    ' Alternatively:
    '   Dim cmpi As CompareInfo = New CultureInfo("en-US").CompareInfo

    ' Create sort keys for lowercase and uppercase "abc", the en-US culture, and 
    ' ignore case. 
        Dim sk1LowerIgnCase As SortKey = cmpi.GetSortKey(lowerABC, CompareOptions.IgnoreCase)
        Dim sk2UpperIgnCase As SortKey = cmpi.GetSortKey(upperABC, CompareOptions.IgnoreCase)

    ' use case.

        Display(result, "SortKey, Use case", lowerABC, upperABC)
    End Sub
    
    ' Display the results of a comparison.
