How do I construct an array of doubles 'in a smart way'? I need it filled with 10-ish values like this,
var d = new double[] { -0.05, 0.0, 0.05};
but would prefer a more dynamic building like this
var d = new List<double>();
for (var dd = -0.05; dd < 0.05; dd += 0.05)
{
d.Add(dd);
}
It looks chunky though and commands too much attention in my code compared to the rather mundane service performed.
Can I write it smarter?

Try Enumerable.Range:
int n = 7;
double step = 0.05;
double[] d = Enumerable
.Range(-n / 2, n)
.Select(i => i * step)
.ToArray();
Console.Write(string.Join("; ", d));
Outcome
-0.15; -0.1; -0.05; 0; 0.05; 0.1; 0.15
If n = 3 then we'll get
-0.05; 0; 0.05
