Bey mentioned by Mr. Copsey, this has the benefit of providing decoupling from the implementation, but I'm of the contention that a clear definition of the smallest subset of interface functionality as possible (i.
If you maksat to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.
So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.
IEqualityComparer kullanarak, özel gereksinimlere isabetli veri el işi stratejileri vüruttirebilir ve yürütüm genelinde tutarlılık esenlayabilirsiniz.
The expression hayat simply be a constant expression of the object itself or a more complex tree of a composed seki of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression
So if you working with only in-memory veri collection IEnumerable is a good choice but if you want to query data collection which is connected with database `IQueryable is a better choice birli it reduces network traffic and uses the power of SQL language.
Not: Generic sıfır sınıflar sinein IEnumerable kullanmaında boxing/unboxing anlayışlemleri verimliliği düşüreceği bağırsakin yeni oluşturacağınız projelerinizde generic sınıflar dâhilin olan IEnumerable
IEnumerable gives you the way to C# IEnumerable Nerelerde Kullanılıyor implement your own logic of storing C# IEnumerable Nasıl Kullanılır and iterating over object collection
So you have a common IEnumerator-implementing class for all ten, and each collection just katışıksız to implement IEnumerable using that enumerating C# IEnumerable Nedir class. It's about separation of concerns, treating holding data and enumerating data bey separate operations.
Using the concept of iterators you kişi achieve major improvement in algorithm quality, both in terms of speed and memory usage.
Here is a very good article that details the differences between statement lambdas and expression lambdas and discusses the concepts of expression tress in greater depth: Revisiting C# delegates, expression trees, and lambda statements vs. lambda expressions.."
Generally, don't worry about what's actually in the IEnumerables, birli it will be completely different from your actual code. Only worry about the actual output when you iterate over it :)
IEnumerator kullanarak, koleksiyonun tamamını belleğe yüklemeden, sadece vacip elemanları C# IEnumerable Nasıl Kullanılır işler ve bu sayede belleğin aktif kullanılmasını sağlamlar.
When declaring a method’s parameter types, you should specify the weakest type possible, preferring interfaces over base classes. For example, if you are writing a method that manipulates a collection of items, it would be best to declare the method’s parameter by using an interface such birli IEnumerable rather C# IEnumerable Nerelerde Kullanılıyor than using a strong veri type such birli List or even a stronger interface type such bey ICollection or IList:
