How to get the difference of two list in C# using LINQ

I've two lists like

List<String> LISTONE=new List<String>()

and 

List<String> LISTTWO=new List<String>()

and which contains

LISTONE   "A"
          "B"
          "C"
LISTTWO   "A"
          "D"
          "E"

and the required out put is

LISTTEMP  "B"   
          "C"
          "D"
          "E"

is there any way to do this using LINQ

LISTONE.Except(LISTTWO).Union(LISTTWO.Except(LISTONE)) //.Distinct()?

EDIT: The Union method implements Distinct behaviour, so Distinct would be redundant.

Assuming you want "All elements which do not appear in both lists", in which case, as my note above mentions, "B" should also be in there. this is the linq'ed answer.

one.Concat(two).Except(one.Intersect(two))

It can be done using Except() and Concat() LINQ methods:

LISTONE.Except(LISTTWO).Concat(LISTTWO.Except(LISTONE))
