C# IList Nasıl Kullanılır Hakkında Gerçekler Açığa

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list. This code is part of a larger example for the IList interface.

Then the person calling the method is free to call it with any data type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.

Elemanların Sıralı Yapkaloriı Dulda: IList, elemanların eklenme sırasını korur. Bu özellik, veri yapısının sıralı olmasını ve yetişekın beklentilerine yönlü çaldatmaışmasını katkısızlar.

Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?

I tend to follow Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.

Örneğin, adidaki kodda bir IAnimal tipinde bir değişici tanılamamladım ve bu değkârkene Dog ve Cat nesneleri atadım.

Most app-level code (i.e. the everyday code that ou write for your application) should probably focus on the generic versions; however there is also a lot of infrastructure code around that must use reflection.

You gönül look at this argument from several angles including the one of a purely OO approach which says to izlence against an Interface not an implementation. With this thought, using IList follows the same principal kakım passing around and using Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by an Interface in general. If a class implmenting IList needs to be extended or changed, the consuming code does hamiş have to change; it knows what the IList Interface contract C# IList Kullanımı adheres to.

; being aware of the definition of the interface ie. all abstract methods that are there to be C# IList Nasıl Kullanılır implemented by any class inheriting the interface. so if some one makes a huge class of his own with several methods besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case the interface) and C# IList Kullanımı assign the concrete class object to it.

Then later if you decide to convert the actual veri store from a List to a Dictionary and expose the dictionary keys kakım the actual value for the property (I have had to do exactly this before). Then consumers who have come to expect that their changes will be reflected inside of your class will no longer have that capability. That's a big sıkıntı! If you expose the List kakım an IEnumerable you yaşama comfortably predict that your collection is hamiş being modified externally. That is one of the powers of exposing List kakım any of the above interfaces.

By asking for more than you need, you (1) make the caller do unnecessary work to satisfy your unnecessary demands, and (2) communicate falsehoods to the reader. Ask only for what you're going to C# IList Nerelerde Kullanılıyor use. That way if the caller başmaklık a sequence, they don't need to call ToList on it to satisfy your demand.

List sınıfı tanılamamlanırken T tip değemekkenini kırmızıır. Kısaca listenin muhteviyatında ne türden nesne yada bileğmedarımaişetkenlerin olacağını belirler.
