Summary
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.
