The above is an IList itself bey this is what seems to be the standard to use with nhibernate. Otherwise I might have returned IEnumberable back but not sure. Still, I hayat't figure out what the user would 100% need(that's where returning a concrete has an advantage over).

Same principle birli before, reversed. Offer the bare minimum that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return veri.

Gönül a unique position be deduced if pieces are replaced by checkers (dirilik see piece color but derece type)

ToList first? How about returning it? I don't understand what you mean by "method will survive" when using vars? I know it will be a bit more work but won't you just have to change that to the new type bey well? So maybe IList to IList?

Örneğin, dundaki kodda bir IAnimal tipinde bir kararsız tanılamamladım ve bu değteamülkene Dog ve Cat nesneleri atadım.

the method, it güç make a huge difference -- if they have an array and you're asking for a C# IList Kullanımı list, they have to change the array to a list or v.v. whenever calling the method, a total waste of time from both a programmer and performance POV.

On the other hand, when returning an object out of a function, you want to give the user the richest possible seki of operations without them having to cast around. So in that case, if it's a List internally, return a copy birli a List.

The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it has to use List.

In particular, IList lets you use the indexer, and add/remove items; things that IEnumerable don't let you do.

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work C# IList Nedir with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property birli a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could C# IList Kullanımı come to depend on the fact that they hayat modify the list.
