How to Save/Overwrite existing Excel file with Excel Interop - C#

Question

Is there a way to save changes to an excel spreadsheet through the excel interop (in this case I am adding a worksheet to it) without having it prompt the user if they want

Answer 1

Basically, all you need is ExcelApp.DisplayAlerts = False - Here's how I do it, though:

ExcelApp.DisplayAlerts = False
ExcelWorkbook.Close(SaveChanges:=True, Filename:=CurDir & FileToSave)

Hope this helps
