The Program in C# Program to check if an array contains an odd Number is given below:

using System;

namespace OddNumberCheck
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello Codeauri Family, enter the length of the array here to check whether there is an odd number or not!: ");
            int n = int.Parse(Console.ReadLine());
            int[] arr = new int[n];

            Console.WriteLine("Well, enter the elements of the array: ");
            for (int i = 0; i < n; i++)
            {
                arr[i] = int.Parse(Console.ReadLine());
            }

            Console.WriteLine("Enter an odd number to check: ");
            int oddNumber = int.Parse(Console.ReadLine());

            bool found = false;
            for (int i = 0; i < n; i++)
            {
                if (arr[i] == oddNumber)
                {
                    found = true;
                    break;
                }
            }

            if (found)
                Console.WriteLine("Well, the array contains the odd number.");
            else
                Console.WriteLine("The array does not contain the odd number.");

            Console.ReadLine();
        }
    }
}

Output:

Hello Codeauri Family, enter the length of the array here to check whether there is an odd number or not!: 2

Well, enter the elements of the array:
190
199
Enter an odd number to check:
199
Well, the array contains the odd number.

Pro-Tips💡

Here are the step by step execution of above program;

1. The first line “using System;” imports the System namespace which provides access to various classes and methods, including Console.
2. In the namespace “OddNumberCheck” the class “Program” is defined.
3. In the class, the “Main” method is defined, which is the entry point of the program.
4. The program prompts the user to enter the length of the array. This length is stored in the variable “n”.
5. An array “arr” of length “n” is created and initialized.
6. The program prompts the user to enter the elements of the array.
7. The program prompts the user to enter an odd number to check for. This number is stored in the variable “oddNumber”.
8. A variable “found” is initialized to “false”.
9. A for loop iterates over the array and checks if the element is equal to the “oddNumber”. If a match is found, the “found” variable is set to “true” and the loop is exited.
10. The program checks the value of “found” and outputs a message indicating if the array contains the odd number.
11. The program waits for the user to press Enter to close the console.
