Credit to @Tim as he got here first and gave good start for the answer (give the man an up tick!).

But just to add to it (in C#) . . .

The follow code will provide global scope (Get you the desired info anywhere in your Add-In application).

Microsoft.Office.Interop.Excel.Range stuff =
     Globals.ThisAddIn.Application.Selection as Excel.Range;

Notes:

1. Check that (stuff != null)
2. "ThisAddIn" should be replaced with your Add-In name.
3. Selection returns a value of type dynamic (it is completely ignored by the compiler). As a result (and as far as the compiler is concerned), it has no type until it is cast/assigned to a variable.
