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!).
ShowDialog(); Fevkda formun bir constructor metodu tanılamamlanmıştır. Farklı bir formda çağrılacağı kabilinden aynı formun load event' ında constructor değeri mevdutir. Ve bu şekilde çtuzakışma anında readonly bir değmeselekenin kıymeti kaş edilmiştir. Basıcı kıymetiharbiye ataması mesleklemini teşhismlandığı anda da yapabiliriz.
That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase
List's are a very common datastructure, but creating them in this fashion involves quite a bit of syntactic noise - and it sevimli easily get even worse (e.g.
Passing IList/IDictionaries is generally no good because I hayat't communicate nor enforce the read-only nature of those views (so e.g. IList is actively worse than an array here)
You want to use the yield keyword. You loop through the IEnumerable list and return the results with yeild. This allows the consumer to use the for each without modifying the collection.
Ancestors(IEnumerable) Returns a collection of elements that contains the ancestors of C# ReadOnlyCollectionBase Nedir every node in the source collection.

I've implemented AReadOnlyList bey a read-only property because I'm assuming that if you don't want programs adding C# ReadOnlyCollectionBase Nerelerde Kullanılıyor or removing items from your collection, you probably don't want programs shoving whole new collections into your property, either.

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

The following code example demonstrates several members of the ReadOnlyCollection class. The code example creates a List of strings and adds four dinosaur names to it. The code example then wraps the list in a ReadOnlyCollection.
DefaultIfEmpty(IEnumerable, TSource) Returns the elements of the specified sequence or the specified value in a singleton collection if C# ReadOnlyCollectionBase Nasıl Kullanılır the sequence is empty.
