title: C#, Copy one bool to another (by ref, not val)
body: <p>I am at a brick wall here. Is it possible to copy one bool to the ref of another. Consider this code . . .</p>
  
  <pre><code>bool a = false;
  bool b = a;
  </code></pre>
  
  <p>b is now a totally separate bool with a value of false. If I subsequently change a, it will have no effect on b. Is it possible to make a = b by ref? How would I do that?</p>
  
  <p>Many thanks </p>
