WebClient.DownloadString() makes my application freeze during the "download" of the source code.

Question

Hi there guys! :D

I'm trying to have my application download the source code of a website and filter out the information that I need to pull on my application.

Everything is fine and dandy however the UI freezes until my application finishes downloading the source code of the site.

If there is anywhere I can get help, this has got to be the place. :)

Here's the code that makes me cry:

public void LoadPlayersOnline()
    {
        WebClient WebClientClass = new WebClient();

        string SiteSource = WebClientClass.DownloadString("http://forums.chronic-domination.com/");
        int AlliancePos = SiteSource.IndexOf("Alliance");
        string AlliancePlayers = SiteSource.Substring((AlliancePos + 14), 3);

        label5.Text = AlliancePlayers;
    }

You will most likely want to use DownloadStringAsync. Then implement the events on it http://msdn.microsoft.com/en-us/library/system.net.webclient%5Fevents%28VS.80%29.aspx DownloadCompleted.
