我想得到http://images.gg-art.com/auction/images1/13/13325.jpg
怎么写呢，新手，不好意思了

string str = @"1111http://images.gg-art.com/auction/images1/13/13325.jpg..aaaa";
string s = @"http://[^\s]*.jpg";
Regex r = new Regex(s, RegexOptions.IgnoreCase);
Match m = r.Match(str);
Console.WriteLine(m.Groups[0]);

string str = @"<img src=http://images.gg-art.com/auction/images1/13/13325.jpg>";
string s = "<img[^>]+?src=(|\"|\')([^\'\"]+)>";
Regex r = new Regex(s, RegexOptions.IgnoreCase);
Match m = r.Match(str);
Console.WriteLine(m.Groups[2]);

<img[\s]*src[\s]*=(?<src>http://[\w\W]*.jpg)>

 string str = @" <img src=http://images.gg-art.com/auction/images1/13/13325.jpg >";
            Regex r = new Regex(@"<img[\s]*src[\s]*=(?<src>http://[\w\W]*.jpg)[\s]*>", RegexOptions.IgnoreCase);
            if (r.IsMatch(str))
            {
                Response.Write(r.Match(str).Groups["src"].Value.ToString());
            }
