vb.net写的一个asp.net页面xml.aspx,包括生成rss.xml文件


	<%@ Import Namespace=System.Xml %>
	<%@ Import Namespace=System.IO %>
	<%@ Import Namespace=System.Data %>
	<%@ Import Namespace=System.Data.SqlClient %>
	<script language=VB runat=server>
	 public sub Page_Load(Src as Object, e as EventArgs)
	 Dim xmlDoc as String = Server.MapPath(rss.xml)
	 Dim writer as XmlTextWriter
	
	 Dim sqlString As String
	 Dim myConnection As SQLConnection
	 Dim myCommand As SQLCommand
	 Dim myDataReader As SqlDataReader
	 Dim myConn As String = System.Configuration.ConfigurationSettings.AppSettings(Conn)
	 Dim i_id As String
	 Dim i_title As String
	 Dim i_content As String
	 Dim i_day As String
	 sqlString = select top 10 id,i_title,i_content,i_day from information order by id desc
	 myConnection = New SQLConnection( myConn )
	 myCommand = New SQLCommand( sqlString, myConnection )
	 myConnection.Open()
	 myDataReader = myCommand.ExecuteReader()
	 try
	 writer = new XmlTextWriter(xmlDoc,Encoding.UTF8)
	 writer.Formatting = Formatting.Indented
	 writer.WriteStartDocument(true)
	 writer.WriteComment(注释)
	 writer.WriteStartElement(rss)
	 writer.WriteAttributeString(version,0.92)
	 writer.WriteStartElement(channel)
	 writer.WriteStartElement(title)
	 writer.WriteString(频道名称)
	 writer.WriteEndElement()
	 writer.WriteStartElement(link)
	 writer.WriteString(http://你的网址/)
	 writer.WriteEndElement()
	 writer.WriteStartElement(description)
	 writer.WriteString(最新的十条信息!)
	 writer.WriteEndElement()
	 writer.WriteStartElement(language)
	 writer.WriteString(zh-cn)
	 writer.WriteEndElement()
	 ''''循环开始
	 While myDataReader.Read()
	 i_id = myDataReader.GetInt32(0).ToString()
	 i_title = myDataReader.GetString(1).Trim()
	 i_content = myDataReader.GetString(2).Trim()
	 i_day = myDataReader.GetDateTime(3).ToString()

	 writer.WriteStartElement(item)
	 writer.WriteStartElement(title)
	 writer.WriteString(i_title)
	 writer.WriteEndElement()
	 writer.WriteStartElement(description)
	 writer.WriteCData(left(i_content,100))
	 writer.WriteEndElement()
	 writer.WriteStartElement(pubDate)
	 writer.WriteString(i_day)
	 writer.WriteEndElement()
	 writer.WriteStartElement(link)
	 writer.WriteString(http://你的网址/jnszf.aspx?id=&i_id)
	 writer.WriteEndElement()
	 writer.WriteEndElement()
	 End While
	 ''''循环结束
	 writer.WriteEndElement()
	 writer.WriteEndElement()
	 writer.Flush()
	 writer.Close()
	 Dim doc as XmlDocument = new XmlDocument()
	 doc.Load(xmlDoc)
	 Response.ContentType = text/xml
	 doc.Save(Response.Output)
	 catch exp as Exception
	 Response.Write(exp.ToString())
	 finally
	 if (NOT writer is Nothing) then
	 writer.Close()
	 end if
	 end try
	
	 myDataReader.Close()
	 myConnection.Close()
	 end sub
	</script>

	相同的效果如rss.aspx页面
	<%@ Import Namespace=System.Data %>
	<%@ Import Namespace=System.Data.SqlClient %>
	<script language=vb runat=server>
	Sub Page_Load(Sender as object,e as eventargs)
	 Dim myConnection As SqlConnection
	 Dim myAdapter As SqlDataAdapter
	 Dim sqlString As String
	 Dim myDataSet As DataSet
	 Dim myConn As String = System.Configuration.ConfigurationSettings.AppSettings(Conn)
	 myConnection = New SQLConnection( myConn )
	 sqlString = select top 10 * from information order by id desc
	 myAdapter = New SQLDataAdapter( sqlString, myConnection )
	 myDataSet = New DataSet
	 myAdapter.Fill( myDataSet, information )
	 Response.ContentType = Text/XML
	 myRepeater.DataSource = myDataSet
	 myRepeater.DataBind()
	End Sub
	</script>
	<?xml version=1.0 encoding=gb2312 ?>
	<rss version=0.92 >
	 <channel>
	 <title>频道名称</title>
	 <link>http://你的网址/</link>
	 <description>最新的十条记录</description>
	 <language>zh-cn</language>
	 <asp:Repeater id=myRepeater runat=server>
	 <ItemTemplate>
	 <item>
	 <title><%#DataBinder.Eval(Container.DataItem,i_title)%></title>
	 <description><![CDATA[<%#DataBinder.Eval(Container.DataItem,i_title)%>]]></description>
	 <pubDate><%#DataBinder.Eval(Container.DataItem,i_day)%></pubDate>
	 <link>http://你的网址/jnszf.aspx?id=<%#DataBinder.Eval(Container.DataItem, id)%></link>
	 </item>
	 </ItemTemplate>
	 </asp:Repeater>
	 </channel>
	</rss>
