title: What can I do with a protected/private static variable?
body: <p>I see I can write :</p>
  
  <pre><code>protected static
  </code></pre>
  
  <p>in my C# class (in my case, an aspx.cs). As well as :</p>
  
  <pre><code>private static
  </code></pre>
  
  <p>What does it means? Static is accessible everywhere. Why protected/private? </p>
