List two have 3 values 1810458073, 1810458074 and 1810458074
There is a duplicate (1810458074) in list two which is what I want to find.
I understand this as searching duplicates in a single list as the list contains 1810458074 2 times.
Dim list1 = New List(Of Integer) From {1810458073, 1810458074, 1810458074}
For x = LBound(list1) to UBound(list1) - 1
For y = x + 1 to UBound(list1)
If list1(x) = list1(x) then
End If
Next
