Asp.NET生成静态页面并分页(文章内容分页)-NET编程

主要的原理就是替换模板里的特殊字符。

1、静态模板页面 template.html,主要是定义了一些特殊字符,用来被替换。

 
  1. <!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
  2. <html>
  3. <head>
  4. <metahttp-equiv="Content-Type"content="text/html;charset=gb2312">
  5. <title>Title</title>
  6. </head>
  7. <body>
  8. <divstyle="width:417px;height:54px"align="center">
  9. <br/>
  10. Title</div>
  11. <divstyle="width:417px;height:8px">
  12. 浏览<fontcolor="red"><scriptsrc="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=NewsId"></script></font>次Time</div>
  13. <divstyle="width:417px;height:100px">
  14. Content</div>
  15. <divstyle="width:416px;height:9px">
  16. Pager</div>
  17. <divstyle="width:416px;height:8px">
  18. <formid="form1"action="../AddComment.aspx"style="margin:0px">
  19. <inputid="Text1"type="text"/><Imgid="Image1"src="http://www.dwww.cn/UserInfo/CheckCode.aspx"/><br/>
  20. <textareaid="CommentContent"cols="20"rows="2"></textarea>
  21. <br/>
  22. <inputid="NewsId"type="hidden"value="NewsId"/>
  23. <inputid="Button1"type="submit"value="button"/>
  24. <ahref="http://www.dwww.cn/News/Display.aspx?NewsId=NewsId">查看更多评论</a></form>
  25. </div>
  26. </body>
  27. </html>

2、前态页面 NewsAdd.aspx,就是一个表单,用来填写新闻的标题和内容。

 
  1. <%@PageLanguage="C#"AutoEventWireup="false"validateRequest="false"CodeFile="NewsAdd.aspx.cs"Inherits="NewsAdd.Admin_AdminPanel_NewsAdd"%>
  2. <%@RegisterTagPrefix="FCKeditorV2"Namespace="FredCK.FCKeditorV2"Assembly="FredCK.FCKeditorV2"%>
  3. <!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  4. <htmlxmlns="http://www.w3.org/1999/xhtml">
  5. <headrunat="server">
  6. <title>添加新闻</title>
  7. </head>
  8. <body>
  9. <formid="form1"runat="server">
  10. <div>
  11. <asp:LabelID="Label2"runat="server"Text="标题"></asp:Label>
  12. <asp:TextBoxID="Title"runat="server"Width="325px"></asp:TextBox><br/>
  13. <asp:LabelID="Label1"runat="server"Text="内容"></asp:Label>
  14. <FCKeditorV2:FCKeditorid="Content"basePath="~/FCKeditor/"runat="server"Height="400px"Width="70%"></FCKeditorV2:FCKeditor>
  15. <asp:ButtonID="Button1"runat="server"onClick="Button1_Click"Text="Button"/>
  16. <asp:LabelID="Message"runat="server"></asp:Label></div>
  17. </form>
  18. </body>
  19. </html>

3、后台页面 NewsAdd.aspx.cs
