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

To improve dictionary performance in C#, consider using the right type of dictionary, optimizing the initial capacity, and minimizing collisions.

What types of dictionaries are available in C#?

C# offers several dictionary types, including Dictionary<TKey, TValue>, SortedDictionary<TKey, TValue>, and ConcurrentDictionary<TKey, TValue>.

How does the initial capacity affect performance?

Setting an appropriate initial capacity reduces the need for resizing, which can be costly in terms of performance.

What are collisions and how can I minimize them?

Collisions occur when multiple keys hash to the same index. You can minimize them by choosing a good hash function and ensuring a uniform distribution of keys.
