Answer 2

The WebClient class will do what you want:

string address = "http://stackoverflow.com/";   

using (WebClient wc = new WebClient())
{
    string content = wc.DownloadString(address);
}

As mentioned in the comments, you might prefer to use the async version of DownloadString to avoid blocking:

string address = "http://stackoverflow.com/";

using (WebClient wc = new WebClient())
{
    wc.DownloadStringCompleted +=
        new DownloadStringCompletedEventHandler(DownloadCompleted);
    wc.DownloadStringAsync(new Uri(address));
}

// ...

void DownloadCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    if ((e.Error == null) && !e.Cancelled)
    {
        string content = e.Result;
    }
}

If you are planning to do a lot of web requests to access rest services, be careful with the HttpWebRequest object. It takes a while to be reclaimed and if you have enough traffic (just a few calls a minute), you can start to get strange behavior.

if you are loading other pages dynamically, I'd recommend doing it in javascript.
