In this post I am going to show you how to generate fiboancci number series using Linq.What is Fibonacci series :

**public static IEnumerable<int> Fib(int n) { List<int> fibs = new List<int>(); Enumerable.Range(0, n) .ToList() .ForEach(f => fibs.Add((f <= 1 ? 1 : fibs[f - 2] + fibs[f - 1]))); return fibs; }***The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... The next number is found by adding up the two numbers before it.*
