Return list of remaining elements in C#

Question

I have two lists:

List<int> data1 = new List<int> {1,2};
List<int> data2 = new List<int>{1,2,3,4};

I want to create a new list:

List<int> data3

which intersects data1 and data2 and and contains elements as {3,4}

Answer 1

You can try to use Except

var result = data2.Except(data1);
