title: Validating a console input
body: <p>My mind has gone completely blank as to how to validate a null text value</p>
  
  <p>All I need to do is check if an entered value is blank, if so ask again without continuing.</p>
  
  <pre><code>Console.WriteLine("Venue Name - ");
  String venName = Console.ReadLine();
  </code></pre>
  
  <p>I can think how to do it with various loops and IF statements, but I'm sure there's a far more efficient way, please help. </p>
