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:

Answer 2

The accepted answer points in the right direction, but the correct syntax is:

Excel.Range cell; 
cell.AddComment("My comment");

Answer 3

Excel._Worksheet oSheet =
  (Microsoft.Office.Interop.Excel._Worksheet) excelWorkbook.ActiveSheet;
oSheet.Cells[2, 3].Cells.AddComment("Selam");

Answer 4

Have you tried using VSTO ? You can easily load an Excel document and manipulate it. To add a comment to a cell, load the file, activate the worksheet, then select the cell as a range and set the comment.
