How do I connect to router "panel" using C#

Question

I'm trying to connect to my router "panel" (192.168.1.1) using a simple C# HTTP Web Request:

var userName = "admin";
var passWord = "admin";
var encoding = new ASCIIEncoding();
var postData = "" + userName;
postData += (":" + passWord); //I saw (using Wireshark) that the HTTP packet is sending the username & password in this form: "username:password"
byte[] data = encoding.GetBytes(postData);

var myRequest = (HttpWebRequest)WebRequest.Create("http://192.168.1.1");
myRequest.Method = "POST"; **//Or should I use GET?**
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
var newStream = myRequest.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();
try
{
  var response = myRequest.GetResponse();
  var responseStream = response.GetResponseStream();
  var responseReader = new StreamReader(responseStream);
  var result = responseReader.ReadToEnd();
}
catch (WebException we)
{
  Console.WriteLine(we.Message);
}

When I'm running this code I get an saying '401 Not Authorized Exception', although the UN and Password are correct.

Can anyone suggest me, what's wrong here?

What type (i.e. make and model) of router are you connecting to? — slickboy, Jun 17 '13 at 09:45

Have you tried using this as the address and dropping the post data part of your code :

http://username:password@192.168.1.1

Else, you could use basic authentication, as explained in this article

I tried this: `var myRequest = (HttpWebRequest)WebRequest.Create("http://admin:admin@192.168.2.1");` `myRequest.Method = "POST";` `myRequest.ContentType = "application/x-www-form-urlencoded";` `var response = myRequest.GetResponse();` `var responseStream = response.GetResponseStream();` `var responseReader = new StreamReader(responseStream);` `var result = responseReader.ReadToEnd();` but I still get an 401 Unauthorized Exception – albeck Jun 17 '13 at 09:58
i'm not sure you've got to POST this as you're doing, I think you should use basic authentication : http://grahamrhay.wordpress.com/2011/08/22/making-a-post-request-in-c-with-basic-authentication/ – Laurent S. Jun 17 '13 at 10:04
