WebClient is quite a neat way to fetch the HTML page. Here is the code snippet to download a response string.
string getHtmlPageUsingWC(string strQuery, System.Net.WebProxy proxy = null)
{
string strResponse = String.Empty;
using (WebClient wc = new WebClient())
{
wc.Encoding = Encoding.UTF8;
IWebProxy wp = WebRequest.DefaultWebProxy;
wp.Credentials = CredentialCache.DefaultCredentials;
wc.Proxy = wp;
wc.Headers.Add("Accept-Language:en");
NameValueCollection nvc = new NameValueCollection();
nvc.Add("q", strQuery);
wc.QueryString.Add(nvc);
try
{
strResponse = wc.DownloadString(m_strURL);
}
catch (Exception ex)
{
strResponse = "Request Declined: " + ex.Message;
Console.WriteLine(ex.Message);
}
}
return strResponse;
}
