VB.NET || How To Remove All 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 all whitespace from a string using VB.NET.

1. Remove All Whitespace

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





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

Imports Utils

Dim word = "
        This   document 

        uses 3 other documents "

' Remove whitespace from the string
Dim result = word.RemoveWhitespace

Debug.Print(result)

' expected output:
'    Thisdocumentuses3otherdocuments

Imports Utils
 
Dim word = "
        This   document 
 
        uses 3 other documents "
 
' Remove whitespace from the string
Dim result = word.RemoveWhitespace
 
Debug.Print(result)
 
' expected output:
'    Thisdocumentuses3otherdocuments

2. Utils Namespace

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