title: How to use application settings in .NET 3.5 Windows Forms
body: <p>I am trying to store a type of <code>System.Collection.Queue</code>. The queue will only contain strings. The issue is that when I attempt to use it, it is always Null. </p>
  
  <pre><code>Settings.Default.CorrectionsDescription.Enqueue(textString);
  </code></pre>
  
  <p>I get the following error.</p>
  
  <blockquote>
    <p>Object reference not set to an instance of an object.</p>
  </blockquote>
  
  <p>I have gotten <code>StringCollection</code> to work fine, but I need a <a href="http://en.wikipedia.org/wiki/FIFO" rel="nofollow noreferrer">FIFO</a> queue.</p>
  
  <p>How do you initialize the queue, in the Settings or through code? When I tried, it gave the error that it is read only.</p>
