Visual Basic Console - Integer that would randomly generate every times its used

What i'm basicly looking to do here is create somewhat of a dice that would be rolled everytime I ask it to be used in an equation. For example if I create a d10 and use the following code:

Dim PlayerStr As Integer
PlayerStr = 2
Dim PlayerHit As Integer    
PlayerHit = d10 + PlayerStr

Is there are way for me to use the d10 again later in the code for example for something like this Enemyhit = d10 + enemystr and have the d10 be "rolled" both times? I've tried doing it this way

Module Module1

    Public RNG As New Random
    Public d10 As Integer
    d10 = RNG.next(1, 11)
Sub Main ()
...
End Sub

End Module

But as far as I understand this it would roll the d10 once the program starts and then use that value every time it would be told to use the d10 or am I mistaken?
