Question

I’m having a problem when using variables in object names.

I have a Public class which is called “Tank”
In that class, there is a public property called “direction” of an integer type.

I keep getting the error:
“Tank is a type and cannot be used as an expression”
What I’m doing wrong here ?

Public Class mainroutines()

' Create Instances of tank  

Private Tank1 As New Tank()
Private Tank2 As New Tank()

'Loop trough objects and set the property value

dim i as integer
For i = 1 to 2
Tank(i).direction = 1
next i

End class

Answer 1

Well, Tank(i) is not equivalent to Tank1. You would need to make a list of tanks, add your instances to it, and access them that way.

Public Class mainroutines() 

' Create Instances of tank '  

Dim allTanks As List(Of Tank) = New List(Of Tank) 
allTanks.Add(New Tank())
allTanks.Add(New Tank())

'Loop through objects and set the property value '

dim i as integer 
For i = 1 to 2 
allTanks(i).direction = 1 
next i
