Excel: can only open file if using absolute path, why?

Question

I have some trouble to understande why I´m getting an exception. I have something like this:

string path = \"file.xls\";
if (File.Exists(path))
{
  Excel.App         


        

Answer 1

i think it is because xlApp.Workbooks.Open function only knows the absolute path,not likes File.Exists function
