if ((recordCount % pageSize) > 0)

else

if (pageIndex == 1)//第一页
{

}
else if (pageIndex > pageCount)//超出总页数

还有调用示例：html代码
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="" >
