主题：[求助]如何从两个表的指定列中 合并取得不重复的值？

参考代码

Dim ls1 As List(Of String) = DataTables("表A").GetValues("第一列")
Dim ls2 As List(Of String) = DataTables("表B").GetValues("第一列")
For Each s As String In ls2
    If ls1.Contains(s) = False Then
        ls1.add(s)
    End If
Next

msgbox(String.Join(",", ls1.ToArray))
