遇到个比较麻烦的问题，
代码是
If e.DataCol.Name = "派送标记" AndAlso e.DataRow ("派送标记") = "1" Then
Dim nma() As String = { "日期","项目名称","申请号","客户站点","客户申请人及电话","客户实物交接人及电话","中兴办事处确认人","设备类型*","坏件名称*" ,"派送件条码*", "客户申请时间","确认时间","到达时间","执行人","实物交接人及电话","随机编号" ,"指令类别*" } 'A表数据来源列
Dim nmb() As String = { "日期","项目名称","派送_派送申请号","客户站点","派送_派送申请人及电话","派送_派送交接人及电话","派送_派送中兴确认人及电话","设备_派送设备类型","设备_派送设备名称","设备_派送设备条码","派送_派送申请时间","派送_派送指令下达时间","派送_派送实际服务到达时间","派送_派送执行人及电话","派送_派送实物交接人及电话","随机编号" ,"指令类别" } 'B表数据接收列
Dim dr As DataRow = DataTables("系统台账").AddNew
For i As Integer = 0 To nma.Length - 1
dr(nmb(i)) = e.DataRow(nma(i))
Next
End If
