ASP.NET实现HTTP方式获取功能

<%@ Assembly Name="System.Net" %>
<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<script language="VB" runat="server">
dim STRtemp as string
Sub Page_Load(Src As Object, E As EventArgs)
Dim HttpWResp as HTTPWebresponse
Dim sr As StreamReader
'dim STRtemp as string
dim build as new stringbuilder

HttpWReq = WebRequestFactory.Create("http://www.funinspace.com")
HttpWReq.KeepAlive = false
HttpWResp = HttpWReq.GetResponse()
sr = new StreamReader(HttpWResp.GetResponseStream(), Encoding.ASCII)

Try
line=sr.ReadLine()
lineENC = server.HTMLencode(line) & vbcrlf & "<br>"
build.append (lineENC)

do while not IsNothing(line)
line = sr.ReadLine()
lineENC = server.HTMLencode(line) & vbcrlf & "<br>"
build.append (lineENC)
loop
Catch ex As Exception
problem.text =ex.Message
End Try

labelscrape.text=build.ToString()
End Sub
</script>
<html><head>
<title>Scraping A Website</title>
</head>
<body bgcolor="#FFFFFF">
<h3><font face="Verdana">Scraped Data</font></h3>
<asp:label id=problem runat="server"/>
