期和GT; \ D \ D / \ D \ D / \ D {4}）\她的赢数字：（？＆LT;数字＆GT; *？）$;
 

其他的帖子都提到了如何拔出组，但此正则表达式您输入相匹配。

I'm struggling with a regex pattern that will pull out text from a string into named groups.

A (somewhat arbitrary) example will best explain what I'm trying to achieve.

string input =
    "Mary Anne has been to 949 bingo games. The last was on Tue 24/04/2012. She won with the Numbers: 4, 6, 11, 16, 19, 27, 45";

string pattern =
    @"(?<Person>\w+?) has been to (?<NumberOfGames>\d+?) bingo games. The last was on (?<Day>...?) (?<Date>...?). She won with the Numbers: (?<Numbers>...?)";

Regex regex = new Regex(pattern);
var match = regex.Match(input);

string person = match.Groups["Person"].Value;
string noOfGames = match.Groups["NumberOfGames"].Value;
string day = match.Groups["Day"].Value;
string date = match.Groups["Date"].Value;
string numbers = match.Groups["Numbers"].Value;

I can't seem to get the regex pattern to work, but i think the above explains it well enough. Essentially i need to get the person name, the number of games etc.

Can anyone solve this and explain the actual regex pattern they worked out?

解决方案

 string pattern = @"(?<Person>[\w ]+) has been to (?<NumberOfGames>\d+) bingo games\. The last was on (?<Day>\w+) (?<Date>\d\d/\d\d/\d{4})\. She won with the Numbers: (?<Numbers>.*?)$";

Other posts have mentioned how to pull out the groups, but this regex matches on your input.
