I would save these types of elements in a list, and then apply every cycle for them, assuming that they are all of the same type (or at least the base type). Assuming you are using label controls, this would be a solution. Note that I changed .fontColor to .ForeColor so that this example works with the Label class:
Dim lblList as new List(of Label) ({lblA, lblB, lblC}) lblList.ForEach(sub(x) x.Fore Color = color.red)
Since you posted your solution, you can still do the following to avoid iterating through the array you made (which is why I am doing this as a list), not taking into account the size of the array or something else:
lblList.ForEach(Sub(x) With x .BackColor = Color.Black .Dock = DockStyle.Top .TextAlign = ContentAlignment.MiddleCenter End With End Sub)
