[RESOLVED] Adding space every two digits or letters

[stanav]

Just simply loop thru the characters of the string step 2 and build your new string by appending the current 2 chars and a space to a stringbuilder object.
Some thing like this

Dim originalString As String = "your original string here"
Dim sb As New System.Text.StringBuilder()
Dim length As Integer = originalString.Length
If length >= 2 Then
    sb.Append(originalString.Substring(0, 2) & " ")
    For i As Integer = 2 To length - 1 Step 2
          sb.Append(originalString.Substring(i, 2) & " ")
    Next
    If length Mod 2 <> 0 Then
          sb.Append(originalString(length - 1))
    End If
Else
    sb.Append(originalString & " ")
End If
Dim modifiedString As String = sb.ToString

Stanav, thank you very very very much. That one was a lot faster code. Didn't understand it first but now i do and really run fast.

Thanks to both for the help.
