It's the very first time for me to be here.

But I think(be sure) I can get right answer here.
 

 How to imitiate PHP function curl_XXX with ASP.NET.

I'm converting some project of php into ASP.NET.

And I've found some problem as following.

        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, urlstring + '&FileName=' + salesId);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $data = curl_exec($ch);
        curl_close($ch);

So what I want to know is how to operate web page in background with ASP.NET.

Please help. This is urgent.

Hope your help. 

Thank you all.
