I dont know if it's the best way of doing this but I don't think there's an equivalent operator.
Dim myString As String =
"Hello" & Environment.NewLine & "there" & Environment.NewLine & "mister"
I think the Environement.NewLine
takes the correct line feed, depending on the OS.
EDIT: I've just read that you want to insert text multiline directly in the code, so there's another possible solution:
You have to use string quotations still, and commas, but here it is
Dim myList as new List(of String) (new String(){
"Hello",
"there",
"mister"
})
Dim result as String
For Each bob as String In myList
result += bob & Environment.NewLine
next
