title: C# import an excel column into ComboBox dropdown values
body: <p>I have a spread sheet with values that I would like to fill into drop down boxes in Windows forms using C#.  Some of these values contain 100's of entries and I don't want to fill them in by hand or embed them in the source code.  </p>
  
  <p>I also need to be able to add and remove values from the combo-box's once they are entered so I believe this rules out binding it to a data set.</p>
  
  <p>How would one do this?</p>
