title: How to check dictionary is null in VB.NET?
body: <p>Am new to vb.net and doing a work flow in vb.net, i need to check whether a dictionary is null. I have declared a dictionary, but have not assigned any value to it.</p>
  
  <p>When i use <code>IsNothing()</code> method it gives object reference exception. How can i check?</p>
  
  <pre><code>Dim CustDicAs New Dictionary(Of String, Integer)
  CustDic.IsNothing()
  </code></pre>
