已知"a|b|c", "b|c|d", "d|e|f"，怎么通过代码将这三个合并得到"a|b|c|d|e|f"？

Dim a As String = "a|b|c"
Dim b As String = "b|c|d"
Dim c As String = "d|e|f"
Dim z As String
Dim a1() As String = a.Split("|")
For i As Integer = 0 To a1.Length - 1
If b.Contains(a1(i))=False And c.Contains(a1(i))=False Then
If z = "" Then
z = a1(i)
Else
z += "|" & a1(i)
End If
End If
Next
Dim b1() As String = b.Split("|")
For o As Integer = 0 To b1.Length - 1
If c.Contains(b1(o))=False Then
z += "|" & b1(o)
End If
Next
Output.Show(z & "|" & c)

求更简单更简洁的代码！

Dim a As String = "a|b|c"
Dim b As String = "b|c|d"
Dim c As String = "d|e|f"
Dim ls As new List(of String)
Dim arys() = {a, b, c}
For Each ary As object In arys
    For Each s As String In ary.split("|")
        If ls.Contains(s) = False Then
            ls.add(s)
        End If
    Next
Next
msgbox(String.join("|", ls.ToArray))
