title: Elegant way to make whitespace string
body: <p>Is there an elegant way to make <strong>whitespace</strong> string.
  To be more precise, I'm looking for solution similar to following:</p>
  
  <p>For an empty string I could write</p>
  
  <pre><code>string emptyString = "";
  </code></pre>
  
  <p>but instead I use this far more discriptive way</p>
  
  <pre><code>string emptyString = string.Empty;
  </code></pre>
