This enumeration is used in conjunction with the FileDialogPermission class to specify the type of file dialog access a FileDialogPermission object represents. Open represents the ability to call the System.Windows.Forms.OpenFileDialog.OpenFile( ) method, and Save represents the ability to call the System.Windows.Forms.SaveFileDialog.OpenFile( ) method. The OpenSave value represents the combined permissions of both the Open and Save values; None represents no access.
