I know there başmaklık been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.

What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?

Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, hamiş add or remove. Accepting an interface as a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.

Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does not.

The Liskov Substitution Principle (simplified) states that a derived type should be able to be used in place of a base type, with no additional preconditions or postconditions.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they can't add or remove items from your object, they sevimli only act against the objects. If you need to expose a collection outside of a class, but don't want to let the caller change the collection, this is one way of doing it.
