【撒分】怎样分页？？

public static string CutString(object content, int num)
    {
        if (content.ToString().Length > num - 2)
            return content.ToString().Substring(0, num - 2) + "...";
        else
            return content.ToString();
    }
用这个方法吧，应该可以！

取出来spite一下放到数组里边，然后生成分页，这个很简单嘛

就用substring（int，int）把你的文章截成n个小段，然后显示在不同的页面上。

1 标签分页参考
2 在添加内容时，分页添加。参考IWMS

Asp.NET生成静态页面并分页

1、静态模板页面 template.html，主要是定义了一些特殊字符，用来被替换。 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Title </title>
</head>
<body>
<div style="width: 417px; height: 54px" align="center">
<br />
Title </div>
<div style="width: 417px; height: 8px">
浏览 <font color="red"> <script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=NewsId"> </script> </font>次 Time </div>
<div style="width: 417px; height: 100px">
Content </div>
<div style="width: 416px; height: 9px">
Pager </div>
<div style="width: 416px; height: 8px">
<form id="form1" action="../AddComment.aspx" style="margin:0px">
<input id="Text1" type="text" /> <Img id="Image1" src="http://www.dwww.cn/UserInfo/CheckCode.aspx"/> <br />
<textarea id="CommentContent" cols="20" rows="2"> </textarea>
<br />
<input id="NewsId" type="hidden" value="NewsId"/>
<input id="Button1" type="submit" value="button" />
<a href="http://www.dwww.cn/News/Display.aspx?NewsId=NewsId">查看更多评论 </a> </form>
</div>
</body>
</html>
2、前态页面 NewsAdd.aspx，就是一个表单，用来填写新闻的标题和内容。 <%@ Page Language="C#" AutoEventWireup="false" validateRequest="false" CodeFile="NewsAdd.aspx.cs" Inherits="NewsAdd.Admin_AdminPanel_NewsAdd" %>
<%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>添加新闻 </title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="Label2" runat="server" Text="标题"> </asp:Label>
<asp:TextBox ID="Title" runat="server" Width="325px"> </asp:TextBox> <br />
<asp:Label ID="Label1" runat="server" Text="内容"> </asp:Label>
<FCKeditorV2:FCKeditor id="Content" basePath="~/FCKeditor/" runat="server" Height="400px" Width="70%"> </FCKeditorV2:FCKeditor>
<asp:Button ID="Button1" runat="server" onClick="Button1_Click" Text="Button" />
<asp:Label ID="Message" runat="server" > </asp:Label> </div>
</form>
</body>
</html>
3、后台页面 NewsAdd.aspx.cs using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Mysqlserver;
using System.IO;
using System.Text;
namespace NewsAdd
{
public partial class Admin_AdminPanel_NewsAdd : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{ }
protected void Button1_Click(object sender, EventArgs e)
{
string strDate = DateTime.Now.ToString("yyMMdd") + "\" + DateTime.Now.ToString("yyyymmddhhmmss");
string strFileName = strDate + ".shtml";//存储到数据库中
string strTitle=Request.Form["Title"].ToString().Trim();//接收传过来的标题
string strContent=Request.Form["Content"].ToString().Trim();//接收传过来的内容
string[] content = strContent.Split(new Char[] {'|'});//对内容进行拆分，并保存到数组
int upbound = content.Length;//数组的上限
SqlServerDataBase db = new SqlServerDataBase();
bool success = db.Insert("insert into inNews(Title,Content,FilePath)values('" + strTitle + "','" + strContent + "','" + strFileName + "')", null);
//if (success)
// Message.Text = "添加成功！";
/**////////////////////////////创建当前日期的文件夹开始
string dir = Server.MapPath("../../"+"NewsFiles/"+DateTime.Now.ToString("yyMMdd"));//用来生成文件夹
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(dir);
}
/**////////////////////////////创建当前日期的文件夹结束
try
{
for (int i = 0; i < content.Length; i++)
{
//string[] newContent = new string[4];//定义和html标记数目一致的数组
StringBuilder strhtml = new StringBuilder(); //创建StreamReader对象
using (StreamReader sr = new StreamReader(Server.MapPath("../../" + "NewsFiles/") + "\template.html",Encoding.GetEncoding("gb2312")))
{
String oneline;
//读取指定的HTML文件模板
while ((oneline = sr.ReadLine()) != null)
{
strhtml.Append(oneline);
}
sr.Close();
} //为标记数组赋值
//SqlServerDataBase db = new SqlServerDataBase();
DataSet ds = db.Select("select top 1 NewsId from inNews order by NewsId desc", null);//获取id
string strTable = " <table> <tr> <td>upUrl </td> <td>Number </td> <td>downUrl </td> </tr> </table>";//上下页表格，注意此处的upUrl（上一页），Number（页码分页），downUrl（下一页）
//这三个是用来替换的。 string FilePath="";
strhtml = strhtml.Replace("Title", strTitle);
strhtml = strhtml.Replace("NewsId", ds.Tables[0].Rows[0]["NewsId"].ToString());
strhtml = strhtml.Replace("Time", DateTime.Now.ToString("yyyy/MM/dd"));
strhtml = strhtml.Replace("Content", content[i]);
string strNumber = "";//数字分页1，2，3……
for (int m = 1; m <=upbound; m++)
{
if (m == 1)//如果是第一页就显示成这个样子：20070524.shtml而不是20070524_1.shtml
strNumber = strNumber + " ["+" <a href=" + "../" + strDate + ".shtml" + ">" + m + " </a>"+"] ";
else
{
int n = m - 1;//第三页的连接应该是20070524_2.shtml，以此类推
strNumber = strNumber + " [" +" <a href=" + "../" + strDate + "_" + n + ".shtml" + ">" + m + " </a>"+"] ";
}
}
if (upbound == 0)//如果没有分页，就直接按日期时间保存
{
FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + ".shtml";
strhtml = strhtml.Replace("Pager", "");
}
else//否则按20070524.shtml、20070524_1.shtml 这种效果保存
{
if (i == 0)
FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + ".shtml";
else
FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + "_" + i + ".shtml"; if (i == 0)//第一页不显示上一页
strTable = strTable.Replace("upUrl", ""); if (i <= 1)//上一页分页
strTable = strTable.Replace("upUrl", " <a href=" + "../" + strDate + ".shtml" + ">上一页 </a>");
else
{
int p = i - 1;
strTable = strTable.Replace("upUrl", " <a href=" + "../" + strDate + "_" + p + ".shtml" + ">上一页 </a>");
} if(upbound==1)//如果只有一页，则不显示页码
//strNumber="";
strTable = strTable.Replace("Number", "");
else
strTable = strTable.Replace("Number", strNumber);//页码替换
/**/////////////////////////
if(i==upbound-1)//最后一页不显示下一页
strTable = strTable.Replace("downUrl", ""); if (i != upbound - 1)//下一页分页
{
int q = i + 1;
strTable = strTable.Replace("downUrl", " <a href=" + "../" + strDate + "_" + q + ".shtml" + ">下一页 </a>");
}
else
{
int j = upbound - 1;
strTable = strTable.Replace("downUrl", " <a href=" + "../" + strDate + "_" + j + ".shtml" + ">下一页 </a>");
} strhtml = strhtml.Replace("Pager", strTable);
}
//创建文件信息对象--------------------------------------------
FileInfo finfo = new FileInfo(FilePath);
//以打开或者写入的形式创建文件流
using (FileStream fs = finfo.OpenWrite())
{
//根据上面创建的文件流创建写数据流
StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.Default);
//把新的内容写到创建的HTML页面中
sw.WriteLine(strhtml);
sw.Flush();
sw.Close();
}
}
}
catch (Exception err)
{
//输出异常信息
Response.Write(err.ToString());
}
}
}
}
请不要直接拷贝使用，里面的路径需要更改，但程序绝对没问题，在我本地已经测试通过。另外在使用时，比如我要把新闻的内容分成4页，就应该这样写：111|222|333|444。

长文章分页：
private string OutputArticle()
{//Only output one Record of the "AriticID" is 2
string m_strRet = "";
。
／／检索数据库文章的代码。
return m_strRet;
}
对文章进行分页： public string OutputBySize(string p_strContent)
{
int m_intPageSize=1000;//文章每页大小
int m_intCurrentPage = 1;//设置第一页为初始页
int m_intTotalPage = 0;
int m_intArticlelength=p_strContent.Length;//文章长度
if (m_intPageSize < m_intArticlelength)
{//如果每页大小大于文章长度时就不用分页了
if (m_intArticlelength % m_intPageSize == 0)
{//set total pages count
m_intTotalPage = m_intArticlelength / m_intPageSize;
}
else
{//if the totalsize
m_intTotalPage = m_intArticlelength / m_intPageSize + 1;
}
if (Request.QueryString["pages"] != null)
{//set Current page number
try
{//处理不正常的地址栏的值
m_intCurrentPage = Convert.ToInt32(Request.QueryString["pages"]);
if (m_intCurrentPage > m_intTotalPage)
m_intCurrentPage = m_intTotalPage;
}
catch
{
m_intCurrentPage = m_intCurrentPage;
}
}
//set the page content 设置获取当前页的大小
m_intPageSize = m_intCurrentPage < m_intTotalPage ? m_intPageSize : (m_intArticlelength - m_intPageSize * (m_intCurrentPage - 1));
string m_strRet = p_strContent.Substring(m_intPageSize * (m_intCurrentPage - 1), m_intPageSize);
string m_strPageInfo = "<p></p>";
for (int i = 1; i <= m_intTotalPage; i++)
{
if (i == m_intCurrentPage)
m_strPageInfo += "<b>" + i + "</b>｜";
else
m_strPageInfo += "<a href=viewArticle.aspx?pages=" + i + ">" + i + "</a>｜";
}
//输出显示各个页码
this.labPageNumber.Text = m_strPageInfo;
}
return m_strRet;
}
最后在页面加载事件中调用上面的方法：
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string m_strContent = OutputArticle();
this.labContent.Text = OutputBySize(m_strContent);
}
}页面代码很简单为：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ViewArticle.aspx.cs" Inherits="ViewArticle" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="labContent" runat="server"></asp:Label>
<br />
<br />
<asp:Label ID="labPageNumber" runat="server"></asp:Label></div>
</form>
</body>
</html>
