Group by variable integer range using Linq

Question

I\'m trying to group a set of data based on the range of an integer, by the range does not increase at a fixed interval.

e.g. I have

Item ID Price

Answer 1

How about something like this?

var data = new[] {
    new { Id = 1, Price = 2 },
    new { Id = 1, Price = 10 },
    new { Id = 2, Price = 30 },
    new { Id = 3, Price = 50 },
    new { Id = 4, Price = 120 },
    new { Id = 5, Price = 200 },
    new { Id = 6, Price = 1024 },
};

var ranges = new[] { 10, 50, 100, 500 };

var grouped = data.GroupBy( x => ranges.FirstOrDefault( r => r > x.Price ) );
