I've been trying to use a lambda for this :
var y = from r in rs.Returns from z in r.Tags where z.Name.Contains(c) select r;
I tried var r = rs.Returns.Where(x=>x.Tags.Where(x=>x.Name.Contains(c)));
but it didnt work. What is the correct lambda so I dont have to use y
& z
You need a SelectMany
to translate the second "from" clause:
var y = rs.Returns
.SelectMany(r => r.Tags, (r, z) => new { r, z })
.Where(pair => pair.z.Name.Contains(c))
.Select(pair => pair.r);
That's a pretty direct translation. Another alternative would be to use:
var y = rs.Returns.Where(r => r.Tags.Any(z => z.Name.Contains(c)));
