How to directly get the TResult of a Func of including lambda expression?

[WomanPro]

I would like to ask something please.
Supposing the following expression Dim ExistsPosValue1 As Func(Of GatesPositions, Boolean) = Function(p) p.pos = 3 how can I get with only a statement the returning value (true - false). I can do it with the following but I would like something directly than that? Any explanations please? Thank you so much in advanced. Any help will be much appreciated.

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Chck()
End Sub

Public Sub CheckFuncOf(ByVal ExistsPosValue1 As Func(Of GatesPositions, Boolean), ByVal GtPos As GatesPositions?)

Dim Flg As Boolean

If ExistsPosValue1.Invoke(GtPos) Then

Flg = True

End If

End Sub

Public Sub Chck()

Dim ExistsPosValue1 As Func(Of GatesPositions, Boolean) = Function(p) p.pos = 3

Dim GtPos As GatesPositions? = PcCheckerGates.First(Function(x) x.pos = 3)

CheckFuncOf(ExistsPosValue1, GtPos)

End Sub
