C# || How To Remove All Whitespace From A String Using C#

May 12, 2021 admin No comments

The following is a module with functions which demonstrates how to remove all whitespace from a string using C#.

1. Remove All Whitespace

The example below demonstrates the use of ‘Utils.Extensions.RemoveWhitespace‘ to remove all whitespace from a string.





		
		
			1. Remove All Whitespace
			
C#
			
			// Remove All Whitespace

using Utils;

var word = $@"
        This document

        uses 3 other documents ";

// Remove whitespace from the string
var result = word.RemoveWhitespace();

Console.WriteLine(result);

// expected output:
/*
    Thisdocumentuses3otherdocuments
*/

using Utils;
 
var word = $@"
        This document
 
        uses 3 other documents ";
 
// Remove whitespace from the string
var result = word.RemoveWhitespace();
 
Console.WriteLine(result);
 
// expected output:
/*
    Thisdocumentuses3otherdocuments
*/

2. Utils Namespace

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