ASP.NET中怎么取得别人传送过来的参数？

ASP.NET中如何取得别人传送过来的参数？？
现在有如下代码向我的一个页面发出请求，我需要做的就是将它提交过来的参数全部取到，但是我不知道该怎么做，请各位大侠帮帮忙，谢谢了！

Dim   url,urlResult,return_url   as   string
Dim   HttpReq   as   object
HttpReq   =   CreateObject( "WinHttp.WinHttpRequest.5 ")
return_url   =   "http://要访问的网站 "
url   =     "storeid= "&   storeid
url   =     url   &   "&ordernumber= "&ordernumber
url   =     url   &   "&payment= "&   payment
url   =     url   &   "&note= "&   note
url   =     url   &   "&sid= "&   sid
Try
    HttpReq.Open( "POST ",return_url,false)
    HttpReq.SetResquestHeader( "Content-Type ", "application/x-www-form-urlencoded;charset=utf-8 ")
    HttpReq.Send( " "&url)
    urlResult   =   ICase(trim(HttpReq.ResponseText))
    HttpReq   =   nothing
Catch   e   as   exception
    response.write( " ")
EndTry

[解决办法]
Request[ "storeid "]

Request[ "ordernumber "]

...



[解决办法]
Request.QueryString[ "id "]
