ASP.net连接数据库实现图片轮换

前台代码：
 <script type="text/javascript">
  <%=LoadImage() %>
imgUrl1="uploads/"+ImgSrc[0];
imgtext1=ImgAlt[0]
imgLink1=escape("adimg.aspx?Img_ID="+ImgUrl[0]);
imgUrl2="uploads/"+ImgSrc[1];
imgtext2=ImgAlt[1]
imgLink2=escape("adimg.aspx?Img_ID="+ImgUrl[1]);
imgUrl3="uploads/"+ImgSrc[2];
imgtext3=ImgAlt[2]
imgLink3=escape("adimg.aspx?Img_ID="+ImgUrl[2]);
imgUrl4="uploads/"+ImgSrc[3];
imgtext4=ImgAlt[3]
imgLink4=escape("adimg.aspx?Img_ID="+ImgUrl[3]);
imgUrl5="uploads/"+ImgSrc[4];
imgtext5=ImgAlt[4]
imgLink5=escape("adimg.aspx?Img_ID="+ImgUrl[4]);
 var focus_width=588
 var focus_height=254
 var text_height=18
 var swf_height = focus_height+text_height
 
 var pics=imgUrl1+"|"+imgUrl2+"|"+imgUrl3+"|"+imgUrl4+"|"+imgUrl5
 var links=imgLink1+"|"+imgLink2+"|"+imgLink3+"|"+imgLink4+"|"+imgLink5
 var texts=imgtext1+"|"+imgtext2+"|"+imgtext3+"|"+imgtext4+"|"+imgtext5
 
 document.write('<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="'+ focus_width +'" height="'+ swf_height +'">');
 document.write('<param name="allowScriptAccess" value="sameDomain"><param name="movie" value="images/focus.swf"><param name="quality" value="high"><param name="bgcolor" value="#F0F0F0">');
 document.write('<param name="menu" value="false"><param name=wmode value="opaque">');
 document.write('<param name="FlashVars" value="pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'">');
 document.write('</object>');
</script>
    后台代码：
 //图片新闻
    protected string LoadImage()
    {
        string sql = string.Forma
