如何合并并获得2个数据表之间的差异

Question

我们创建了一个合并2个数据表的函数。

这是代码

    Public Shared Function CompareTwoDataTable(ByVal dt1 As DataTable, ByVal dt2 As DataTable) As DataTable
    dt1.Merge(dt2)
    Dim d3 As DataTable = dt2.GetChanges()
    Return d3
End Function

我想知道代码是不正确还是什么，我的观点是我想确定这两个表之间的区别并获得它们的区别。

提前致谢

对于那些查看此内容的人来说，这是我已经提出的代码

我已经创建了一个使用其ID比较2数据表的函数

Public Shared Function CompareTwoDataTable(ByVal dt1 As DataTable, ByVal dt2 As DataTable) As DataTable Dim rows_to_remove As New List(Of DataRow)() For Each row1 As DataRow In dt1.Rows For Each row2 As DataRow In dt2.Rows If row1("ID").ToString() = row2("ID").ToString() Then rows_to_remove.Add(row1) End If Next Next For Each row As DataRow In rows_to_remove dt1.Rows.Remove(row) dt1.AcceptChanges() Next Dim d3 As DataTable = dt1 Return d3 End Function
