Answer 1

You have Three options:

1- Using a WebClient object.

WebClient webClient = new webClient();
webClient.Credentials = new System.Net.NetworkCredential("UserName","Password", "Domain");
string pageHTML = WebClient .DownloadString("http://url");`

2- Using a WebRequest. This is the best solution because it gives you more control over your request.

WebRequest myWebRequest = WebRequest.Create("http://URL");  
WebResponse myWebResponse = myWebRequest.GetResponse();  
Stream ReceiveStream = myWebResponse.GetResponseStream();                 
Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); 
StreamReader readStream = new StreamReader( ReceiveStream, encode ); 
string strResponse=readStream.ReadToEnd();                 
StreamWriter oSw=new StreamWriter(strFilePath);     
oSw.WriteLine(strResponse); 
oSw.Close(); 
readStream.Close();        
myWebResponse.Close();

3- Using a WebBrowser (I bet you don't wanna do that)

WebBrowser wb = new WebBrowser();
wb.Navigate("http://URL");
string pageHTML = "";
wb.DocumentCompleted += (sender, e) => pageHTML = wb.DocumentText;

Excuse me if I misstyped any code because I improvised it and I don't have a syntax checker to check its correctness. But I think it should be fine.
