If you have the LINQ namespace at your disposal, then you can use the Except extension method for this purpose. Here's an example:

Imports System.Linq

Module Module1

    Sub Main()
        Dim firstHashSet As New HashSet(Of String)
        Dim secondHashSet As New HashSet(Of String)

        firstHashSet.Add("one")
        firstHashSet.Add("two")

        secondHashSet.Add("three")
        secondHashSet.Add("one")

        Dim removedFromSecond = firstHashSet.Except(secondHashSet)
        Dim addedToSecond = secondHashSet.Except(firstHashSet)

        For Each item In removedFromSecond 
            Console.WriteLine(item)
        Next

        Console.WriteLine()

        For Each item In addedToSecond 
            Console.WriteLine(item)
        Next

        Console.ReadKey()
    End Sub

End Module
