Joining two lists together
<p>If I have two lists of type string (or any other type), what si a quick way of joining the two lists?</p>

<p>EDIT: Order should stay the same. Duplicates removed (though every item in both links are unique). I didn't find much on this when googling and didn't want to implement any .NET interfaces for speed of delivery.</p>

<p>Thanks</p>
