public string pagelink(int pagesize, int recordcount, int currentpage, int prev, int next)
{
int pagecount = recordcount % pagesize == 0 ? (recordcount / pagesize) : ((int)math.ceiling((double)recordcount / pagesize));
stringbuilder sb = new stringbuilder();
if (currentpage > 1 && recordcount > 1)
{
sb.append("<a href=\"?page=");
sb.append((currentpage - 1).tostring());
sb.append("\">前一页</a> ");
}
