An elegant way to create a list <int> just with (int) from and (int) before
I need an elegant way to create a new List<int>
one with integers only.
Example:
var from = 2;
var to = 5;
I want it:
List<int> { 2, 3, 4, 5 };
Of course, I could do it in a simple scheme:
var results = new List<int>();
for (var i = from; i <= to; i++)
{
results.Add(i);
}
But I want a more efficient or elegant way.

Of course use Enumerable.Range
:
var results = Enumerable.Range(2, 4).ToList();
Note that 4
here refers to the number of integers that should be included in the list of results. Therefore, to create the range specified by the from
and variables to
, use:
var results = Enumerable.Range(from, to - from + 1).ToList();
