Is it possible to list all permutations of two IEnumerables using linq

Question

I could do this with loops, but is there a way to take two IEnumerables, list all possible permutations, and select an object containing the permutation? I feel that this “should” be possible, but I'm not sure which operators to use.

Thanks james

Answer 1

Are you talking about what is basically a Cartesian compound? You can do something like

var query = from item1 in enumerable1 from item2 in enumerable2 select new { Item1 = item1, Item2 = item2 } 

Answer 2

Anthony's answer is correct. Equivalent to extension method:

 var query = enumerable1.SelectMany( x => enumerable2, (item1, item2) => new { Item1 = item1, Item2 = item2 } ); 

or

 var query = enumerable1.SelectMany( item1 => enumerable2.Select(item2 => new { Item1 = item1, Item2 = item2 }); );
