Question

I want to remove items of a Jagged array using indizes.

int[] toRemove; (e.g, {0, 1})

int[][] MainArray (e.g. { [0] {...}, [1] {...}, [2] {...}}

Expected result

int[][] result (e.g. {[2] {...}}

From the MainArray how to remove the items which having indexes from the toRemove list?

Is there an efficient way using LINQ?

Answer 1

Hopefully this gives the expected result:

var notInToRemove = MainArray
    .Where((arr ,index) => !toRemove.Contains(index)).ToArray();
