title: NUnit C# syntax for exception handling
body: <p>I need to write tests for some collection of enum values.
  When using part of them I expect an exception and my test need to handle that.</p>
  
  <p>I can write test method with <code>[ExpectedException]</code> and param of my enum value.
  I can write method which uses foreach to enumerate enum values which are expected to raise an exception. But in this case i think first exception will be raised and rest enum values wont be checked.</p>
  
  <p>How to correctly enumerate enum values and check exception with single or 2 maybe methods ?</p>
  
  <p>I just dont want to have one new method for each enum value i need to check.</p>
