In this tutorial I will show how to find Odd numbers in C#. I have given two example first example is very simple.
- First example I have used simple for loop to find Odd numbers.
- Second example I have created a Linq for finding Odd Numbers.
Both the examples check reminder of a number. If the reminder not 0 then the number must be odd number.
Method 1:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | class Program { static void Main(string[] args) { List<int> numbers = new List<int>() { 10,12,20,21,23,25,26,23,20,17,85,60,30,35 }; Console.WriteLine("\nAll Numbers"); for(int i = 0; i < numbers.Count; i++) { Console.Write("{0} ",numbers[i]); } Console.WriteLine("\n\nOdd Numbers"); for (int i = 0; i < numbers.Count; i++) { if(numbers[i] % 2 != 0) Console.Write("{0} ", numbers[i]); } Console.ReadLine(); } } |
Method 2:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | class Program { static void Main(string[] args) { List<int> numbers = new List<int>() { 10,12,20,21,23,25,26,23,20,17,85,60,30,35 }; Console.WriteLine("\nAll Numbers"); numbers.ForEach(number => Console.Write("{0} ",number)); Console.WriteLine("\n\nOdd Numbers"); var oddNumbers = numbers.Where(number => number % 2 != 0).ToList(); oddNumbers.ForEach(number => Console.Write("{0} ", number)); Console.ReadLine(); } } |
Output:
