FolderDialog in ConsoleApplication C #

Do this,

Just instantiate and call.

static class Program
{
    [STAThread]
    static void Main(string[] args)
    {
        FolderBrowserDialog fbd = new FolderBrowserDialog();
        if (fbd.ShowDialog() == DialogResult.OK)
        {
            foreach (var path in Directory.GetFiles(fbd.SelectedPath))
            {
                Console.WriteLine(path); // full path
                Console.WriteLine(System.IO.Path.GetFileName(path)); // file name
            }
        }


    }
}
