only get the src value

I have in the database a field that will always have an tag. and also lots of text..

For example:

Hey there.. whats up?
<img src="https://cdn.theatlantic.com/static/infocus/ngpc112812/s_n01_nursingm.jpg" alt="" />
.. and this is my photo!..

I need to get ONLY what between the

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;
        // do something with url here
        // return the replace value
        return @"<img src=""" + url + @""" border=""0"" />";
    },
        RegexOptions.IgnoreCase);

    result = "<img src='" + result + "'/>";

    return result;
}

But I’ve got a parsing error :

Exception Details: System.ArgumentException: parsing “([^]]+)/>” – Reference to undefined group name img.

dont know though if my code is the right path…

string matchString = Regex.Match(original_text, "<img.+?src=["'](.+?)["'].+?>", RegexOptions.IgnoreCase).Groups[1].Value;

Method 2

You can try this Regex pattern:-

string pattern= Regex.Match(path, "<img.+?src=["'](.+?)["'].+?>", RegexOptions.IgnoreCase).Groups[1].Value;
