and if Start=1 and Count=10 then { 1, 3, 5, 7, 9 }

The continuous value can be get like

var a = Enumerable.Range(0,10).ToList();

but how to get the alternate values?

Answer 1

Halving the number of items that Range should generate (its second parameter) and then doubling the resulting values will give both the correct number of items and ensure an increment of 2.

Enumerable.Range(0,5).Select(x => x * 2)
