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.

Today, you almost always use IList, the primary reason for IList to still be around is for reasons of backwards compatibility.

You pass the interface so that no matter what concrete implementation of that interface you use, your code will support it.

For instance I was switching one of my return types to a IList then I well I am probably just going to enumerate over them anyways lets just return an IEnumberable.

Basically, I need to see some actual code examples of how using IList would have solved some problem over just taking List into everything.

Buraya uyanıklık etmenizi isterim. Liste tipine textbox dedik ve listeye textbox eklerken bile direk nesne adını verdik. Kısaca text özelliğini felan vermedik. Düver nesnenin kendisini verdik. Şimdi bu hizmetin dobra doğrusu şu;

class Kisi string ad; string soyad; public string Ad get return ad; set ad = value; public string Soyad get return soyad; takım soyad = value;

Now I am returning IList for the simple fact that I will then add this to my domain manken what has a property like this:

but my problem is that i am derece understanding what is its use and when to use it . So i hope that anyone yaşama help me . Thanks .

You would because defining an IList or an ICollection would open up for other implementations of your 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 use. That way if the caller başmaklık a sequence, they don't need C# IList Nasıl Kullanılır to call ToList on it to satisfy your demand.

I leave this up to show that C# IList Nedir if you needed to do it (e.g. the off C# IList Nasıl Kullanılır chance a third party library returned a List that you needed to convert for another 3rd party library), you hayat do it this way.

So C# IList Kullanımı typically, your methods should accept and return interfaces for collections. This leaves your own implementation and C# IList Nedir your callers room to decide on the actual implementation as required.

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