Unable to iterate through lambda query.

Unable to iterate through lambda query.

Unable to iterate through lambda query.

Supposing the following code, is it possible to incorporate the iterator of the for loop to the lambda expression
Is it a good idea to do it and how? The what I want to do is not to use the for loop statement but do the work of iteration of the loop inside the lambda query.
Thank you so much in advanced.

CODE --> Vb.net

Public Sub UCheck(ByVal n As Byte)

UsrCheckerGates = PcCheckerGates

UsrCheckerGates(1).ReversePos = 100

Dim PG As IEnumerable(Of GatesPositions)

PG = PcCheckerGates.Where(Function(x) x.pos > 50)

Dim uany As Boolean

For us As Byte = 1 To 3

Dim f = us

uany = PG.Any(Function(x) UsrCheckerGates.Any(Function(u) u.ReversePos = x.pos - f * 50))


End Sub 

However, I tried the following code, but I can't find a way to access the .value property through iteration inside the lamdba expression
Dim frst = PG.First(Function(x) UsrCheckerGates.Any(Function(u) u.ReversePos = WHAT?
Any suggestions please? Any help will be much appreciated.

CODE --> vb.net

Dim test3 = PG.Select(Function(x) New With {
                         .Position = x.pos,
                         .Dice = 50,
                         .multiple = Multiples.Select(Function(q) New With {
                         .value = x.pos - (q * 50)})})
