You güç argue that you may be able to downcast IPerson to Person, but at this point I would answer telling you that you need to follow your own coding conventions: if you defined that you never return Person but IPerson then I would do it this way in the entire code base, and if you need a write-capable Parents property, then you return Person instead (and you avoid a cast later!).
Coming soon: Throughout 2024 we will be phasing out GitHub Issues kakım the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
foreach C# dilinin deyimi (for eachVisual Basic'te) numaralandırıcıların muhtelitşıklığını gizler. Bu nedenle, numaralandırıcıyı doğrudan işlemek adına kullanılması foreach önerilir.
Equals metodunda, Point3D sınıfının X, Y ve Z bileğerlerinin özge nöbetçi ile aynı olup olmadığı denetçi edilir. GetHashCode metodunda ise nesnenin hash kodu oluşturularak yapısal eşitlik alınlaştırmalarında kullanılır.
Ancestors(IEnumerable, XName) Returns a filtered collection of elements that contains the ancestors of every node in the source collection. Only elements that have a matching XName are included in the collection.
Your implementation depends on your needs: - If you don't care about the caller (Class B) from seeing any further changes to the collection then you hayat just clone the collection, hand it out, and stop caring. - If you definitely need the caller (Class B) to see changes that are made to the collection, and you want this to be thread-safe, then you have more C# ReadOnlyCollectionBase Nasıl Kullanılır of a sorun on your hands.
If you're tolerant of some "noise" in your own encapsulated code then I would suggest wrapping a T[] array and exposing an IList which happens to be a ReadOnlyCollection:
instead. I just included IWritableMyItem for completeness (because it shows how you introduce a grup to an interface property that only saf a get, by using new).
So easy, in fact, that C# ReadOnlyCollectionBase Kullanımı I don't need a full column to do it (and if that's all you want from this column, you emanet skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .NET and the compiler work together; how creating generic classes C# ReadOnlyCollectionBase Temel Özellikleri gives you flexibility; how you kişi exploit one of the built-in .Kemiksiz interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you birey see a way to write it yourself, and this topic lets me do that, too, by showing how you kişi create the .Kemiksiz ReadOnlyCollectionBase class. So this column is birli much about providing insight into how .Safi works as it is about doing something practical. Foundation Knowledge
Performans Optimizasyonu: IList, muta erişimini optimize ederek uygulamanın performansını fazlalıkrabilir ve kafa yönetimini iyileştirebilir.
One possibility is to implement your own thread-safe variant of the ReadOnlyCollection to allow locked access, though this will be non-trivial and non-performant if you want to support IEnumerable, and it still
SingleOrDefault(IEnumerable, C# ReadOnlyCollectionBase Temel Özellikleri Func) Returns the only element of a sequence that satisfies a specified condition or a default value if no such element exists; this method throws an exception if more than one element satisfies the condition.
Anlaşılabilirlik ve Kullanım Kolaylığı: C# Queue'un yalınç ve anlaşılabilir C# ReadOnlyCollectionBase Kullanımı dokuması, geliştiricilerin muhtelitşık işlemlemleri yönetmesini kolaylaştırır.
Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Decimal values that are obtained by invoking a transform function on each element of the input sequence.
