分页的方法:
View Code public string OutputBySize( string p_strContent, string bType) { string m_strRet = "" ; int m_intPageSize = 500 ; // 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[ " ps " ] != null ) { // set Current page number try { // 处理不正常的地址栏的值 m_intCurrentPage = Convert.ToInt32(Request.QueryString[ " ps " ]); 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 if (m_intCurrentPage < m_intTotalPage) { 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); } else if (m_intCurrentPage == m_intTotalPage) { int mm_intPageSize = m_intArticlelength - m_intPageSize * (m_intCurrentPage - 1 ); m_strRet += p_strContent.Substring(m_intArticlelength - mm_intPageSize); } string m_strPageInfo = "" ; for ( int i = 1 ; i <= m_intTotalPage; i ++ ) { if (i == m_intCurrentPage) m_strPageInfo += " [ " + i + " ] " ; else m_strPageInfo += " <a href=gywm.aspx?Btype= " + bType + " &ps= " + i + " >[ " + i + " ] </a> " ; } if (m_intCurrentPage > 1 ) m_strPageInfo = " <a href=gywm.aspx?Btype= " + bType + " &ps= " + (m_intCurrentPage - 1 ) + " >上一页 </a> " + m_strPageInfo; if (m_intCurrentPage < m_intTotalPage) m_strPageInfo += " <a href=gywm.aspx?Btype= " + bType + " &ps= " + (m_intCurrentPage + 1 ) + " >下一页 </a> " ; // 输出显示各个页码 this .ShowPageNumber.Text = " <p> </p> " + m_strPageInfo; } else { m_strRet += p_strContent; } return m_strRet; }
