Decimal to Binary Conversion in C# with Examples

 Admin     August 11, 2020     C#, Interview Question, Programming, Programs     No comments   

In this article, I am going to discuss the Decimal to Binary Conversion in C# with some examples. Please read our previous article where we discussed the Sum of Digits of a given number Program in C# in many different ways. In C#, we can easily convert any decimal number (base-10 (i.e. 0 to 9)) into binary number (base-2 (i.e. 0 or 1)). As part of this article, we are going to discuss the following pointers.
  1. What are Decimal Numbers?
  2. What are Binary Numbers?
  3. How to Convert Decimal to Binary in C#?
What are Decimal Numbers?
The Decimal numbers are the numbers whose base is 10. That means the decimal numbers are range from 0 to 9. Any combination of such digits (digits from 0 to 9) is a decimal number such as 2238, 1585, 227, 0, 71, etc.

What are Binary Numbers?
The Binary numbers are the numbers whose base is 2. That means the binary numbers can be represent using only two digits i.e. 0 and 1. So, any combination of these two numbers (i.e. 0 and 1) is a binary number such as 101, 10o1, 111111, 10101, etc.

Let us have a look which shows the decimal number along with its binary representation.
Decimal to Binary Conversion in C#

Algorithm: Decimal to Binary Conversion

Step1: First, divide the number by 2 through modulus (%) operator and store the remainder in an array
Step2: Divide the number by 2 through division (/) operator.
Step3: Repeat step 2 until the number is greater than zero.


Program: Decimal to Binary Conversion in C#
using System;
namespace LogicalPrograms
{
    public class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter the Decimal Number : ");
            int number = int.Parse(Console.ReadLine());
            int i;
            int[] numberArray = new int[10];
            for (i = 0; number > 0; i++)
            {
                numberArray[i] = number % 2;
                number = number / 2;
            }
            Console.Write("Binary Represenation of the given Number : ");
            for (i = i - 1; i >= 0; i--)
            {
                Console.Write(numberArray[i]);
            }
            Console.ReadKey();
        }
    }
}
Output:
Decimal to Binary Conversion Program in C#

Let us see another way of doing the conversion from Decimal to Binary in C#.
In the following program, we created a string variable to hold the binary representation of the Decimal number.
using System;
namespace LogicalPrograms
{
    public class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter the Decimal Number : ");
            int number = int.Parse(Console.ReadLine());
            
            string Result = string.Empty;
            for (int i = 0; number > 0; i++)
            {
                Result = number % 2 + Result;
                number = number / 2;
            }
            Console.WriteLine($"Binary Represenation of the given Number : {Result}");
            
            Console.ReadKey();
        }
    }
}
Output:
Conversion from Decimal to Binary in C#

In the next article, I am going to discuss the Binary to Decimal Conversion Program in C# with some examples. Here, in this article, I try to explain the Decimal to Binary Conversion in C# with some examples.

Summary:
I hope this post will be helpful to understand Decimal to Binary Conversion in C#
