This should just be a simple count:

C#

var myEnumerable = [new {id=1,arr=[1,2,3,4]},new {2,[1,2,3]},new {3,[1,2,3,4,5,6]}];

var countedFlat = myEnumerable.Select(a=>new {a.id,count = a.arr.Count()});

foreach(var anon in countedFlat)
{
  Console.WriteLine("id:{0} - count:{1}",anon.id,anon.count);
}

output

id:1 - count:4
id:2 - count:3
id:3 - count:6
