替换 [em15]



            string source = "xxxx[em15]xxxxx[em15]xxxxxx";

            string replacestr = @"<img src=""/img/mood/15.gif"" border=""0"" />";

            Regex reg = new Regex(@"\[em15\]");

            source = reg.Replace(source, replacestr);

替换成<img



            string source = @"xxxx<img src=""/img/mood/15.gif"" border=""0"" />xxxxx<img src=""/img/mood/15.gif"" border=""0"" />xxxxxx";

            string replacestr = @"[em15]";

            Regex reg = new Regex(@"<img[^>].*?15.gif.*?/>");

            source = reg.Replace(source, replacestr);

根据实际情况调试一下吧
