title: IsNullOrEmpty equivalent for Array? C#
body: <p>Is there a function in the .NET library that will return true or false as to whether an array is null or empty? (Similar to <code>string.IsNullOrEmpty</code>).</p>
  
  <p>I had a look in the <code>Array</code> class for a function such as this but couldn't see anything.</p>
  
  <p>i.e.</p>
  
  <pre><code>var a = new string[]{};
  string[] b = null;
  var c = new string[]{"hello"};
  
  IsNullOrEmpty(a); //returns true
  IsNullOrEmpty(b); //returns true
  IsNullOrEmpty(c); //returns false
  </code></pre>
