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

May 12, 2021 admin No comments

The following is a module with functions which demonstrates how to remove excess whitespace from a string, replacing multiple spaces into just one using C#.

1. Remove Excess Whitespace

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





		
		
			1. Remove Excess Whitespace
			
C#
			
			// Remove Excess Whitespace

using Utils;

var word = @"
        This   document 

        uses 3 other documents ";

// Creates single space string
var result = word.ToSingleSpace();

Console.WriteLine(result);

// expected output:
/*
    This document uses 3 other documents
*/

using Utils;
 
var word = @"
        This   document 
 
        uses 3 other documents ";
 
// Creates single space string
var result = word.ToSingleSpace();
 
Console.WriteLine(result);
 
// expected output:
/*
    This document uses 3 other documents
*/

2. Utils Namespace

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