title: TokenStream doesn't exist in ANTLR parser C# implementation
body: <p>I'm currently following the "Building a Translator with a Listener" tutorial of "The Definitive ANTLR 4 Reference", but I'm using C# and translate the examples into that.</p>
  
  <p>However, I got stuck at a variable declaration of the type "TokenStream" which I seem to be missing in C# (I can't find it anywhere). The tutorials Java code says</p>
  
  <pre><code>TokenStream tokens = parser.getTokenStream();
  </code></pre>
  
  <p>Beyond the missing TokenStream type in C#, I can't even find an equivalent method of the Parser class.
  How is this done with the C# implementation of ANTLR?</p>
