关于用HttpWebRequest登录网页

[wolf516]

1)我已经的到Cookie的文本串:
cdb_sid=5bDuqi; cdb_cookietime=315360000; cdb_visitedfid=5D4D3; cdb_auth=B1MGBgxUXApeAVUADQMEUVdXD1UFVQZWAAUGBVQBWAE8b1E; cdb_fid5=1136348976

如何通过HttpWebRequest打开需要登录的网页,得到里面的代码?
Dim cc As New CookieContainer
Dim c As New Cookie
tCook = AxWebBrowser1.Document.cookie'取浏览器的cookie
V = Split(tCook, ";")
For i = 0 To UBound(V)
Temp = Trim(V(i) & "")
If Trim(Temp & "") <> "" Then
c.Name = Temp.Substring(0, InStr(Temp, "=") - 1)
c.Value = Temp.Substring(InStr(Temp, "="))
cc.Add(uri, c)
End If
Next
httpReq.CookieContainer = cc

再用HttpResponse打开网页时,得到的还是没有登录的状态.
小弟初接触vb.net及它的http编程.希望哪位高手给指教一下.
