In this article, we will explore the binary encoding in C# that shows how to convert strings into their binary representation.

How to Convert Strings to Binary Encode in C#

The below C# program converts a user provided string into its binary representation:

using System;
using System.Text;

class Program
    static void Main()
        Console.Write("Enter a string: ");
        string input = Console.ReadLine();

        // Convert string to binary
        string binaryRepresentation = StringToBinary(input);

        // Display the result
        Console.WriteLine($"Binary representation: {binaryRepresentation}");

    static string StringToBinary(string input)
        byte[] bytes = Encoding.ASCII.GetBytes(input);
        StringBuilder binary = new StringBuilder();

        foreach (byte b in bytes)
            binary.Append(Convert.ToString(b, 2).PadLeft(8, '0'));

        return binary.ToString();

The above program starts with prompting the user to enter a string. Once the user enters the string, the StringToBinary method gets the user input and converts it into a binary representation. It uses the Encoding.ASCII.GetBytes method to get the ASCII values of each character in the string. Then, it converts each ASCII value to an 8-bit binary representation. Lastly, the binary representation is displayed to the user.


Enter a string:

Binary representation: 0100100001100101011011000110110001101111

Enter a string:

Binary representation: 0100001001101001001100001101001101101001
