I want to use linq to merge two list, and the with the linq I want to remove the duplicates, how to remove duplicate values after merging the to list in linq. I am assuming you probably call the distinct method after

How to merger ListOne and ListTwo below.

For instance, if one list contains:

List ListOne

"Bob"
"Bill"
"Fred"
"Jim"

and another list contains:

List ListTwo

"Bob"
"Fred"

the result will be:

"Bill"
"Jim"

Try the following:

using System;
using System.Collections.Generic;
using System.Linq;

class Test
{
static void Main()
{
List ListOne = new List
{
"Bob",
"Bill",
"Fred",
"Jim",
};

List ListTwo = new List
{
"Bob",
"Fred",
};

List ListThree = ListOne.Except(ListTwo).Union(ListTwo.Except(ListOne)).ToList();
foreach(string s in ListThree) Console.WriteLine(s);
Console.ReadKey();
}
}
