title: Delete and add values to enum .NET
body: <p>I've searched a lot but couldn't find how to delete and add values from/to enum in .NET</p>
  
  <p>Let's say we have enum like this:</p>
  
  <pre><code>Public Enum Coordinates
  x
  y
  z
  End Enum
  </code></pre>
  
  <p>What I need is the enum to become like this:</p>
  
  <pre><code>Public Enum Coordinates
  x
  y
  End Enum
  </code></pre>
  
  <p>Any help will be appreciated.</p>
