IIntStream intStream = new IntStreamBuilder().Size(5).Build(); int[] values = intStream.ToArray();
IIntStream intStream = new IntStreamRange(10, 20); int sum = intStream.Filter(n => n % 2 == 0).Sum();This code creates an IIntStream object that produces a sequence of integers from 10 to 20 and then filters out only even numbers. The resulting stream is summed up to get the total of the even numbers in the range. Overall, IIntStream is a useful interface for manipulating a sequence of integers in C# code. It is part of the System.Linq library, which provides many other powerful features for working with sequences in C#.
