主题：批量修改文件名应该怎么做

批量导入文件后。我想把被导入的  图片都改为（客户名+id）应该怎么办呢？ 用到哪个事件？ 代码该怎么写呢？   此主题相关图片如下：??.png   有看到这个例子 但是不会应用，还望各位指点一下。   示例五 假定表中有两列，分别是身份证号码和照片，希望向照片列添加文件的时候，能自动根据身份证号码来重命名 此文件，为此可将BeforeAttachFile事件代码设置为： Dim dr As DataRow = e.DataRow If dr.IsNull("身份证号码")  Then     MessageBox.Show("请先输入身份证号码!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)     e.Cancel = True Else     e.FileName = dr("身份证号码") & ".jpg" End If

Dim Cols1() As String = {"productID","ID","color","weight","productNum","productRemarks","ischeck","caseNo","leaderID"}
Dim Cols2() As String = {"productID","订单ID","订单颜色","订单大小","订单数量","订单备注","订单状态","订单号码","客户ID"}
For Each dr1 As DataRow In DataTables("订单详情").Select("[id] Is not Null")
    Dim dr2 As DataRow = DataTables("新订单").AddNew()
    For i As Integer = 0 To Cols1.Length -1
        dr2(Cols2(i)) = dr1(Cols1(i))
    Next
Next
