C＃和Excel高级filter

我试图从一个工作簿中过滤数据到另一个obne，但我得到一个unpsecifiedexception。

我无法find许多使用c＃在excel中进行过滤的例子，我不知道我的错误在哪里。

这是我的代码：

public void excel() { Excel.Application xlApp; Excel.Workbook xlWorkBookImport; Excel.Workbook xlWorkBookOriginal; Excel.Worksheet xlWorkSheetImport; Excel.Worksheet xlWorkSheetOriginal; xlApp = new Excel.ApplicationClass(); xlWorkBookImport = xlApp.Workbooks.Open("c:/open.xls"); xlWorkBookOriginal = xlApp.Workbooks.Open("c:/open1.xls"); xlWorkBookOriginal.Activate(); xlWorkSheetOriginal = (Excel.Worksheet)xlWorkBookOriginal.Worksheets.get_Item(1); xlWorkSheetOriginal.get_Range("1:7").Delete(); xlWorkBookImport.Activate(); xlWorkSheetImport = (Excel.Worksheet)xlWorkBookImport.Worksheets.get_Item(1); xlWorkSheetOriginal.Cells.AdvancedFilter(Excel.XlFilterAction.xlFilterCopy, Type.Missing, CopyToRange: "a1:a6", Unique: true); xlApp.Visible = true; } 

任何人都可以帮我解决scheme？
