title: Is it possible to access backing fields behind auto-implemented properties?
body: <p>I know that I can use the verbose syntax for properties:</p>
  
  <pre><code>private string _postalCode;
  
  public string PostalCode
  {
      get { return _postalCode; }
      set { _postalCode = value; }
  }
  </code></pre>
  
  <p>Or I can use auto-implemented properties.</p>
  
  <pre><code>public string PostalCode { get; set; }
  </code></pre>
  
  <p>Can I somehow access the backing field that is behind the auto-implemented property? (In this example that would be _<strong>postalCode</strong>). </p>

  <p><strong>Edit</strong>: My question is not about design, but rather about, let's say, theoretical ability to do so.</p>
