大型网站的新闻系统 一般都是以静态html文件的形式出现，这样做的好处就是对搜索引擎友好，能保证搜索引擎有效地收录网站内容．

下面我提出两种解决办法，首先看看微软的解决办法．

方法一：微软的解决办法：

This step-by-step article describes how to retrieve the HTML results of a page as a stream and then download the stream to a file. When you use the FileStream object and set the Response.Filter property to the FileStream object, all HTTP output that Response.Write sends also downloads as stream to a file.

Create a Web Form

To create a Web Form:

1.

In Visual C# .NET, create a new ASP.NET Web Application project named ASPNETFilter.

2.

Right-click the designer pane of WebForm1.aspx.

3.

Click View HTML Source to edit the HTML code.

4.

Replace the existing code with the following code :

〈%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="ASPNETFilter.WebForm1" %>

〈HTML>

〈HEAD>

〈／HEAD>

〈body>

〈form method="post" runat="server">

〈asp:TextBox Text="Textbox 1" Runat="server" />

〈asp:ListBox Runat="server" Size="3">

〈asp:ListItem Value="0">Zero

〈asp:ListItem Value="1" Selected="True">One

〈asp:ListItem Value="2">Two

〈/asp:ListBox>〈br>

〈asp:CheckBox Runat="server" Checked="True" Text="Checkbox 1" />

〈/form>

〈/body>

〈/HTML>

Create the ResponseFilter Class

To create the ResponseFilter class:

1.

Add a new class named ResponseFilter.cs.

2.

Replace the existing code with the following code:

using System;

using System.IO;

namespace ASPNETFilter

{

public class ResponseFilter : Stream

{

private Stream m_sink;

private long m_position;

private FileStream fs;

public ResponseFilter(Stream sink)

{

m_sink = sink;

fs = new FileStream(@"C:\FilterOutput\response.htm", FileMode.OpenOrCreate, FileAccess.Write);

}

// The following members of Stream must be overriden.

public override bool CanRead

{get { return true; }}

public override bool CanSeek

{get { return false; }}

public override bool CanWrite

{get { return false; }}

public override long Length

{get { return 0; }}

public override long Position

{

get { return m_position; }

set { m_position = value; }

}

public override long Seek(long offset, System.IO.SeekOrigin direction)

{

return 0;

}

public override void SetLength(long length)

{

m_sink.SetLength(length);

}

public override void Close()

{

m_sink.Close();

fs.Close();

}

public override void Flush()

{

m_sink.Flush();

}

public override int Read(byte[] buffer, int offset, int count)

{

return m_sink.Read(buffer, offset, count);

}

// Override the Write method to filter Response to a file.

public override void Write(byte[] buffer, int offset, int count)

{

//Write out the response to the browser.

m_sink.Write(buffer, 0, count);

//Write out the response to the file.

fs.Write(buffer, 0, count);

}

}

}

Note Before you run the Web application:

1.

Create a folder named C:\FilterOutput.

2.

Grant read and write access on the folder for the ASPNET user.

Use the Response Filter Class

1.

In Solution Explorer, select WebForm1.aspx.

2.

Right-click and then select View Code.
