title: Throw a format exception C#
body: <p>I'm trying to throw a format exception in the instance someone tries to enter a non-integer character when prompted for their age.           </p>
  
  <pre><code>        Console.WriteLine("Your age:");
          age = Int32.Parse(Console.ReadLine());
  </code></pre>
  
  <p>I'm unfamiliar with C# language and could use help in writing a try catch block for this instance. </p>
  
  <p>Thanks very much. </p>
