title: Find word (not containing substrings) in comma separated string
body: <p>I'm using a linq query where i do something liike this:</p>
  
  <pre><code>viewModel.REGISTRATIONGRPS = (From a In db.TABLEA
      Select New SubViewModel With {
      .SOMEVALUE1 = a.SOMEVALUE1,
      ...
      ...
      .SOMEVALUE2 = If(commaseparatedstring.Contains(a.SOMEVALUE1), True, False)
      }).ToList()
  </code></pre>
  
  <p>Now my Problem is that this does'n search for words but for substrings so for example:</p>
  
  <p>commaseparatedstring = "EWM,KI,KP"
  SOMEVALUE1 = "EW"</p>
  
  <p>It returns true because it's contained in EWM?</p>
  
  <p>What i would need is to find words (not containing substrings) in the comma separated string!</p>
