What are the performance differences between arrays and lists in C#?

Arrays in C# are fixed in size and provide faster access times, while lists are more flexible but can be slower due to dynamic resizing.

Can you explain why arrays are faster?

Arrays have a contiguous memory allocation, which allows for quicker access and better cache performance compared to lists.

Are there any scenarios where I should prefer lists over arrays?

Yes, if you need to frequently add or remove items, lists are more suitable due to their dynamic nature.

What about memory usage between the two?

Arrays generally use less memory since they don't have the overhead of additional features that lists provide.

Can you provide a code example comparing both?

Sure! Here's a simple example:

int[] array = new int[5];
List<int> list = new List<int>();

This shows how to declare both in C#.
