title: Use a MessageBox to get a user input?
body: <p>Sorry for the strange suggestion in the title...</p>
  
  <p>I'm looking to try and get a single piece of information from a user, and I was wondering if there was a variant of <code>MessageBox</code> that would grab a single piece of data, like a number as a parameter for a list size.</p>
  
  <pre><code>int listSize = Convert.ToInt32(MessageBox.TextBox.Text);
  </code></pre>
  
  <p>I don't really want to go through the effort of creating a tiny form for this single purpose if I can avoid it.</p>
