I am having a list which contains 243 strings. I want to split the list into several smaller lists containing 20 strings each. Obviously, the last list should have 3 strings. I want the format to be List>.

How do accomplish this with linq och lambda?

To the ones who cares: When I have my lists, i will use foreach on them to call an API with only so many string at a time.

NuGet "System.Reactive" and then do `list.Buffer(20)`. – Enigmativity Jan 16 '19 at 07:23
Thank you Sweeper, that linked did the work. I paste the code that I finally used: var result = source .Select((x, i) => new { Index = i, Value = x }) .GroupBy(x => x.Index / 20) .Select(x => x.Select(v => v.Value).ToList()) .ToList(); – Martin Nilsson Jan 16 '19 at 08:12
