求个简单的正则表达式

net205 2011-09-29 10:15:16

var abc = new string[] { "news", "/news", "/news/", "/news/abc", "/news/abcdew/", "/news/abcd/test.aspx", "/news/add/abc.jpb", "/news/wew/news/"};

这样的字符串，我想匹配到news后面第一个斜线与第二个斜线之间的字符，结果应该是：
"news" -> 失败
"/news" -> 失败
"/news/" -> 失败
"/news/abc" -> 成功，groups[1]为 abc
"/news/abcdew/" -> 成功，groups[1]为 abcdew
"/news/abcd/test.aspx" -> 成功，groups[1]为 abcd
"/news/add/abc.jpb" -> 成功，groups[1]为 add
"/news/wew/news/" -> 成功，groups[1]为 wew

我目前使用的是/news/(.+?)(/\.)?和/news/(.+)?(/\.)?　，这2个都不行。

时隔10天lz在次现身

            List<string> list = new List<string> { "/gz", "/", "/gz?a=23", "/gz/abc.aspx", "/gz/abc.aspx?id=23", "/job/", "/job/?abc=233", "/job#top", "/job/?abc=233#top" };

            Regex reg = new Regex(@"(?<=/)[^#?/]+");

            foreach (string s in list)

                Console.WriteLine(reg.Match(s).Value);

还有类似这样的：
/job#top　　　　　-> 能匹配，得到job
/job/?abc=233#top -> 能匹配，得到job

谢谢各位.
huangwenquan123的可以, sunny906的不满足要求,其他的几个好像可以,没仔细测

现在需求有变,情况是:
Request.RawUrl获取url后面的地址,有很多种情况,类似:
/gz
/
/gz?a=23
/gz/abc.aspx
/gz/abc.aspx?id=23
/job/
/job/?abc=233

除了上面第二个以外,其他的都要能匹配,配置到的字符应该是gz或job

我写了一个不符合要求:/(.+)[/|\?]*
然后取match.Groups[1].Value

            string[] str = new string[] { "news", "/news", "/news/", "/news/abc", "/news/abcdew/", "/news/abcd/test.aspx", "/news/add/abc.jpb", "/news/wew/news/" };

            foreach (string s in str)

            {

                Match match = Regex.Match(s, "/news/(?:.)+", RegexOptions.IgnoreCase);

                Console.WriteLine(match.Value);

            }



///news/abc

///news/abcdew/

///news/abcd/test.aspx

///news/add/abc.jpb

///news/wew/news/

Regex reg = new Regex(@"^.*news\/([^\/]+)\/?.*$");

 Console.WriteLine(M.Groups[1].Value);
