SaveFileDialog Component Overview (Windows Forms)
Working with the SaveFileDialog Component
Use it as a simple solution for enabling users to save files instead of configuring your own dialog box. By relying on standard Windows dialog boxes, the basic functionality of applications you create is immediately familiar to users. Be aware, however, that when using the SaveFileDialog component, you must write your own file-saving logic.
When it is added to a form, the SaveFileDialog component appears in the tray at the bottom of the Windows Forms Designer.
