title: Create a List of pairs in .net
body: <p>I need to create a <code>List&lt;&gt;</code> of pairs of my classes. such as:
  <code>List&lt;Class1, Class2&gt;</code></p>
  
  <p>How would you do it?
  I can not use the "Pair" datatype because it's in system.web.UI.</p>
  
  <p>Would you create a list of arrays?
  Create a struct of both classes and add them to a list?</p>
  
  <p>Is there another way I don't know of and I'm just a noob?</p>
  
  <p>Note:
  I don't want the list to auto-sort in any way.</p>
