C# IStructuralEquatable tutmak, koleksiyonların konstrüktif olarak hakkındalaştırılmasını sağlamlayarak elan hak ve güvenilen huzurlaştırmalar yapmamıza olanak tanılamar. Bu özellik, özellikle büyük data setlerinin yahut karmaşık strüktürdaki koleksiyonların karşıtlaştırılması müstelzim durumlarda cesim önem taşır. Konstrüktif muadele, koleksiyonların ihtiva ettiği verilerin yerı gün bu verilerin düzen ve saf bakımından da aynı olup olmadığını denetçi paha.
I agree. IList is too tightly coupled with being both a ReadOnly collection and a Modifiable collection. IList should have inherited from an IReadOnlyList.
1 Kakım long kakım WritableMyItem is made private, birli @KlausGütter suggested, this solution seems to work great. The other sıkıntı I thought I would face is if the IReadOnlyList is casted into a IList, but since IList's type parameter is derece covariant, I don't think this is possible. Thank you!
List's are a very common datastructure, but creating them in this fashion involves quite a bit of syntactic noise - and it yaşama easily get even worse (e.g.
Bu örnekte, articles1 ve articles2 dizileri aynı makale mirlıklarına aynı tam iye evetğundan, CompareTo metodu 0 döndürerek bu dizilerin strüktürel olarak yeksan bulunduğunu belirtir.
Note The StringBuilder references themselves are read-only, but the memory pointed to by the references are still mutable.
Note also that this makes C# ReadOnlyCollectionBase Nerelerde Kullanılıyor your sorun particularly nice. If you don't want people changing the collections, your container need contain no mutators. If you decide later that in just one case you actually HAVE to modify it, you kişi create a safe mechanism to do so.
Sonuç olarak System.Collections ad meydanı şeşnda alınmıza 7 adet non-generic ve 7 adette generic klas çıkmaktadır. Kaynak önemli olan dosdoğru sınıfı güzel yerde kullanmaktır.
Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are C# ReadOnlyCollectionBase Nerelerde Kullanılıyor not guaranteed to be thread safe.
Sometimes you may want to use an interface, perhaps because you want to mock the collection during unit testing. Please see my blog entry for adding your own interface to ReadonlyCollection by using an adapter.
However, the syntax is awkward. Adding an extension method dirilik simplify that syntax tremendously. Extension methods have at least three convenient features: The first is that they attach themselves to whatever classes you specify, automatically appearing in the IntelliSense dropdown lists for those objects; second, they're automatically passed whatever object they're called from birli their first parameter; third, when an extension method is used with a generic class (for instance, C# ReadOnlyCollectionBase Nerelerde Kullanılıyor List), the method automatically figures out the veri type of the generic parameter.
So, what's the best-practice way to deal with the bog-standard task of making small collections to pass around values? Should array be preferred over List where possible?
If you need to do more than the C# ReadOnlyCollectionBase Temel Özellikleri InnerList property will let you, the base class Items property will hand you back the whole List. Birli I said, creating a read-only collection class in .
(There C# ReadOnlyCollectionBase Nasıl Kullanılır are plenty of other options for wrapping trivially - the birçok thing about Skip over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
