＊＊＊＊＊高分求正则＊＊＊＊＊＊

[阿飞7587]

求一正则，要求实现：
如果url是:www.bj.com/p1a33c33d2f4g9h11m2/
通过正则能提取出: p1、a33、c33、d2、f4、g9、h11、m2

如果url是:www.bj.com/p1a33c33d2f4g9h11m2/?type=bb&fac=2&d=3
通过正则能提取也：p1、a33、c33、d2、f4、g9、h11、m2、type=bb、fac=2、d=3

需要注意：p1a33c33d2f4g9h11m2，字母占位符顺序不是固定的，也有可能
a33c33p1d2f4h11g9m2

[阿飞7587]

如果我要url重写，将"http://www.bj.com/p1a33c33d2f4g9h11m2/?type=bb&fac=2&d=3"; 中的p1a33c33d2f4g9h11m2/?type=bb&fac=2&d=3";给提取出来，如何写呢？ 比如： <rewrite url="^/sale/(此处正则如何写)$" to="~/index.aspx?placeholder=$1" />

大家帮助看下

上面的规则:<rewrite url="^/test/([\w\W]*)*?/?$" to="~/index.aspx?placeholder=$1" /> 对于字符串url:/test/p3m3h4t4o2d1c8z4n1u4/?pmin=0&pmax=99999&amin=0&amax=99999&near=&tag=3_2&key= 只能匹配到: p3m3h4t4o2d1c8z4n1u4/?pmin=0 ，&后面的都找不到了, 正则应该如何改进呢？

上面正则分组1可以正常匹配，虽然写的有点罗嗦

string pattern = @"^/test/([\w\W]*)*?/?$";
                string tempStr = "/test/p3m3h4t4o2d1c8z4n1u4/?pmin=0&pmax=99999&amin=0&amax=99999&near=&tag=3_2&key=";

                string result = Regex.Match(tempStr,pattern).Groups[1].Value;
                //p3m3h4t4o2d1c8z4n1u4/?pmin=0&pmax=99999&amin=0&amax=99999&near=&tag=3_2&key=

引用 2 楼 hjywyj 的回复:

高手！昨天写了半天终于找到了关于MatchCollection的Lambda的写法
