RangeExtensions
This package allows you to use 0..100
in foreach
expressions and implements RangeEnumerable
that supports a variety of LINQ-like operations as well as ICollection<int>
and IEnumerable<int>
.
- Correctness is verified against standard
IEnumerable<int>
andEnumerable.Range
behavior; - Performance is hand tuned to produce efficient native code with no allocations as long as
RangeEnumerable
isn't boxed (same applies to enumerator). However, even when boxed it is still faster thanEnumerable.Range
.
Features
Range enumeration
foreach (var i in ..100) // you can write 0..Length as just ..Length
{
Console.WriteLine(i);
}
Reverse range enumeration
for (var i = 100 - 1; i >= 0; i--)
{
Console.WriteLine(i);
}
// Can be written as
foreach (var i in 100..0)
{
Console.WriteLine(i);
}
Collecting to array or list
var numbers = (0..100).ToArray();
IEnumerable<int>
(some methods have bespoke implementations for performance)
var enumerable = (..100).AsEnumerable();
var sum = enumerable.Sum();
var count = enumerable.Count();
var average = enumerable.Average();
var firstTen = enumerable.Take(10);
var reversed = enumerable.Reverse();
// and others.
Performance
In short: 10x fast vs Enumerable.Range()
and as fast as a plain for
loop (there's small fixed overhead to check range correctness).
