This code-access permission controls the ability for code to allow users to access files and folders through the System.Windows.Forms.OpenFileDialog and the System.Windows.Forms.SaveFileDialog classes. These UI components are useful for providing restricted access to files and folders, without the need to grant permissions with FileIOPermission. The type of file dialog to which access is granted by a FileDialogPermission object is specified at construction using members of the FileDialogPermissionAccess enumeration. To retrieve or modify the file dialog access represented by a FileDialogPermission object, use its Access property.
