In this C# program, we will learn how to write a program to print a Fibonacci series.

In mathematics, the Fibonacci numbers, commonly denoted ** Fn** form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is,

** F_{0}=0 **and

And

*F _{n}=F_{n-1} + F_{n-2}*

Example of Fibonacci Series is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and so on.

Here is the code of the program to print a Fibonacci series:

```
using System;
namespace TutorialsrackPrograms
{
class Program
{
//Program to print a Fibonacci Series
static void Main(string[] args)
{
int a = 0, b = 1, c = 0;
Console.Write("Enter The Number: ");
int len = Convert.ToInt16(Console.ReadLine());
Console.WriteLine();
Console.Write("Fibonacci Series:\t");
Console.Write("{0} {1}", a, b);
for (int i = 2; i < len; i++)
{
c = a + b;
Console.Write(" {0}", c);
a = b;
b = c;
}
Console.Read();
}
}
}
```

Enter The Number: 10

Fibonacci Series: 0 1 1 2 3 5 8 13 21 34
