Code Structure and Design Patterns

Overview

The project uses a modular approach, with each feature encapsulated in a dedicated folder. This promotes maintainability and reduces complexity by separating concerns.

Design Patterns

Singleton

  • Purpose: Ensures only one instance of a class exists and provides a global point of access to it.

  • Implementation: The Config class serves as a Singleton, responsible for managing configuration data.

  • Example: 

    public class Config 
          {
              private static Config instance;
          
              private Config() { }
          
              public static Config Instance 
              {
                  get 
                  {
                      if (instance == null) 
                      {
                          instance = new Config();
                      }
                      return instance;
                  }
              }
          
              // ...
          }

  • Source: Config.cs

Dependency Injection

  • Purpose: Allows dependencies to be injected into classes, promoting loose coupling and testability.
  • Implementation: The project leverages constructor injection for passing dependencies.
  • Example: 
    public class MyClass
          {
              private readonly IMyDependency _dependency;
          
              public MyClass(IMyDependency dependency)
              {
                  _dependency = dependency;
              }
          }
  • Source: Throughout the project, dependencies are passed via constructor injection.

MVC (Model-View-Controller)

  • Purpose: Separates application logic, user interface, and data into distinct components.
  • Implementation: The project structure reflects the MVC pattern:
    • Models: Represent data structures and business logic (Data folder).
    • Views: Provide the user interface (UI folder).
    • Controllers: Handle user input, interact with models, and update views (Controllers folder).

Folder Structure

  • Data: Contains data models and logic.
  • UI: Provides the user interface.
  • Controllers: Handles user input and interactions.
  • Core: Houses core functionalities and utilities.
  • Tests: Contains unit and integration tests.

Best Practices

  • Code Style: Follows standard C# coding conventions.
  • Naming Conventions: Uses clear and descriptive names for classes, methods, and variables.
  • Error Handling: Implements robust error handling mechanisms.
  • Logging: Provides logging for debugging and monitoring.
  • Testing: Extensive unit and integration tests ensure code quality.
