title: C# - Playing random sound files from folder
body: <p>I'm attempting to create an Oracle (read: Magic 8 Ball).
  The idea behind it is that on each button press, a sound file with wise words is played (picked at random).
  I have it working using switches, however I'm searching for a way to make it more.. logical.</p>
  
  <p>This is how it currently looks, with the switches going on and on:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  using System.Windows.Forms;
  
  namespace _8ball
  {
      public partial class Form1 : Form
      {
          public Form1()
          {
              InitializeComponent();
          }
  
          private void button1_Click(object sender, EventArgs e)
          {
              Random rnd = new Random(Guid.NewGuid().GetHashCode());
              int choices = rnd.Next(0, 62);
              switch(choices)
              { 
                  case 0:
                      System.Media.SoundPlayer player = new System.Media.SoundPlayer(@"c:\Lyde\0.wav");
                      player.Play();
                      break;
                  case 1:
                      System.Media.SoundPlayer player1 = new System.Media.SoundPlayer(@"c:\Lyde\1.wav");
                      player1.Play();
                      break;
                  case 2:
                      System.Media.SoundPlayer player2 = new System.Media.SoundPlayer(@"c:\Lyde\2.wav");
                      player2.Play();
                      break;
                  case 3:
                      System.Media.SoundPlayer player3 = new System.Media.SoundPlayer(@"c:\Lyde\3.wav");
                      player3.Play();
                      break;
  </code></pre>
  
  <p>Surely there is a way to program it as such so that it looks in a given folder, then picks a random file, without having said file stated in the program itself (like how it was done with switches). 
  I stumbled upon folder enumeration (<a href="http://code.msdn.microsoft.com/windowsapps/Folder-enumeration-sample-33ebd000" rel="nofollow">http://code.msdn.microsoft.com/windowsapps/Folder-enumeration-sample-33ebd000</a>), but I'm uncertain as to how to implement it in my given scenario. </p>
