title: Find index of item in a multidimensional array
body: <p>If I have a multidimensional array:</p>
  
  <pre><code>Dim test(,,) As String
  </code></pre>
  
  <p>How can I loop through the array to find if another variable is contained in the second dimension of the array?</p>
  
  <p>Obviously, this won’t work:</p>
  
  <pre><code>Dim x As Integer = test.IndexOf(otherVariable)
  </code></pre>
