You dirilik 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!).
This class makes the underlying collection available through the InnerList property, which is intended for use only by classes that are derived directly from ReadOnlyCollectionBase. The derived class must ensure that its own users cannot modify the underlying collection.
I avoid using ReadOnlyCollection as much birli possible, it is actually considerably slower than just using a uygun List.

Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Int32 values that are obtained by invoking a transform function on each element of the input sequence.
What's the best way to pass around lists of values without lots of code clutter (such kakım explicit type parameters) but that still communicates intent clearly?

Any idea why IList doesn't inherit from ICollection? Since the latter is basically IEnumerable plus Count, and since IList already katışıksız a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would have allowed someone with an IList to know how many items to expect from an enumeration.
What is the term for when a hyperlink maliciously opens C# ReadOnlyCollectionBase Nerelerde Kullanılıyor different URL from URL displayed when hovered over?

I was looking for a similar solution, but I wanted to still be able to modify the collection from inside the class so I chose the option C# ReadOnlyCollectionBase Temel Özellikleri outlined here: In short, his example is: public class MyClass
Initializes a new instance of the ReadOnlyCollection C# ReadOnlyCollectionBase Nerelerde Kullanılıyor class that is a read-only wrapper around the specified list.
