這幾天閒 來無事，所以寫了個大文章分頁代碼，下面提供給大家。
實現思路是：後台管理員文章發布的時候自己手動添加分頁符，後台我用的也是FCKeditor，所以修改了他的source增加了自己的button。在button的事件裡寫上自己的代碼，當然就是直接insert innerHtml自己的分頁標志了，我目前用的是|,|,|,|,|,|當然可以自定義其他的。首先提供個類庫。

2 調用部分：
在ASPx中增加lable等元素。
<asp:label id="currentpage" runat="server" CSSClass="gray">當前頁</ASP:label>
<asp:label id="totalpage" runat="server" CSSClass="gray">Label</ASP:label>
<asp:hyperlink id="lnkfist" runat="server" CSSClass="gray">首頁</ASP:hyperlink>|
<asp:hyperlink id="lnkprev" runat="server" CSSClass="gray">前頁</ASP:hyperlink>|
<asp:hyperlink id="lnknext" runat="server" CSSClass="gray">下頁</ASP:hyperlink>|
<asp:hyperlink id="lnklast" runat="server" CSSClass="gray">尾頁</ASP:hyperlink>
在ASPx.cs中增加調用代碼。
private ContentPager pager;
protected void Page_Load(object sender, EventArgs e)
{
int id = Convert.ToInt32(Request.QueryString["id"]);//接收參數，例如訪問這個頁是xxx.ASPx?id=1 DataSet ds = new DataSet();
//從數據庫讀內容部分就略掉了
DataRow drow;
drow = ds.Tables[0].Rows[0];
string cont = drow["content"].ToString();//此部分可以把內容中的Html代碼轉換一下，我也省略了
//文章分頁,關鍵部分
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.content;
string query = "&id=" + Request.QueryString["id"].ToString();
pager.datapager(cont, query);
}
