统计表导出时报错：
此主题相关图片如下：运行报错.png
如何修改代码？请指教！谢谢！
Dim dlg As New SaveFileDialog \'定义一个新的SaveFileDialog
dlg.Filter= "Excel文件|*.xls" \'设置筛选器
If dlg.ShowDialog = DialogResult.Ok Then \'如果用户单击了确定按钮
If e.Form.Controls("年级1").value Is Nothing Then
MessageBox.Show("请选择或输入统计年级后再执行此操作","中止操作",MessageBoxButtons.OK,MessageBoxIcon.Exclamation)
Else
Dim xks() As String = {"考号","化","生","政","地"}
Dim nj As String = e.Form.Controls("年级1").text
For Each xk As String In xks
If DataTables.Contains(nj & xk &"考号条码汇总") Then
Tables(nj & xk &"考号条码汇总").SaveExcel(dlg.FileName,nj & xk &"考号条码汇总") \'保存文件
DataTables.Delete(nj & xk &"考号条码汇总") \'删除原文件
End If
Dim book As new XLS.Book(dlg.FileName) \'保存为Excel文件
Dim sheet As XLS.Sheet = book.Sheets(nj & xk &"考号条码汇总") \'保存为Excel文件中的一个工作表
Dim Style As Xls.Style = book.NewStyle \'新建一个样式
Style.WordWrap = XLS.LineStyleEnum.Thin \'单元格内容自动换行
Style.AlignHorz = XLS.AlignHorzEnum.Center \'居中
Style.AlignVert = XLS.AlignVertEnum.Center \'居中
Style.BorderTop = XLS.LineStyleEnum.Thin
Style.BorderBottom = XLS.LineStyleEnum.Thin
Style.BorderLeft = XLS.LineStyleEnum.Thin
Style.BorderRight = XLS.LineStyleEnum.Thin
Style.BorderColorTop = Color.Black
Style.BorderColorBottom = Color.Black
Style.BorderColorLeft = Color.Black
Style.BorderColorRight = Color.Black
For i As Integer = 0 To sheet.Rows.count -1
For n As Integer = 0 To sheet.Cols.count -1
sheet(i,n).Style = Style
Next
Next
Book.Save(dlg.FileName) \'保存文件
Next
End If
e.Form.Controls("Label1").Text = "考号条码汇总已导出并删除!"
End If
Dim xks() As String = {"考号","化","生","政","地"} 只有“考号”存在，"化","生","政","地"不存在时就出现报错，"考号","化","生","政","地"都存在时没问题。
