string yourStr = " <P> 前去轻轻巧巧巧 <IMG src= "http://www.gdqd.com/upimage/20075314591127.jpg " border=0> </P>
<P> 啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊 </P> ";
string resultStr = " ";
Match m = Regex.Match(yourStr, @ " <img\s+src= " "[^ " "]*?/(? <pho> [^/ " "]*?) " "[^> ]*?> ", RegexOptions.IgnoreCase);
if(m.Success)
{
resultStr = m.Groups[ "pho "].Value;
