What's wrong with just reading original MSDN documentation?

In my case I have parent directory and inside that I have many sub-directories. On my button click parent directory list down all the files and directories but when I click the sub-directories it's not listing anything

I had made a small project that lists all files. I needed to do that to list a collection of 1 tb of mp3 that i had on my portable HD. When I read this enquery, I searched for that project but I could not find it :( Ill try again...

here you are. try it and let me know if you need anything else:

C#

private void Form1_Load(object sender, EventArgs e)
        {
            var sb = new StringBuilder();
            DirSearch(@"C:\Users\vitor\Documents\Visual Studio 2012\Projects\WindowsFormsApplication2", sb);

            //save on a txt file
            File.WriteAllText(@"C:\Users\vitor\Desktop\output.txt", sb.ToString());
        }

        static string ultimaLinha = "";
        static void DirSearch(string sDir, StringBuilder sb)
        {
            try
            {
                foreach (string d in Directory.GetDirectories(sDir))
                {
                    string u = d.Substring(0, d.LastIndexOf("\\"));
                    if (u != ultimaLinha)
                    {
                        //files
                        foreach (string file in Directory.GetFiles(d))
                            sb.AppendLine(file);
                        //directory only
                        //sb.AppendLine(d);
                    }
                    ultimaLinha = u;
                    DirSearch(d, sb);
                }
            }
            catch (System.Exception excpt)
            {
                Console.WriteLine(excpt.Message);
            }
        }
