Intersect a collection of collections in LINQ
- by Larsenal
I've got a list of lists which I want to intersect:
List<List<int>> input = new List<List<int>>();
input.Add(new List<int>() { 1, 2, 4, 5, 8 });
input.Add(new List<int>() { 3, 4, 5 });
input.Add(new List<int>() { 1, 4, 5, 6 });
Output should be
{ 4, 5 }
How can this be accomplished in a terse fashion?
