c# - only get the src value -

i have in database field have tag. , lots of text..

for example:

hey there.. whats up? <img src="http://cdn.theatlantic.com/static/infocus/ngpc112812/s_n01_nursingm.jpg" alt="" /> .. , photo!.. 

i need between

src

i tried :

public string linkpiccorrect(string path) {     //string input = "[img]http://imagesource.com[/img]";     string pattern = @"\<img>([^\]]+)\\/>";     string result = regex.replace(path, pattern, m =>     {         var url = m.groups[1].value;         // url here         // return replace value         return @"<img src=""" + url + @""" border=""0"" />";     },         regexoptions.ignorecase);      result = "<img src='" + result + "'/>";      return result; } 

but i've got parsing error :

exception details: system.argumentexception: parsing "\([^]]+)\/>" - reference undefined group name img.

dont know though if code right path...

this question has been asked here.

string matchstring = regex.match(original_text, "<img.+?src=[\"'](.+?)[\"'].+?>", regexoptions.ignorecase).groups[1].value;
