移除字符

Question

我想移除字符,单独提取＂200803302320350＂怎么做才可以？
string w_z ="http://www.ccnf.com/ccnf_assist/200803/termainal_200803302320350_0.shtml".ToString();
Response.Write(w_z.Trim('_'));

Answer 1

        string w_z = "http://www.ccnf.com/ccnf_assist/200803/termainal_200803302320350_0.shtml".ToString();
        Match M= Regex.Match(w_z, "(\\d){15}");
        Response.Write(M.Groups[0].Value);
别忘了加using System.Text.RegularExpressions;记得给我撤分

Answer 2

        string w_z = "http://www.ccnf.com/ccnf_assist/200803/termainal_200803302320350_0.shtml";
        Match M= Regex.Match(w_z, "_(\\d+)_");
        Response.Write(M.Groups[1].Value);这样也可以，总之正则很强大，兄弟努力！
