代码片断:利用正则表达式替换文本中匹配的字符串
- private string GetNewString(string str_old)
- {
- string str_new = string.Empty;
- string pattern = @"http://www.mysite/blog/photo/\w+/\w+/[a-zA-z0-9_\-]+";
- MatchCollection matchs = Regex.Matches(str_old,pattern);
- foreach (Match match in matchs)
- {
- str_new = match.Value.Replace("www.mysite/blog/photo","hr.mysite.com/blog");
- str_new = str_new.Replace("o_","w_");
- str_old = str_old.Replace(match.Value,str_new);
- }
- return str_old;
- }
