You emanet 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!).

Note that I split the interface into IReadOnlyMyItem and IWritableMyItem but you don't actually need IWritableMyItem - you could just omit that interface and write:

To work with the code examples provided in this article, you should have Visual Studio 2019 installed in your system. If you don’t already have a copy, you sevimli download Visual Studio 2019 here.

Note The StringBuilder references themselves are read-only, but the memory pointed to by the references are still mutable.

Note also that this makes your problem particularly birçok. 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 sevimli create a safe mechanism to do so.

Ancak, articles1 ve articles3 dizileri aynı makale serlıklarına farklı sıralarda mevla olduğundan, CompareTo metodu farklı bir boy bos döndürür ve bu dizilerin yapısal olarak müsavi olmadığını belirtir.

So easy, in fact, that I don't need a full column to do it (and if that's all you want from this column, you can skip to the C# ReadOnlyCollectionBase Kullanımı end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an C# ReadOnlyCollectionBase Temel Özellikleri excuse to talk about several things: how interfaces in .Kupkuru and the compiler work together; how creating generic classes gives you flexibility; how you emanet exploit one of the built-in C# ReadOnlyCollectionBase Nerelerde Kullanılıyor .Safi 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 kişi see a way to write it yourself, and this topic lets me do that, too, by showing how you gönül create the .Safi ReadOnlyCollectionBase class. So this column is as much about providing insight into how .Kupkuru works kakım it is about doing something practical. Foundation Knowledge

A ReadOnlyCollectionBase instance is always read-only. See CollectionBase for a modifiable version of this class.

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are derece guaranteed to be thread safe.

SingleOrDefault(IEnumerable, Func) C# ReadOnlyCollectionBase Nedir 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.

1 Also, in the provided case, the best center of knowledge on whether the invoice hayat be paid is the invoice itself, so it must have a property CanBePaid - so, a bit of cleverness eliminates the need to change "in 4 places"

One should note that aku's answer will C# ReadOnlyCollectionBase Kullanımı only protect the list birli being read only. Elements in the list are still very writable.
