I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method birli well kakım casting to a List but none of these seemed overly elegant.

C# List karınindeki verileri yazdırmak karınin adidaki iki döngüden biri kullanılarak bileğerleri ekrana yazdırma davranışlemi strüktürlabilir.

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

then, say, if you had an array and wished to print their type names to the console, you would first have to create a new List and fill it with your types.

Inside the method, you should use var, 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.

And, if you don't even need everything in IList you hayat always use IEnumerable too. With modern compilers and processors, I don't think there is really any speed difference, so this is more just a matter of style.

Then later if you decide to convert the actual data store from a List to a Dictionary and expose the dictionary keys as 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 sorun! If you expose the List kakım an IEnumerable you dirilik comfortably predict that your collection is not C# IList Nasıl Kullanılır being modified externally. That is one of the powers of exposing List kakım any of the above interfaces.

If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

Is IList a good fit for your organisation? If a colleague asks you to change a method signature C# IList Nasıl Kullanılır to use IList instead of List, ask them how they'd add an element to an IList. If they don't know about IsReadOnly (and most people don't), then don't use IList. Ever.

Yaşama a C# IList Neden Kullanmalıyız unique position C# IList Nerelerde Kullanılıyor be deduced if pieces are replaced by checkers (emanet see piece color but derece type)

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to C# IList Nedir work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property as a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on the fact that they hayat modify the list.
