How do different C# collections compare in terms of performance?

How do different C# collections compare in terms of performance?

The performance of C# collections varies based on their implementation. For example, List<T> is generally faster for indexed access, while Dictionary<TKey, TValue> excels in lookups.

What about memory usage? Are there significant differences?

Yes, memory usage can differ significantly. Arrays are more memory-efficient than Lists, but Lists offer more flexibility. Dictionaries use more memory due to their internal structure.

Can you give me a specific example comparing List and LinkedList?

Certainly! List<T> provides O(1) access time for elements, while LinkedList<T> has O(n) for access but O(1) for insertions and deletions at both ends.

Which collection would you recommend for a large dataset?

For large datasets, I recommend using List<T> for its performance in accessing elements, unless you need frequent insertions and deletions, in which case LinkedList<T> might be better.
