自己写分页算法
我这里封装在用户控件里。你也可以封装在类文件中。自己定义:
[csharp]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
namespace HHWeb.UserControl
{
public partial class Paging : System.Web.UI.UserControl
{
public StringBuilder PagingControlInfo = new StringBuilder();
protected void Page_Load(object sender, EventArgs e)
{
GetPaging();
}
void GetPaging()
{
//判断如果当前页为负数或者零时,NowPage=1
if (NowPage <= 0)
NowPage = 1;
//判断如果当前页大于总页数时,NowPage=PageCount
int PageCount = GetPageCount();
if (NowPage > PageCount)
NowPage = PageCount;
//首页和上一页()
if (NowPage != 1)
{
PagingControlInfo.Append("<a href=\""+PageName+"?NowPage=1\">首页</a>");
PagingControlInfo.Append("<a href=\""+PageName+"?NowPage=" + (NowPage - 1) + "\">上一页</a>");
}
//如果分页总页数小于页码数(PageNumber)时,不显示省略号(...)
if (PageCount <= PageNumber)
{
for (int i = 1; i <= PageCount; i++)
GetPageNumberStr(i);
}
else
{
if (PageNumber % 2 != 0)
{
LeftPageNumberOne = (PageNumber / 2) + 1;
LeftPageNumberTwo = (PageNumber / 2);
RightPageNumber = (PageNumber / 2);
}
else
{
LeftPageNumberOne = (PageNumber / 2) + 1;
LeftPageNumberTwo = (PageNumber / 2);
RightPageNumber = (PageNumber / 2) - 1;
}
//总页数大于页码数(PageNumber)时(简单处理--算法)
if (NowPage > LeftPageNumberOne && NowPage < PageCount - RightPageNumber)
{
PagingControlInfo.Append("<span>...</span>");
for (int i = NowPage - LeftPageNumberTwo; i <= NowPage + RightPageNumber; i++)
GetPageNumberStr(i);
PagingControlInfo.Append("<span>...</span>");
}
else if (NowPage >= PageCount - RightPageNumber)
{
PagingControlInfo.Append("<span>...</span>");
for (int i = (PageCount - PageNumber) + 1; i <= PageCount; i++)
GetPageNumberStr(i);
}
else
{
for (int i = 1; i <= PageNumber; i++)
