title: Detect particular tokens in a string. C#
body: <p>I have a very large string (HTML) and in this HTML there is particular tokens where all of them starts with "#" and ends with "#" </p>
  
  <p>Simple Eg</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
        &lt;p&gt;Hi #Name#, You should come and see this #PLACE# - From #SenderName#&lt;/p&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I need a code that will detect these tokens and will put it in a list.
  0 - #Name#
  1 - #Place#
  2 - #SenderName#</p>
  
  <p>I know that I can use Regex maybe, anyway have you got some ideas to do that?</p>
