Summary

Completed

In this module, you learned about the core functionalities and use cases of C# collections. We covered List<T> for ordered, indexable data, HashSet<T> for managing unique elements, and Dictionary<TKey, TValue> for storing key-value pairs. You also explored common operations like adding, removing, and iterating through items, and scenarios where each collection is most effective, such as dynamic data binding with ObservableCollection<T> or performing set operations with HashSet<T>.

After completing this module, you're now able to:

• Use List<T> to manage ordered sequences of elements with dynamic resizing and indexed access.
• Implement HashSet<T> to handle unique, unordered elements and perform set operations.
• Utilize Dictionary<TKey, TValue> to store and retrieve data using unique key-value pairs.
• Choose the appropriate collection type based on specific application requirements, such as ensuring uniqueness or enabling fast lookups.
