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.
Also, it casts IList to IList which has the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is not guaranteed and emanet lead to brittle code.
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 hamiş, copying it to an array, sorting that, clearing the IList, and re-adding the items.
This will allow me to do generic processing on almost any array in the .Kemiksiz framework, unless it uses IEnumerable and hamiş IList, which happens sometimes.
so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This C# IList Kullanımı is to reduce dependency on details that might change in the future.

If you're working within a single method (or even in a single class or assembly in some cases) and no one C# IList Nasıl Kullanılır 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 C# IList Nedir 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.
You might want to have an IOrderRepository that defines a C# IList Nasıl Kullanılır collection of orders in either a IList or ICollection. You could then have different kinds of implementations to provide a list of orders birli long C# IList Neden Kullanmalıyız bey they conform to "rules" defined by your IList or ICollection.
In collections of contiguous elements, such bey lists, the elements that follow the insertion point move down to accommodate the new element.
There is a complication though that dynamic dirilik't see explicit implementations, so something gönül implement IList and IList-of-T and yet still be completely unusable from dynamic.
