c#和Excel高级过滤器

我试图将数据从一个工作簿过滤到另一个工作簿，但我得到一个未指定的异常。

我找不到很多使用c#在excel中进行高级过滤的例子，我不知道我的错误到底在哪里。

下面是我的代码:

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;
    }
谁能给我一个解决方案?

c#和Excel高级过滤器

最后我自己弄明白了:

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(); 
// added code
Excel.Range range = xlWorkSheetOriginal.get_Range("a1:v53");  
//  
xlWorkBookImport.Activate(); 
xlWorkSheetImport = (Excel.Worksheet)xlWorkBookImport.Worksheets.get_Item(1);
// added code
xlWorkSheetImport.Activate();
Excel.Range target = xlWorkSheetImport.get_Range("a1:f1"); 
//
// modified code            
xlWorkSheetOriginal.Cells.AdvancedFilter(Action : Excel.XlFilterAction.xlFilterCopy, 
CriteriaRange: Type.Missing, CopyToRange: target, Unique: false);
//          
xlApp.Visible = true;     
}
