Google for "enumerable.range step" and you should be able to come upon alternate implementations of Enumerable.Range that provide stepped ranges. Then you can just do a
Parallel.ForEach(BetterEnumerable.SteppedRange(fromInclusive, toExclusive, step), ...)
If google isn't working, implementation should be something like this:
public static class BetterEnumerable {
public static IEnumerable<int> SteppedRange(int fromInclusive, int toExclusive, int step) {
for (var i = fromInclusive; i < toExclusive; i += step) {
yield return i;
}
}
}
Alternately if "yield return" gives one the heebie jeebies, you can always just create a regular old list in-place:
var list = new List<int>();
for (int i = fromInclusive; i < toExclusive; i += step) {
list.Add(i);
}
Parallel.ForEach(list, ...);
This should be easily translatable to VB if that's a requirement.
