title: C# After I save a .csv in Excel, how do I open it?
body: <p>I did a little research, and an unsure if I should be using</p>
  
  <blockquote>
    <p>the Microsoft.Office.Interop.Excel</p>
  </blockquote>
  
  <p>Just to clarify with the example: I'm taking a .txt, and doing stuff, then saving it as a .CSV (Comma Separated Values).  I want to then open it (on button click or something...)</p>
  
  <p>How can this be done?</p>
