Search files in C# recursively

I found this piece of code to search a for a file that containing a pattern (extension, part of the name) 

void DirSearch(string dir, string pattern)

{

    try

    {

        foreach (string d in Directory.GetDirectories(dir))

        {

            foreach (string f in Directory.GetFiles(d, pattern))

            {

                Console.WriteLine("File found: {0}", f);

         }

            DirSearch(d);

        }

    }

    catch (Exception ex)

    {

        Console.WriteLine("Something unexpected happened: {0}", ex);

    }

}

 

I've always thought that the recursive algorithms are an easy small and elegant way to solve a problem, I first learned that in college while I was studying some of the "classical" samples of recursive problems, like fractals, the problem of the 8 queens, tree search, and other graph related problems, the-horse-in-the-chess-board (I am not sure of the name), and others

I'll try to remember some of those problems and try to solve them again using C#
