简易文章分页

1.页面端添加相关代码

2.绑定到相应控件

 Label4.Text = OutputBySize(Server.HtmlDecode(newss.Contents), fid);

3.相关方法

        public string OutputBySize(string p_strContent, int pageid)
        {
            string m_strRet = p_strContent;
            int m_intPageSize = 10;//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

                }
                //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));
                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>｜";

                }
                //输出显示各个页码
                this.labPageNumber.Text = m_strPageInfo;
            }
            return m_strRet;
        }
