OpenFileDialog , SaveFileDialog
OpenFileDialog and SaveFileDialog have a number of common properties, among which
are the following:
DefaultExt: sets the file extension, which is added by default, if the user entered a file
name without an extension
AddExtension: if set to true, adds an extension to the file name when it is empty. The
extension is taken from the DefaultExt or Filter property
CheckFileExists: if it is true, it checks the existence of a file with the specified name
CheckPathExists: if it is true, it checks the existence of the path to the file with the
specified name
FileName: returns the full name of the file selected in the dialog box

buttons: button1 and button2 to the form. Also, we drag the
OpenFileDialog and SaveFileDialog components from the toolbar.
After the addition, they will appear at the bottom of the form
designer. As a result, the form will look something like this:
