title: using a global variable on C#
body: <p>So I have to use this <code>void</code></p>
  
  <pre><code>static void PerformOption(int option)
  </code></pre>
  
  <p>However I want this <code>int</code> option to be able to be used by other <code>void</code>s as well.
  I know this could be done by deleting inside of brackets and assigning a <code>static int</code> but I have to use <code>int</code> option for this <code>void</code>, so I cannot change this one.</p>
  
  <p>So how can I make option as global variable?</p>
