c# - How to get ranged by index with LINQ allow to take previous or next items? -


for example want take next 3 items this

private ienumerable<t> indexrange<t>(ilist<t> source, int start, int end) {      return source.skip(start).take(end); }

but need able take previous 3 items if need it. how possible? example: indexrange(source, 15, 12);

your code wrong. should be:

return source.skip(start).take(end - start + 1);

to you're asking be:

return source.skip(math.min(start, end)).take(math.abs(end - start) + 1);

note code assumes both start , end inclusive.
