Note that, if your API is only going to be used in foreach loops, etc, then you might want to consider just exposing IEnumerable instead.

David MillsDavid Mills 2,41511 gold badge2323 silver badges2525 bronze badges 6 2 The right approach really would have been to offer an ISortableList interface (with methods to sort a portion of the list using some particular comparer), have List implement it, and have a static method which could sort any IList by checking whether it implemented ISortableList and, if derece, copying it to an array, sorting that, clearing the IList, and re-adding the items.
In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.
Buraya dikkat etmenizi isterim. Liste tipine textbox dedik ve listeye textbox eklerken de sütun nesne adını verdik. Doğrusu text özelliğini felan vermedik. Dikme nesnenin kendisini verdik. Şimdi bu meslekin kılıklı kısaca şu;
I thought I'd never need to change from a List but had to later change to use a custom list library for the extra functionality it provided. Because I'd only returned an IList none of the people that used the library had to change their code.

If you are exposing your class through a library that others will use, you generally want to expose it via interfaces rather C# IList Nasıl Kullanılır than concrete implementations.

IList is derece a class; it's an interface that classes kişi implement. The interface itself is just a contract between the consumer of the class and the class itself. This line of code will work:

You cannot sort C# IList Nasıl Kullanılır an IList in-place through the interface except by using ArrayList.Adapter method in my knowledge.
If you're just enumerating over the values, you should be using IEnumerable. Every C# IList Kullanımı type of datatype that güç hold more than one value implements IEnumerable (or should) and makes your method hugely flexible.
The other general reason for using C# IList Kullanımı interfaces is to expose the minimal amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a veri object that implements IList.
