WebClient provides an easy way to add query strings through a dictionary-style property.

WebClient wc = new WebClient();
wc.Proxy = null;
wc.QueryString.Add("q", "WebClient"); // Search for "WebClient" \
wc.QueryString.Add("hl", "fr"); // Display page in French
wc.DownloadFile("http://www.google.com/search", "results.html");
