Movie Library Management System

Overview

This is a WPF-based application developed using .NET 9.0. It allows users to manage a movie library with features like adding, sorting, borrowing, and returning movies.

Features

• Add new movies to a library
• Search by title or ID
• Sort by title (Bubble Sort)
• Sort by year (Merge Sort)
• Borrow/Return movies
• xUnit tests with 100% coverage

Technologies Used

• .NET 9.0 SDK (WPF)
• xUnit for unit testing
• C# with LinkedList, Dictionary, Queue data structures

Getting Started

git clone Movie-Application-APA1
cd Movie-Application-APA1
dotnet restore
dotnet build
dotnet run
dotnet test

Project Structure

• APA1.csproj: Main WPF application
• MOVIE_APPLICATION_APA1.Tests.csproj: xUnit test project
• MovieLibrary.cs: Backend logic
• MainWindow.xaml: Frontend UI
• README.md, TestPlan.md: Documentation

How to Use

When you launch the application (dotnet run from the APA1 project), the following features are available in the WPF window:

Searching

• Search by Title: Type part of a movie title in the first textbox and click "Search Title" to see all matches.
• Search by ID: Enter a movie ID (e.g., M001) in the second textbox and click "Search ID" to find a specific movie.

Adding Movies

• Click "Add Movie" to insert a new movie with default details.
• New movies get auto-generated IDs like M001, M002, etc.

Sorting

• Use "Sort by Title" to alphabetically order the movie list.
• Use "Sort by Year" to arrange movies by their release year.

Borrowing & Returning

• Select a movie row from the list.
• Click "Borrow Movie" to mark it as unavailable.
• Click "Return Movie" to make it available again.

How It Works

• MovieLibrary.cs manages the data using:
  • LinkedList<Movie> for storing movies
  • Dictionary<string, Movie> for fast ID lookup
  • Queue<string> to simulate a borrow waitlist
• Sorting is done manually with:
  • Bubble Sort (Title)
  • Merge Sort (Year)
• UI is written in MainWindow.xaml using WPF components like DataGrid, TextBox, and Button.
