title: How to check if one value of an object is null
body: <p>I have an object with multiple strings.<br />
  Is there a way to check if one of the values is null or all values are set?<br />
  Or do I have to do it like this:</p>
  <pre><code>if (!string.IsNullOrWhiteSpace(object.string1) || !string.IsNullOrWhiteSpace(object.string2) || !string.IsNullOrWhiteSpace(object.string3))
  {
  
  }
  </code></pre>
