------解决方案--------------------
C# code
     MatchCollection mc = Regex.Matches(htmlEditor2.Text, @"<IMG\s?src=(?<url>.*?)>");
            string s = "";
            foreach (Match m in mc)
            {
                s+= m.Groups["url"].Value;
            }

------解决方案--------------------
(?is)<IMG\b[^>]*?src=(["']?)(?<url>[^'"]*?)\1[^>]*?>
C# code

            MatchCollection mc = Regex.Matches(htmlEditor2.Text, @"(?is)<IMG\b[^>]*?src=([""']?)(?<url>[^'""]*?)\1[^>]*?>");
            List<string> s = new List<string>();
            foreach (Match m in mc)
            {
                s.Add(m.Groups["url"].Value);
            }
