I have a tab delimited text file that I open in Excel.
While it is open in Excel I need to open and read it from my C# application.
I get an access error opening the file with StreamReader or File.Open
The error message says that another application has the file open (which of
course I already knew).
Notepad can open the file while it is open in Excel. Why can't the framework?
I've tried specifying the access as read-only, no luck.
Any suggestions would be appreciated.
