Possible to have array of booleans?

Dim b1 As Boolean, b2 As Boolean, b3 As Boolean
Dim obj() As Object = {b1, b2, b3}
dim v As Object
For Each v In obj
v = True
Next

This does not work. Is it possible to have an array of
booleans that can be set in a loop as above? What would
that look like?

Dim bArray(9) As Boolean

For lCnt As Integer = 0 To bArray.Length - 1
bArray(lCnt) = True
Next lCnt

Sub objthing()
Dim B1 As Boolean, B2 As Boolean, B3 As Boolean
Dim obj(2) As boolean
obj(0) = Bn1
obj(1) = Bn2
obj(2) = Bn3
Bn1 = False
For i As Integer = 0 To obj.Length - 1
obj(i) = True
Next
Console.WriteLine(Bn1) 'Bn1 is still False
End Sub

Is there some kind of structure I could place my booleans
into where I could use them in a loop as above? Would an
Arraylist work? Or some kind of pointer structure?

In addition to the other replies: Make sure you read the documentation
on value types, reference types, and boxing.
