Hi. How do I remove all elements from one collection which exist in another collection without removing duplicates, using LINQ

Please kindly modify the following code so that it works as intended.

Dim stringarray1 As String()
   stringarray1 = {"hello","bye","bye"}

Dim stringarray2 As String()
   stringarray2 = {"hello","hello","bye"}

Dim result1 As String()
   result1 = stringarray1.Except(stringarray2)
   ' outputs nothing, but the desired output is "bye"

Dim result2 As String()
   result2 = stringarray2.Except(stringarray1)
   ' outputs nothing, but the desired output is "hello"
