在ASP.NET中跟踪Excel中的修订

我已经设法保持Microsoft Word的跟踪修订属性。它工作得很好。

如何为MS Excel 2007及以上版本做相同的操作?以下是我的word代码(工作正常)，接下来是Excel，我试图执行。

1. :

   Word.Application app = new Word.Application();
   Word.Document tempDoc = app.Documents.Open(path);
   tempDoc.TrackRevisions = true;
   tempDoc.Protect(typ, ref missing, ref password, ref missing, ref missing);
   

Excel:

2. Excel.Application ex_APP = new Excel.Application();
   Workbook wrk = ex_APP.Workbooks.Open(path);
   

无法通过此。当我尝试

wrk.

我没有得到property as trackReviosons

using Excel = Microsoft.Office.Interop.Excel;  

//Gets Excel and gets Activeworkbook and worksheet
Excel.Application oXL;
Excel.Workbook oWB;
Excel.Worksheet oSheet;
oXL = (Excel.Application)Marshal.GetActiveObject("Excel.Application"); 
oXL.Visible = true;
oWB = (Excel.Workbook)oXL.ActiveWorkbook; 
docProps = oWB.CustomDocumentProperties
