大神帮忙看下，代码出错了，怎么改
Select Case e.DataCol.Name
Case "上次欠款","上货金额","退货金额","还款金额","欠款金额"
Dim dr As DataRow
Dim drs As List(of DataRow)
dr = e.DataTable.Find("[_SortKey] < " & e.DataRow("_SortKey"), "[_SortKey] Desc")
If dr Is Nothing Then
e.DataRow("欠款余额") = e.DataRow("上次欠款") + e.DataRow("上货金额")-e.DataRow("退货金额")- e.DataRow("还款金额")
dr = e.DataRow
End If
drs = e.DataTable.Select("[_SortKey] >= " & dr("_SortKey"), "[_SortKey]")
For i As Integer = 1 To drs.Count - 1
drs(i)("欠款余额") = drs(i-1)("上次欠款") + drs(i)("上货金额") - drs(i)("退货金额") - drs(i)("还款金额")
Next
End Select
