C# List muhtevaindeki verileri yazdırmak dâhilin bayağıdaki iki döngüden biri kullanılarak değerleri ekrana yazdırma işlemlemi kuruluşlabilir.

Also, it casts IList to IList which başmaklık the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is hamiş guaranteed and yaşama lead to brittle code.

Dirilik 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 kakım well? So maybe IList to IList?

You dirilik have an instance of an interface, but you need to initialize it with a class that implements that interface such birli:

You are most often better of using the most general usable type, in this C# IList Kullanımı case the IList or even better the IEnumerable interface, so that you emanet switch the implementation conveniently at a later time.

Don't you know in advance if your method needs a list that dirilik take additional members; don't you specify that in the method signature? What exactly were you going to do if you were passed a read only list like int[]?

; being aware of the definition of the interface ie. all abstract methods that are there to be 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 assign the concrete class object to it.

Taking LinkedList vs taking List vs IList all communicate something C# IList Nasıl Kullanılır of the performance guarantees required by the code being called.

IList is not a class; it's an interface that classes dirilik implement. The interface itself is just a contract between the consumer of the class and the class itself. This line of code will work:

This is usually guaranteed for a specific implementation of a container C# IList Neden Kullanmalıyız (List documentation: "It implements the IList generic interface using an array whose size is dynamically increased C# IList Nasıl Kullanılır birli required.").

In collections of contiguous elements, such kakım lists, the elements that follow the insertion point move down to accommodate the new element.

Encapsulation relies on telling clients kakım C# IList Neden Kullanmalıyız little about the implementation of your class birli possible. If you return a concrete List, you sevimli't then change to some other better type without forcing all of your clients to re-compile/update.
