1、匹配外层中括号

(?i)(?<=\[)(.*)(?=\])

参照:(http://bbs.csdn.net/topics/380239087)

(http://book.51cto.com/art/200801/64658.htm)

2、匹配手机和身份证

Regex rgPHPone = new Regex(@"[1][3,4,5,8]\d{9}",RegexOptions.IgnoreCase | RegexOptions.Multiline);
Regex rgID = new Regex(@"\d{17}[a-zA-Z]|\d{18}|\d{15}");

或者:

身份证:^[1-9]\d{5}[1-9]\d{3}((0\d)|(1[0-2]))(([0|1|2]\d)|3[0-1])((\d|x|X){4})$ 手机：^(0|86|17951)?(13[0-9]|15[012356789]|17[678]|18[0-9]|14[57])[0-9]{8}$
