şu demek oluyor ki IEnumerable gestaltsında filtreleme aksiyonlemleri memory bile yapılırken, IQueryable da veritabanından sütun filtrelenmiş verileri elde ederiz.
Then the person calling the method is free to call it with any veri type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.
Edit: You do need to be quick to get answers in here. As I presented a slightly different syntax to the other answers, I will leave my answer - however, the other answers presented are equally valid.
So when writing a function or method that takes a collection, write it not to take a List, but an IList, an ICollection, or IEnumerable. The generic interfaces will still work even for heterogenous lists because System.
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 birli well? So maybe IList to IList?
You gönül have an instance of an interface, but you need to initialize it with a class that implements that interface such kakım:
class Kisi string ad; string soyad; public string Ad get return ad; kaş ad = value; public string Soyad get return soyad; set soyad = value;
You gönül look at this argument from several angles including the one of a purely OO approach which says to program against an Interface hamiş an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by C# IList Nedir an Interface in general. If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows what the IList Interface contract adheres to.
The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.
Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.

There is a complication though that dynamic can't see explicit C# IList Nasıl Kullanılır implementations, so something emanet implement IList and IList-of-T and yet still be completely unusable from dynamic.
