The main difference between ArrayList and List in C# is that ArrayList can store any type of object without type-safety, while List<T> is a generic collection that enforces type-safety and allows you to store only a specific type which reduce the risk of runtime errors.
- In C#, List<T> is generally preferred over ArrayList for better performance, readability, and compile-time type checking.
- You can use ArrayList when you need a dynamically resizable collection and need to store elements of different types.
