This page presents the WebLinkListExample in CeeSharp, using the DotNet framework and SDK, on a WinXP-professional system.

Installation

Download the following:

Version 1.1 Redistributable framework (http://www.microsoft.com/downloads/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en)

Install the two downloads:

Run dotnetfx.exe (the redistributable)
Run setup.exe (the SDK)

Append the framework and SDK to the "Path" environment variable (I use the system properties dialog of "My Computer")

        {

        const int bufsize = 1024;


        static void Main (string[] args)

        {

        if (args.Length < 0) {

        Console.WriteLine ("Error: Missing URL");

        return;

        }


        StreamReader reader = null;


        try {

        WebRequest request = WebRequest.Create (args[0]);

        WebResponse response = request.GetResponse();

        reader = new StreamReader (response.GetResponseStream());

        string content = reader.ReadToEnd();


        Regex regex = new Regex ("href\\s*=\\s*\"([^\"]*)\"",

        RegexOptions.IgnoreCase);


        MatchCollection matches = regex.Matches (content);

        foreach (Match match in matches) Console.WriteLine (match.Groups[1]);

        }


        catch (IOException e) {

        Console.WriteLine (e.Message);

        }

        finally {

        if (reader != null) reader.Close ();

        }
