title: Converting a generic list to a CSV string
body: <p>I have a list of integer values (List) and would like to generate a string of comma delimited values. That is all items in the list output to a single comma delimted list.</p>
  
  <p>My thoughts...
  1. pass the list to a method.
  2. Use stringbuilder to iterate the list and append commas
  3. Test the last character and if it's a comma, delete it.</p>
  
  <p>What are your thoughts? Is this the best way?</p>
  
  <p>How would my code change if I wanted to handle not only integers (my current plan) but strings, longs, doubles, bools, etc, etc. in the future? I guess make it accept a list of any type.</p>
