Spaces  in the original post could refer to whitespace  and no answer yet shows how to remove ALL whitespace from a string  For that regular expressions are the most flexible approach I ve found   Below is a console application where you can see the difference between replacing just spaces or all whitespace   You can find more about  NET regular expressions at http   msdn microsoft com en-us library hs600312 aspx and http   msdn microsoft com en-us library az24scfc aspx  Imports System Text RegularExpressions Module TestRegExp     Sub Main             Use to match all whitespace  note the lowercase s matters          Dim regWhitespace As New Regex   s              Use to match space characters only         Dim regSpace As New Regex               Dim testString As String    First Line    vbCrLf              Second line followed by 2 tabs    vbTab   vbTab              End of tabs           Console WriteLine  Test string             Console WriteLine testString           Console WriteLine  Replace all whitespace               This prints the string on one line with no spacing at all         Console WriteLine regWhitespace Replace testString  String Empty            Console WriteLine  Replace all spaces               This removes spaces  but retains the tabs and new lines         Console WriteLine regSpace Replace testString  String Empty            Console WriteLine  Press any key to finish           Console ReadKey       End Sub End Module

2015  Newer LINQ  amp  lambda    As this is an old Q  and Answer   just thought to update it with newer 2015 methods  The original  space  can refer to non-space whitespace  ie  tab  newline  paragraph separator  line feed  carriage return  etc  etc   Also  Trim   only remove the spaces from the front back of the string  it does not remove spaces inside the string  eg    Leading and Trailing Spaces   will become  Leading and Trailing Spaces   but the spaces inside are still present      Function RemoveWhitespace fullString As String  As String     Return New String fullString Where Function x  Not Char IsWhiteSpace x   ToArray    End Function   This will remove ALL  white -space  leading  trailing and within the string

You can also use a small function that will loop through and remove any spaces   This is very clean and simple   Public Shared Function RemoveXtraSpaces strVal As String  As String      Dim iCount As Integer   1      Dim sTempstrVal As String       sTempstrVal            For iCount   1 To Len strVal          sTempstrVal   sTempstrVal   Mid strVal  iCount  1  Trim      Next       RemoveXtraSpaces   sTempstrVal       Return RemoveXtraSpaces  End Function
