WebThe cartesian products of sets can be considered as the product of two non-empty sets in an ordered way. The final product of the sets will be a collection of all ordered pairs obtained by the product of the two non-empty sets. In an ordered pair, two elements are taken from each of the two sets. WebA Cartesian product of the two lists would be the following: { (A,1), (A,2), (A,3), (B,1), (B,2), (B,3), (C,1), (C,2), (C,3)} Let us see how to achieve something similar in LINQ using the SelectMany method Needless to say, this peice of code is the key to generating cartesian product in LINQ: gs cookies samoas
