title: C# Windows forms app. Override toString question
body: <p>Is it possible to give the Override ToString method the return value of another method?
  So in the screenshot you will see a override tostring, which displays the Radius * the PI value.</p>
  <p>And I want to say:</p>
  <p>Radius * PI value = return value</p>
  <p>(return value = &quot;oppervlakte&quot;)</p>
