body: <p>As the title says how does specflow handle <a href="https://stackoverflow.com/questions/1996426/pass-multiple-optional-parameters-to-a-c-sharp-function">this</a></p>
  
  <pre><code>x = AddUp(2, 3)
  x = AddUp(5, 7, 8, 2)
  x = AddUp(43, 545, 23, 656, 23, 64, 234, 44)
  </code></pre>
  
  <p>The link I gave is how it is usually done. 
  What i want to know is what should the annotation on the top be?</p>
  
  <pre><code>[Then(@"What should I write here")]
  public static void AddUp(params int[] values)
  {
     int sum = 0;
     foreach (int value in values)
     {
        sum += value;
     }
     return sum;
  }
  </code></pre>
