title: list of ints to array in c#
body: <p>I have a list of ints called <code>MyList</code>. In javascript, when we call <code>toString</code> on an array of numbers, it converts it into a string with each number separated with commas; I'm looking to do the same with in C#.</p>
  
  <p>I tried calling <code>.ToString</code>() to the list but it's returning the type of the list. I'm thinking of a loop that iterates over the list and add each element to a stringbuilder, along with the comma, and then .ToString() the stringbuilder.</p>
  
  <p>Is that the best way to do it?</p>
  
  <p>Thanks.</p>
