title: How to remove the first element in an array?
body: <p>I have an array:  </p>
  
  <pre><code>arr[0]="a"  
  arr[1]="b"  
  arr[2]="a"  
  </code></pre>
  
  <p>I want to <strong>remove</strong> only <code>arr[0]</code>, and <strong>keep</strong> <code>arr[1]</code> and <code>arr[2]</code>.<br>
  I was using:  </p>
  
  <pre><code>arr= arr.Where(w =&gt; w != arr[0]).ToArray();  
  </code></pre>
  
  <p>Since <code>arr[0]</code> and <code>arr[2]</code> have the same value ("a"), the result I'm getting is only <code>arr[1]</code>.  </p>
  
  <p>How can I return both <code>arr[1]</code> and <code>arr[2]</code>, and only remove <code>arr[0]</code>?</p>
