What are the performance differences between structs and classes in C#?

Structs are value types and are allocated on the stack, while classes are reference types and are allocated on the heap. This can lead to performance differences, especially in memory allocation and garbage collection.

When should I use a struct instead of a class?

You should use a struct when you need a lightweight object that represents a single value or a small group of related values, and when you want to avoid the overhead of heap allocation.

Are there any downsides to using structs?

Yes, structs can lead to performance issues if they are large or if they are passed around frequently, as they are copied by value. This can increase memory usage and reduce performance.

Can you give an example of when a class would be better than a struct?

A class would be better when you need to manage a complex object with a lot of data or behavior, or when you need to use inheritance, as structs do not support inheritance.
