How do C# collections manage memory?

How do C# collections manage memory?

C# collections, like lists and dictionaries, use dynamic memory allocation to manage their elements. They automatically resize as needed.

What happens when a collection grows beyond its initial capacity?

When a collection exceeds its capacity, it allocates a new, larger array, copies the existing elements to the new array, and then frees the old array.

Are there any performance implications of using collections?

Yes, resizing collections can be costly in terms of performance. It's often better to initialize them with a capacity that matches your expected size.

How can I optimize memory usage with collections?

You can optimize memory usage by choosing the right collection type, pre-allocating capacity, and using value types when possible.
