Loading, updating, and saving time value?
<p>I'm creating a game you can load and save. I wanted to include details on how long the user has played. I have something like the following to determine the time they spent on the game. How do I save and load their total time? I know I want to put that value into <code>Properties.Settings</code> to load and save but I'm at a loss for how I should execute that.</p>

<pre><code>private void Form1_Load(object sender, EventArgs e)
{
   //Load previous time
   stopWatch.Start();
}

private void Form1_KeyUp(object sender, KeyEventArgs e)
{
   if (e.KeyCode == Keys.Enter &amp;&amp; pbPlayer.Bounds.IntersectsWith(pnlSave.Bounds))
      {
       string timePlayed;
       stopWatch.Stop();
       TimeSpam timeSpan = stopWatch.Elapsed; //+ Their previous time
       timePlayed = string.Format("{0:D2}:{1:D2}:{2:D2}", timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds);
       MessageBox.Show("You've played for" + timePlayed + ". Game saved!"
       }
       //Save their total time
 }
</code></pre>
