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);
        }
