lvw.StopRedraw() \'停止绘制
lvw.Groups.Clear() \'清除原来的分组

lvw.Images.Clear() \'清除原来的图片
lvw.GridLines = True \'显示网格线

c.Width = wds(i) \'指定列宽
Next
For k As Integer = 0 To ins.Length - 1 \'增加行，这里增加的是接收的行
Dim r As WinForm.ListViewRow = lvw.Rows.Add()
If k Mod 2 = 0 Then \'除2为偶数 \'设置交替行背景颜色
r.BackColor = Color.DarkSeaGreen
End If
r("接收文件") = ins(k)
r("发出文件") = outs(k)
Next
For Each vr As WinForm.ListViewRow In lvw.Rows
Dim tx As String = vr.Cells("发出文件").Text
MessageBox.Show(tx)
Next
\'第二个fot语句就会报错？？？？？？？？？？？？？？
For Each cr As WinForm.ListViewRow In lvw.Rows
MessageBox.Show(cr.Cells("接收文件").Text)
Next
lvw.ResumeRedraw() \'恢复绘制

第一个列要这样访问
For Each cr As WinForm.ListViewRow In lvw.Rows
MessageBox.Show(cr.Text)
Next
