Insert cell comments in excel programmatically

Question

What's the better way to insert cell comments in excel 2007 files programmatically using c# and .net 3.5?

Answer 1

I just did exactly that but with MS Word (using Microsoft.Office.Interop.Word

range.Comments.Add ( range, ref _categoryMessage );

So, I would suggest using Microsoft.Office.Interop.Excel and the similar method. Consider this from MSDN:
