序号列整数型，以下代码报错什么问题？
Select Case e.DataCol.Name
Case "表名称"
Dim fn As winform.form = Forms("审核流程设置")
If fn.Opened Then
Dim tr As WinForm.TreeView = fn.Controls("TreeView1")
For Each sd As WinForm.TreeNode In tr.AllNodes
If sd.Text = e.OldValue Then
sd.Text=e.NewValue
End If
Next
End If
Dim drs As List(Of DataRow)
drs = DataTables("审核流程管理").Select("[表名称] = '" & e.OldValue & "'")
For Each dr As DataRow In drs
dr("表名称") = e.NewValue
dr.Save
Next
Case "序号"
Dim fn As winform.form= Forms("审核流程设置")
If fn.Opened Then
Dim tr As WinForm.TreeView = fn.Controls("TreeView1")
For Each sd As WinForm.TreeNode In tr.AllNodes
If sd.Text = e.OldValue AndAlso sd.parentnode.Text= e.DataRow("表名称") Then
sd.Text = e.NewValue
End If
Next
End If
Dim drs As List(Of DataRow)
drs = DataTables("审核流程管理").Select("[序号] = '" & e.OldValue & "'")
For Each dr As DataRow In drs
dr("序号") = e.NewValue
dr.Save
Next
End Select
