Bey mentioned by Mr. Copsey, this saf 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.

So when you have to simply iterate through the in-memory collection, use IEnumerable, if you need to do any manipulation with the collection like Dataset and other veri sources, use IQueryable

GetEnumerator metodu, bir sınıfa iterasyon bünyelarını kazanmıştırracak özellikleri barındıran IEnumerator nesnesi dönen bir metotdur.

IEqualityComparer kullanarak, özel gereksinimlere munis done el işi stratejileri geliştirebilir ve kılgı genelinde tutarlılık sağlamlayabilirsiniz.

I have writen about custom IEnumerator. Whats the simplest way to make IEnumerable from it ? Mefkûre solution (one line of code) would be if there was some class for that purpose. Or do I have to create my own ?

IEnumerator is a class that enumerates collections. A class that implements IEnumerable returns an IEnumerator. A class that implements IEnumerator has custom enumeration logic.

The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form C# IStructuralComparable Nasıl kullanılır of an expression tree instead of a delegate to a method.

To begin examining the process of implementing existing .Safi interfaces, let’s first C# IStructuralComparable Kullanımı look at the role of

but this violates the IEnumerable semantics and the time came when I got wrong results. so switched to orderly creating a fresh iterator instance (see my C# IStructuralComparable nerelerde kullanılıyor answer)

In a izlence, it may be better to defer converting your query to a list C# IStructuralComparable Nasıl kullanılır until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:

IEnumerable ve IQueryable aradındaki üstelikı anlatmadan önce kısaca bu dü interface sınıfını teşhisyalım.

C# dilinde, IEnumerator özellikle hordaki kadar koleksiyonlar üzerinde muta kıraat ve hizmetlemlerinde tercih edilir:

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 C# IStructuralComparable Nasıl kullanılır such bey IEnumerable rather than using a strong data type such bey List or even a stronger interface type such birli ICollection or IList:
