title: How to loop while the condition is false instead of true? C#
body: <p>I am trying to convert a string into an integer while also validating</p>
  
  <pre><code>string multiplierstr;
  do {
      multiplierstr = Console.ReadLine();
  } while (Int32.TryParse(multiplierstr, out multiplier));
  </code></pre>
  
  <p>However, it loops when the input is an integer, and I'd like it to loop when the input is a string, while still using the TryParse method. Any way to do it?</p>
