C# || How To Convert A String To Byte Array & Byte Array To String Using C#

May 08, 2021 admin No comments

The following is a module with functions which demonstrates how to convert a string to a byte array and a byte array to a string using C#.

1. String To Byte Array

The example below demonstrates the use of ‘Utils.Extensions.GetBytes‘ to convert a string to a byte array. The optional parameter allows to specify the encoding.





		
		
			1. String To Byte Array
			
C#
			
			// String To Byte Array

using Utils;

var text = $"My Programming Notes!";
var bytes = text.GetBytes();

// Do something with the byte array

						// String To Byte Array
 
using Utils;
 
var text = $"My Programming Notes!";
var bytes = text.GetBytes();
 
// Do something with the byte array

2. Byte Array To String

The example below demonstrates the use of ‘Utils.Extensions.GetString‘ to convert a byte array to a string. The optional parameter allows to specify the encoding.





		
		
			2. Byte Array To String
			
C#
			
			// Byte Array To String

using Utils;

var text = $"My Programming Notes!";
var bytes = text.GetBytes();
var str = bytes.GetString();

// Do something with the string

var text = $"My Programming Notes!";
var bytes = text.GetBytes();
var str = bytes.GetString();
 
// Do something with the string

3. Utils Namespace

The following is the Utils Namespace. Include this in your project to start using!
