Hi experts,
    I need to get  a  
The documentNumber is a string type variable . The typical value has actual number and the revision at the end after _ (Underscore)
  A-BB-C-DD_1
   A-BB-C-DD_10

 Also it has to consider the possibility of a wrongly named  document
    WrongPattern_StillNeedtoPick_1

    From the above 3 examples , I need to get the result as follows  ( ActualName , Rev are variables of string type)

      ActualName                                               Rev
       A-BB-C-DD                                                 1
      A-BB-C-DD                                                  10
     WrongPattern_StillNeedtoPick                 1

      I have some idea to do this with  split function . Still looking for comprehend code

Hi Pawan,
     Wrong pattern can have _ anywhere  potentially . But  the the text after  final _  should be taken as the Rev and rest should be taken as Document name ( as in examples of my original post)

Please try..

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        Dim str As String = "A-BB-C-DD_10"
        Dim Output As String = ""       

        If str.IndexOf("A-BB-C-DD_") <> -1 Then
            Output = str.Substring(str.IndexOf("A-BB-C-DD_") + "A-BB-C-DD_".Length)
        Else
            Output = str.Substring(str.LastIndexOf("_") + 1)
        End If

    End Sub

Open in new window


Hope it helps !!

I think this will be even better..

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        Dim str As String = "A-BB-C-DD_10"
        Dim Output As String = ""       
      
       Output = str.Substring(str.LastIndexOf("_") + 1)       

    End Sub

Open in new window
