Linq to return ALL pairs of elements from two lists?

Question

Given lists l1 = {1, 2} and l2 = {4, 5, 6 } I want to get a new list that has elements:

rez = { {1, 4}, {1, 5}, {1, 6}, {2, 4}, {2,         


        

Answer 1

Great article by Eric Lippert - see links in other answers. What's even better, this was the first try I did before looking at the answers on this page :)

In short:

var rez = 
    from e1 in l1
    from e2 in l2 
    select new {e1, e2};
