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.

Same principle as before, reversed. Offer the bare minimal that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

Interface’ler üzerine elan bir küme bilim olmak isterseniz, bayağıdaki kaynaklara dide atabilirsiniz:

Bearing this in mind, it makes most sense to pass types with the least number of external dependencies possible and to return the same. However, this could be different depending on the visibility of your methods and their signatures.

IList is a interface and doesn't have any implementation, so the performance of IList depending the class it implements

List is a specific implementation of IList, which is a container that güç 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 argument, you only specify that you need certain capabilities of the container. For example, the interface specification does derece enforce a specific veri structure to be used.

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

For collections you should aim to use IEnumerable where possible. This gives the most flexibility but is not always suited.

Then later if you decide to convert the actual veri store C# IList Nedir from a List to a Dictionary and expose the dictionary keys bey 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 mesele! If you expose the List bey an IEnumerable you emanet comfortably predict that your collection is not being C# IList Kullanımı modified externally. That is one of the powers of exposing List as any of the above interfaces.

This argument only works if you write your own implementation of IList from sratch (or at least without inheriting C# IList Neden Kullanmalıyız List)

Less ridiculous way to prove that an Ascii C# IList Kullanımı character compares equal with itself in Coq more hot questions

This will help if you decide to change the C# IList Kullanımı 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 change.

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