Question

我有一个DataRow。有没有办法将其转换为arraylist？我需要将它转换为arraylist因为我想将它传递给一个比较两个数组的函数，如果它们不相同则返回false。

foo(datarow, arraylist)


Public Function foo(ByVal arr1 as Arraylist, ByVal arr2 as ArrayList) as Boolean

    Compare and return false if they are not the same

End Function

那么，我如何将datarow转换为arraylist以便我可以将它传递给该函数。

我同意你应该只在必要时转换为ArrayList，但你当然可以。

    Dim al As New ArrayList
    Dim dt As New DataTable

    dt.Columns.Add("f")
    dt.Columns.Add("n")

    Dim dr As DataRow
    dr = dt.NewRow
    dr.Item(0) = "First"
    dr.Item(1) = "Name"
    dt.Rows.Add(dr)

    For Each row As DataRow In dt.Rows

        For Each column As DataColumn In dt.Columns

            al.Add(row.Item(column.ColumnName))

        Next

        MessageBox.Show(al.Item(0).ToString & " " & al.Item(1).ToString)

    Next

是否可以将DataRow转换为arraylist？
