[RESOLVED] Lambda Expression Confusion

[BlindSniper]

Hi all,
I've been wondering about lambda expressions for a while now.
Consider the following code

Sub Main()
        Dim I As Integer
        SomeUselessSub(Sub()
                           Dim K As Integer = I
                       End Sub)
 
        SomeUselessSub(New Action(AddressOf DoSomething))
    End Sub
    Sub DoSomething()
 
    End Sub
 
    Sub SomeUselessSub(ByVal D As [Delegate])
 
    End Sub

Both

        SomeUselessSub(Sub()
                           Dim K As Integer = I
                       End Sub)

And

 SomeUselessSub(New Action(AddressOf DoSomething))

Are valid calls to SomeUselessSub.
But in the lambda expression I have access to all Sub Main's variables. Is it safe to use them ?
