Microsoft.Office.Interop.Excel with "bad value" as default parameters

Question

I am trying to use Microsoft.Office.Interop.Excel. It seems to load normally, but when I try to use it, all the default options do not work. Here is a screenshot that shows all those bad values

Whenever I try to omit them, the compiler tells me that a function requires more than one parameter.

This function is open as in:

   Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
   Workbook wb = excel.Workbooks.Open("ss.xlsx");

How can I use the default value for these 14 parameters?

EDIT I ​​am using C # 3.5 (2008) with Office 2010
