VB.NET || How To Remove Excess Whitespace From A String Using VB.NET

November 24, 2020 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 VB.NET.

1. Remove Excess Whitespace

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





		
		
			1. Remove Excess Whitespace
			
Visual Basic .NET
			
			' Remove Excess Whitespace

Imports Utils

Dim word = "
    This   document 

    uses 3 other documents "

' Creates single space string
Dim result = word.ToSingleSpace

Debug.Print(result)

' expected output:
'    This document uses 3 other documents

						' Remove Excess Whitespace
 
Imports Utils
 
Dim word = "
    This   document 
 
    uses 3 other documents "
 
' Creates single space string
Dim result = word.ToSingleSpace
 
Debug.Print(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!
