Question

This is easy in C, how would I do it in VB?
This is what I am trying right now.

Dim a As String = "a"
Dim b As String = "b"
Dim c As String = "c"
Dim d As String = "d"

For Each i in {a, b, c, d}
    i = "blah" & i
End For

This doesn’t work because this is only modifying i and not the underlying variable.

What I really need is a pointer!?

VB’s For Each loop doesn’t support such a construct. That’s a pity but there are better ways anyway. Try to avoid loops in general:

Dim items = {a, b, c, d}.Select(Function (s) "blah" & s)

And in case that’s not valid VB (combining collection initialisers with method calls …) the following does work:

Dim items = (New List(Of String)() From {a, b, c, d}).Select(Function (s) "blah" & s)
