title: Send variables to other classes
body: <p>Can I have a function that checks if true or false and send my verbal to other classes?</p>
  
  <p>I tried:</p>
  
  <pre><code>public class Func
  {
      public static bool CheckDate(string number)
      {
          string new_number = number.ToString();
          if (new_number.Length==8)
          {
             string yyyy = new_number.Substring(0, 4);
             string mm = new_number.Substring(4, 2);
             string dd = new_number.Substring(6, 2);
             return true;
          }
          else
          {
              return false;
          }
      }
  }
  </code></pre>
  
  <p>I want to send the verbal <code>yyyy</code>, <code>mm</code>, <code>dd</code> to my <code>Program.cs</code> class.</p>
  
  <p>What should I do?</p>
