title: Select Distinct from a list of IEnumerable<T> in .NET 2.0
body: <p>I am trying to filter an IEnumerable object of the duplicate values, so I would like to get the distinct values from it, for example, lets say that it holds days:</p>
  
  <p>monday
  tuesday
  wednesday
  wednesday</p>
  
  <p>I would like to filter it and return:</p>
  
  <p>monday 
  tuesday
  wednesday</p>
  
  <p>What is the most efficient way to do this in .net 2.0?</p>
