The Program in C# Program to Check largest Number among given integers is given below:

using System;

namespace LargestNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello Codeauri Family, enter the number of integers  here you want to compare:");
            int n = Convert.ToInt32(Console.ReadLine());

            int[] numbers = new int[n];
            Console.WriteLine("Enter the integers:");
            for (int i = 0; i < n; i++)
            {
                numbers[i] = Convert.ToInt32(Console.ReadLine());
            }

            int largest = numbers[0];
            for (int i = 1; i < n; i++)
            {
                if (numbers[i] > largest)
                {
                    largest = numbers[i];
                }
            }

            Console.WriteLine("Okay, the largest number is: " + largest);
            Console.ReadLine();
        }
    }
}

Output:

Hello Codeauri Family, enter the number of integers here you want to compare:
Enter the integers:

20540707

20560423
20120292
Okay, the largest number is: 20560423

Pro-Tips💡

Here are the step by step execution of above program:

1. The program starts with the line using System;, which is a directive that includes the System namespace. This namespace contains many classes and methods that are commonly used in C# programs, including the Console class that is used later in the program.
2. The next line namespace LargestNumber defines a namespace for the program, which can be used to organize related classes and avoid naming conflicts with other classes.
3. The following block class Program defines a class called Program that contains the program logic.
4. The method Main(string[] args) is the entry point of the program. This method will be executed when the program is run.
5. The line Console.WriteLine("Hello Codeauri Family, enter the number of integers here you want to compare:"); outputs the text “Hello Codeauri Family, enter the number of integers here you want to compare:” to the console.
6. The next line int n = Convert.ToInt32(Console.ReadLine()); reads a line of text from the console and converts it to an integer, which is stored in the variable n.
7. The line int[] numbers = new int[n]; creates an array of integers with n elements.
8. The following loop for (int i = 0; i < n; i++) prompts the user to enter n integers. The entered integers are stored in the numbers array.
9. The next block of code for (int i = 1; i < n; i++) loops through the numbers array and keeps track of the largest number. The variable largest is initialized with the first element of the numbers array. The loop then checks if each subsequent element is larger than largest, and if so, updates largest with the new largest number.
10. The line Console.WriteLine("Okay, the largest number is: " + largest); outputs the text “Okay, the largest number is: ” followed by the largest number that was found in the previous step.
11. The last line Console.ReadLine(); waits for the user to press the Enter key before closing the console.
