长文章分页，手动输入分页符

调用部分：在aspx中增加lable等元素。<asp:label id="currentpage" runat="server" CssClass="btn">当前页</asp:label>  <asp:label id="totalpage" runat="server" CssClass="btn">共多少页</asp:label>  <asp:hyperlink id="lnkfist" runat="server" CssClass="btn">首页</asp:hyperlink>|<asp:hyperlink id="lnkprev" runat="server" CssClass="btn">前页</asp:hyperlink>|<asp:hyperlink id="lnknext" runat="server" CssClass="btn">下页</asp:hyperlink>|<asp:hyperlink id="lnklast" runat="server" CssClass="btn">尾页</asp:hyperlink>

在aspx.cs中增加调用代码。

        protected void Page_Load(object sender, EventArgs e)        {

                    this.txtcontent.Text = dstSet.Tables[0].Rows[0]["nt1"].ToString();                    getPager();

        }        /// <summary>        /// 文章分页        /// </summary>        public void getPager()        {            ContentPager pager = new ContentPager();

            pager.Lnknext = this.lnknext;            pager.Lnkprev = this.lnkprev;            pager.Lnklast = this.lnklast;            pager.Lnkfist = this.lnkfist;            pager.Pagenum = this.currentpage;            pager.Pagecount = this.totalpage;            pager.DisplayContent = this.txtcontent;

            string query = "&id=" + Request.QueryString["id"].ToString();            pager.datapager(txtcontent.Text, query);        }
