title: Create a comma-separated strings in C#
body: <p>I have an object which holds many values, and some of them (not all values from the object) need to be put in a <a href="https://en.wikipedia.org/wiki/Comma-separated_values" rel="noreferrer">CSV</a> string. My approach was this:</p>
  <pre><code>string csvString = o.number + &quot;,&quot; + o.id + &quot;,&quot; + o.whatever ....
  </code></pre>
  <p>Is there is a better, more elegant way?</p>
