 1 <div class="activity_banner">
 2         <img src="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img01.jpg" width="1900" height="540" border="0" />
 3     </div>
 4     <div class="activity_wp_cn">
 5         <img src="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img02.jpg" width="960" height="400" border="0" />
 6         <img src="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img03.jpg" width="960" height="400" border="0" />

 8      </div>

我想变成

1 <div class="activity_banner">
2         <img src="/aolai/images/e.gif" lazy="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img01.jpg" width="1900" height="540" border="0" />
3     </div>
4     <div class="activity_wp_cn">
5         <img src="/aolai/images/e.gif" lazy="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img02.jpg" width="960" height="400" border="0" />
6         <img src="/aolai/images/e.gif" lazy="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img03.jpg" width="960" height="400" border="0" />
7         <img src="/aolai/images/e.gif" lazy="http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img04.jpg" width="960" height="400" border="0" />

经测试通过:

static void Main(string[] args)
        {
            Regex r = new Regex("http:.*?\"");
            string source ="<img src=\"http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img01.jpg\" width=\"1900\" height=\"540\" border=\"0\" />";
            string dest = r.Replace(source, new MatchEvaluator(x =>"/aolai/images/e.gif\" lazy=\""+ x.ToString()));
            Console.Read();
        }
