How to create an array of objects Visual Basic

Question

Is it possible to create an array of objects in visual basic?

I'm making a battle system and whenever the battle begins, i wanna be able to randomly select a Monster object from an array.

If it is possible, could somebody show me how to store Public Spider as New Monster(50, 20, 5) into an array?

Thank you.

Monster Class:

Public Class Monster

  Private hp As Integer
  Private xp As Integer
  Private dmg As Integer

  Sub New(ByVal hitpoints As Integer, ByVal exp As Integer, ByVal damage As Integer)
    hp = hitpoints
    xp = exp
    dmg = damage
  End Sub

End Class

Form Class:

Imports Monster
Public Class Form

  Public Spider As New Monster(50, 20, 5)

End Class

A List(Of T) would work great for that.

Private Monsters As New List(Of Monster)
'later add them into this collection
Monsters.Add(New Monster(50, 20, 5))

You could use one of the Collections like List(of Monster) to hold it if you don't have a set and knowable number of class instances to store.

Dim Monsters As List(of Monster) = New List(of Monster)
Monsters.Add(New Monster(10, 50, 30))

Of course, ArrayList is better, but your question is useful too.

  Dim MonsterArr() As Monster = New MonsterArr(1000) {}

or

  Dim MonsterArr() As Monster = New MonsterArr(1000) {0,0,0}

or

  Dim MonsterArr() As Object = New Object(1000) {}
