1. Simple generation of htm page code without paging

The code is as follows: Copy code

Using system;
Using system. data;
Using system. configuration;
Using system. collections;
Using system. web;
Using system. web. security;
Using system. web. ui;
Using system. web. ui. webcontrols;
Using system. web. ui. webcontrols. webparts;
Using system.web.ui.html controls;
Using mysqlserver; // database operation class
Using system. io;
Using system. text;
Namespace newsadd
{
Public partial class Admin_AdminPanel_NewsAdd: System. Web. UI. Page
{
Protected void Page_Load (object sender, EventArgs e)
 {
 }
Protected void button#click (object sender, EventArgs e)
 {
String strTitle = Request. Form ["Title"]. ToString ();
String strContent = Request. Form ["Content"]. ToString ();
SqlServerDataBase db = new SqlServerDataBase ();
Bool success = db. Insert ("insert into inNews (Title, Content) values ('" + strTitle + "', '" + strContent + "')", null );
// If (success)
// Message. Text = "added successfully! ";
/** // Start the creation of the folder on the current date
String dir = Server. MapPath (".../" + "NewsFiles/" + DateTime. Now. ToString ("yyMMdd "));
If (! Directory. Exists (dir ))
     {
Directory. CreateDirectory (dir );
     }
/** // End of the folder on the current creation date

String [] newContent = new string [5]; // defines an array with the same number of html tags
StringBuilder strhtml = new StringBuilder ();
Try
     {
// Create a StreamReader object
Using (StreamReader sr = new StreamReader (Server. MapPath (".../../" + "NewsFiles/") + "/template.html "))
  {
String oneline;
// Read the specified HTML file Template
While (oneline = sr. ReadLine ())! = Null)
      {
Strhtml. Append (oneline );
      }
Sr. Close ();
  }
     }
Catch (Exception err)
     {
// Output exception information
Response. Write (err. ToString ());
     }
// Assign values to the marked array
NewContent [0] = strTitle; // title
NewContent [1] = "BackColor = '# cccfff'"; // background color
NewContent [2] = "# ff0000"; // font color
NewContent [3] = "100px"; // font size
NewContent [4] = strContent; // Main content
// Generate an html file based on the new content above
Try
     {
// Specify the HTML file to be generated
String fname = Server. mapPath (".. /.. /"+" NewsFiles/"+ DateTime. now. toString ("yyMMdd") + "/" + DateTime. now. toString ("yyyymmddhhmmss") + ". html ";
// Replace the new content in the html template file
For (int I = 0; I <5; I ++)
  {
Strhtml. Replace ("$ htmlkey [" + I + "]", newContent [I]);
  }
// Create a file information object
FileInfo finfo = new FileInfo (fname );
// Create a file stream in the form of opening or writing
Using (FileStream fs = finfo. OpenWrite ())
  {
// Create a write data stream based on the file stream created above
StreamWriter sw = new StreamWriter (fs, System. Text. Encoding. GetEncoding ("GB2312 "));
// Write the new content to the created HTML page
Sw. WriteLine (strhtml );
Sw. Flush ();
Sw. Close ();
  }
     }
Catch (Exception err)
     {
Response. Write (err. ToString ());
     }
 }
}
}

2. Template.html

The code is as follows: Copy code

<Html>
<Head>
<Title> $ htmlkey [0] </title>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312">
</Head>
<Body>
<Table $ htmlkey [1] height = "100%" border = "0" width = "100%" cellpadding = "10" cellspacing = "0" bgcolor = "# eeeeee" style = "border: 1px solid #000000 "mce_style =" border: 1px solid #000000 ">
<Tr>
<Td width = "100%" valign = "middle" align = "left">
<Span style = "color: $ htmlkey [2]; font-size: $ htmlkey [3]" mce_style = "color: $ htmlkey [2]; font-size: $ htmlkey [3] "> $ htmlkey [4] </span>
</Td>
</Tr>
</Table>
</Body>
</Html>

The code above does not have the paging function. If you want to pagination, we need to perform some processing.


1. Static template page template.html, which defines some special characters for replacement.
 

The code is as follows: Copy code
<! Doctype html public "-// W3C // dtd html 4.01 Transitional // EN" "http://www.w3.org/TR/html4/loose.dtd">
<Html>
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312">
<Title> asp.net: generate static page _ www.111cn.net </title>
</Head>
<Body>
<Div style = "width: Pixel px; height: 54px" align = "center">
<Br/>
Title </div>
<Div style = "width: Pixel px; height: 8px">
Browse <font color = "red"> <script src = "http: // localhost/. Net/NewsFiles/ClickCount. aspx? NewsId = NewsId "> </script> </font> Time </div>
<Div style = "width: Pixel px; height: 100px">
Content </div>
<Div style = "width: 416px; height: 9px">
Pager </div>
<Div style = "width: 416px; height: 8px">
<Form id = "form1" action = ".../AddComment. aspx" style = "margin: 0px">
<Input id = "Text1" type = "text"/> <br/>
<Textarea id = "CommentContent" cols = "20" rows = "2"> </textarea>
<Br/>
<Input id = "NewsId" type = "hidden" value = "NewsId"/>
<Input id = "Button1" type = "submit" value = "button"/>
<A href = "/News/Display. aspx? NewsId = NewsId "> View More comments </a> </form>
</Div>
</Body>
</Html>

2. NewsAdd. aspx
A form that is used to enter the news title and content.

The code is as follows: Copy code
<% @ Page Language = "C #" AutoEventWireup = "false" validateRequest = "false" CodeFile = "NewsAdd. aspx. cs" Inherits = "NewsAdd. Admin_AdminPanel_NewsAdd" %>
<% @ Register TagPrefix = "FCKeditorV2" Namespace = "FredCK. FCKeditorV2" Assembly = "FredCK. FCKeditorV2" %>
<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<Html xmlns = "http://www.w3.org/1999/xhtml">
<Head runat = "server">
<Title> add news_www.111cn.net </title>
</Head>
<Body>
<Form id = "form1" runat = "server">
<Div>
<Asp: Label ID = "Label2" runat = "server" Text = "title"> </asp: Label>
<Asp: TextBox ID = "Title" runat = "server" Width = "325px"> </asp: TextBox> <br/>
<Asp: Label ID = "Label1" runat = "server" Text = "content"> </asp: Label>
<FCKeditorV2: FCKeditor id = "Content" basePath = "~ /FCKeditor/"runat =" server "Height =" 400px "Width =" 70% "> </FCKeditorV2: FCKeditor>
<Asp: Button ID = "Button1" runat = "server" onClick = "button#click" Text = "Button"/>
<Asp: Label ID = "Message" runat = "server"> </asp: Label> </div>
</Form>
</Body>
</Html>

Ps: If you want to add a next hop box, you can use for operations.

The code is as follows: Copy code

For (int j = 1; j <= (pageTotal + 1); j ++)
{
If (j = 1)
    {
Sb. Append ("<option value = '" + absolutePaths + "\" + name + ". html"> "+ j +" </option> ");
    }
Else
    {
Sb. append ("<option value = '" + absolutePaths + "\" + name + "-" + (j-1) + ". html '> "+ j +" </option> ");
    }
}
