Question

is there a way i can do like this in vb.net

dim idx = -1
dim a = array(idx = idx + 1)
dim b = array(idx = idx + 1)
dim c = array(idx = idx + 1)
dim d = array(idx = idx + 1)

what i want is that idx keeps incrementing after each line, without incrementing it on a seperate line.

Thank you

I don’t think VB.Net has anything like that, but you can make an extension to get close to it:

Imports System.Runtime.CompilerServices

Public Module Module1

  <Extension()> _
  Public Function UpIndex(ByRef value As Integer) As Integer
    value += 1
    return value
  End Function

End Module

Note the use of ByRef in the arguments.

Then your call would look like this:

Dim a = array(idx.UpIndex)
Dim b = array(idx.UpIndex)
