Add ?var1=data1&var2=data2 to the end of url to submit values to the page via GET:

using System.Net;
using System.IO;

string url = "https://www.example.com/scriptname.php?var1=hello";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();

    Note: this works for HTTP, I tested this code with HTTPS url and it didn't work. Going to try WebClient and see if that works with SSL – Pavdro Sep 01 '14 at 10:17
  • Use the address of this page. Stackoverflow runs on https and you will get a `200 OK` response `string url = "https://stackoverflow.com/questions/...";`. Worked! – Bitterblue Jul 09 '18 at 12:03
  • Note that WebRequest and HttpWebRequest are no longer recommended to use for new projects. Microsoft suggests using the newer HttpClient class instead: https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient – Michiel Aug 13 '21 at 11:28

Simple Get Request using HttpClient Class 

using System.Net.Http;

class Program
{
   static void Main(string[] args)
    {
        HttpClient httpClient = new HttpClient();
        var result = httpClient.GetAsync("https://www.google.com").Result;
    }

}

I prefer to use WebClient, it seems to handle SSL transparently:
