title: c# get value list from excel file
body: <p>I'm working on a dll for Excel file.
  In the dll I want to do a method in which the client will enter the row to get the list from, and then enter the column from and to get list.
  something like:
  public List GetValueList(int inRow, string fromColumn, string toColumn)</p>
  
  <p>The problem is- how can I get do it? in Excel there are columns like "AZX", "AA" and so on... I can't just do "fromColumn++".</p>
  
  <p>Any ideas? I hope I explained myself.</p>
