How can I improve the performance of collections in C#?

How can I improve the performance of collections in C#?

To improve performance, consider using the right collection type, like List<T> for dynamic arrays or Dictionary<TKey, TValue> for key-value pairs.

What are the differences between List<T> and LinkedList<T>?

List<T> provides fast access by index, while LinkedList<T> allows for efficient insertions and deletions.

When should I use HashSet<T>?

Use HashSet<T> when you need a collection of unique elements and require fast lookups.

Are there any performance considerations for using arrays?

Yes, arrays have fixed size and provide fast access, but resizing them can be costly.
