Properties
Documentation Page: HardwareList.Properties.Settings
1. Purpose
This module defines the application settings infrastructure for the HardwareList module within the DataPRO system. Specifically, it provides a strongly-typed, thread-safe singleton accessor (Settings.Default) for reading application-level configuration values stored in the standard .NET configuration system (e.g., app.config or user.config). It serves as the runtime interface to persisted settings but contains no user-defined settings properties itself—only the infrastructure class required to expose them.
2. Public Interface
The module exposes a single internal sealed class with the following public members:
Settings.Default(static property)- Type:
HardwareList.Properties.Settings - Signature:
public static Settings Default { get; } - Behavior: Returns the singleton instance of the
Settingsclass. The instance is created viaApplicationSettingsBase.Synchronized(...), ensuring thread-safe access to settings values. This is the only public entry point to the settings system in this file.
- Type:
Note
: No user-defined settings properties (e.g.,
string SomeSetting { get; set; }) are declared in this file. Their absence indicates that either:
- Settings are defined elsewhere (e.g., in
Settings.settingsdesigner file orapp.config), or- This module is intentionally minimal and relies on external configuration sources.
3. Invariants
- The
defaultInstanceis lazily initialized on first access toSettings.Defaultand remains constant thereafter. - Thread safety is guaranteed via
ApplicationSettingsBase.Synchronized(...), which wraps the instance in aSyncRoot-based synchronization mechanism. - The class is
sealedandinternal, preventing external inheritance or instantiation. - No validation or transformation logic is present in this file; settings values are assumed to be validated/typed by the underlying .NET configuration system at runtime.
4. Dependencies
- Depends on:
System.Configuration(specificallySystem.Configuration.ApplicationSettingsBase)System.Runtime.CompilerServices.CompilerGeneratedAttributeSystem.CodeDom.Compiler.GeneratedCodeAttribute
- Depended on by:
- Other modules in the
HardwareListassembly (e.g., code that reads settings viaSettings.Default.SomeProperty, though no such usage is visible in the provided source). - The .NET configuration system at runtime (via
app.config/user.config), which must contain matching<setting>entries for any properties defined inSettings.settings.
- Other modules in the
5. Gotchas
- Auto-generated file: This file is auto-generated by the Visual Studio Settings Designer (
SettingsSingleFileGenerator). Manual edits will be overwritten on regeneration. - No settings defined here: Despite the class name
Settings, this file contains no property declarations. Any settings used at runtime must be defined in the correspondingSettings.settingsfile (not provided) or inapp.config. - Thread-safety caveat: While
Synchronized()ensures thread-safe access, it does not guarantee atomicity for compound operations (e.g., read-modify-write). - Versioning ambiguity: Assembly version is fixed at
1.0.0.0(withAssemblyFileVersionidentical), which may complicate deployment or rollback if settings schema evolves. - COM visibility disabled:
ComVisible(false)means this module is not exposed to COM clients—intentional for a .NET-only module.
