What are collection interfaces in C#?
Collection interfaces in C# are used to define standard methods for collections, like IList, ICollection, and IEnumerable.
Can you explain the difference between IList and ICollection?
Sure! IList allows indexed access to elements, while ICollection provides basic collection functionalities without indexing.
When should I use IEnumerable instead of IList?
Use IEnumerable when you only need to iterate over a collection without modifying it, as it's more lightweight.
Are there any performance considerations when using these interfaces?
Yes, performance can vary based on the implementation. For example, List<T> is faster for indexed access than LinkedList<T>.
