title: C# dictionary - one key, many values
body: <p>I want to create a data store to allow me to store some data.</p>
  <p>The first idea was to create a dictionary where you have one key with many values, so a bit like a one-to-many relationship.</p>
  <p>I think the dictionary only has one key value.</p>
  <p>How else could I store this information?</p>
