title: Regex removing double/triple comma in string
body: <p>I need to parse a string so the result should output like that:</p>
  
  <pre><code>"abc,def,ghi,klm,nop"
  </code></pre>
  
  <p>But the string I am receiving could looks more like that:</p>
  
  <pre><code>",,,abc,,def,ghi,,,,,,,,,klm,,,nop"
  </code></pre>
  
  <p>The point is, I don't know in advance how many commas separates the words.<br>
  Is there a regex I could use in C# that could help me resolve this problem?</p>
