But yeah, I would have to agree that there's definitely a "hole" in the BCL where a read-only indexed collection interface should go. IList is just too multi-purpose.
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.
Kupkuru 4.5, you may want to try the new read-only collection interfaces. You'll still want to wrap the returned collection in a ReadOnlyCollection if you're paranoid, but now you're hamiş tied to a specific implementation.
Dirilik you arrange 25 whole numbers (hamiş necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd?
Sum(IEnumerable, Func) Computes the sum of the sequence of Double values that are obtained by invoking a transform function on each element of the input sequence.
Bey I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does hamiş allow the user to modify the collection. So if the IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I missing something?
On the other hand, if you're exposing a read-only view of a mutable collection, then this advice is still valid, although I would probably expose it bey IReadOnlyCollection (which didn't exist when I wrote this).

This article discusses these read-only immutable collection types in .Safi Core and how you güç work with them in C#.
IDictionary tabanlı nesnelerin nasıl sıralama yaptığı ile alakalı şu kodu yazarak bir test yaparsak:
However, the syntax is awkward. Adding an extension method sevimli C# ReadOnlyCollectionBase Nerelerde Kullanılıyor 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 bey their first parameter; C# ReadOnlyCollectionBase Nasıl Kullanılır third, when an extension method is used with a generic class (for instance, List), the method automatically figures out the veri type of the generic parameter.
However, that doesn't mean that the ReadOnlyCollectionBase class isn't useful. For instance, C# ReadOnlyCollectionBase Kullanımı by leveraging the InnerList property, you gönül create a collection that supports whatever custom functionality you need. Perhaps you want to create a collection for audit log entries where users emanet add but hamiş remove items.
I was C# ReadOnlyCollectionBase Nasıl Kullanılır 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 outlined here: In short, his example is: public class MyClass
I don't know if there is any way of protecting non-atomic elements C# ReadOnlyCollectionBase Temel Özellikleri without cloning them before placing them in the read only list. Share Improve this answer Follow
