How can I optimize collections in C# for better performance?

How can I optimize collections in C# for better performance?

You can optimize collections in C# by choosing the right collection type, minimizing resizing, and using efficient algorithms.

What are the differences between List<T> and Array in terms of performance?

List<T> offers dynamic resizing and more flexibility, while Array has fixed size and can be faster for certain operations.

Are there specific scenarios where I should use HashSet instead of List?

Yes, use HashSet when you need fast lookups and uniqueness, as it provides O(1) average time complexity for these operations.

How can I measure the performance of my collections?

You can use the Stopwatch class to measure execution time and analyze performance using profiling tools.
