Answer 1

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;
    }
}
