Getting pair-set using LINQ

by

The most elegant way with LINQ: list.Zip(list.Skip(1), Tuple.Create)

A real-life example: This extension method takes a collection of points (Vector2) and produces a collection of lines (PathSegment) needed to ‘join the dots’.

static IEnumerable<PathSegment> JoinTheDots(this IEnumerable<Vector2> dots)
{
    var segments = dots.Zip(dots.Skip(1), (a,b) => new PathSegment(a, b));
    return segments;
}
