redirect to PHP page from C# code

[C# Programming]

Hi for all
im now tring to redirect my project to PHP page from C# APP
and i used these lines (code):
// prepare the web page we will be asking for
HttpWebRequest request = (HttpWebRequest)
WebRequest.Create("http://localhost/d.php");

// execute the request
HttpWebResponse response = (HttpWebResponse)
request.GetResponse();


that executed my program without showing me a PHP page in my browser

and i used these lines also as my code

string targetURL = @"http://localhost/MyPage.php";
System.Diagnostics.Process.Start(targetURL);


and that run true but i prefer the first method to do that
So any help

Thanks in advance
