Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.

Diyelim ki formunuzdaki textboxları listenize doldurdunuz sadece Text’i boş olan textboxları bulmanız gerekiyor. Bunun derunin List u kullanmanız gerekir. Mafevkda anlattığımız örneği bayağı olarak yapacak olursak;

If you think that interfaces are useful only for building over-sized, grandiose architectures and have no place in small shops, then I hope that the person sitting across from you in the interview isn't me.

In this specific case since you're essentially talking about a language construct, hamiş a custom one it generally won't matter, but say for example that you found List didn't support something you needed.

List is a specific implementation of IList, which is a container that hayat be addressed the same way kakım a linear array T[] using an integer index. When you specify IList as the type of the method's C# IList Nedir argument, you only specify that you need certain capabilities of the container. For example, the interface C# IList Nerelerde Kullanılıyor specification does derece enforce a specific veri structure to be used.

Inside the method, you should use var, C# IList Nasıl Kullanılır instead of IList or List. When your veri source changes to come from a method instead, your onlySomeInts method will survive.

If your methods form part of an interface, the methods will need to be defined using types available to that interface.

If the parameter type is IList, then the caller başmaklık much more freedom, and dirilik use classes you never heard about, which may hamiş even have existed when your code was written.

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

SQL Mükerrer Kayıtlar Icat etmek ve Silmek, ovam ile sql eğitim setime devam ediyorum. Bu makaslamakmda tablolalarımızdaki mükerrer kayıtları C# IList Kullanımı nasıl bulabileceğimizi ve silebileceğimizi göstereceğim. SQL Mükerrer…

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

This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won't need to update their code since the interface doesn't C# IList Nerelerde Kullanılıyor change.

This works, because only the outer list is created in the first place. You güç then insert individual items that are compatible with IList:
