I'm going to start by being perverse and pretending that the ReadOnlyCollectionBase class doesn't exist. If that were true and you wanted to create a read-only collection, you'd create a class that only returned an Enumerator object. A class that just implements IEnumerable is, according to my definitions, a read-only collection class. Generating that GetEnumerator object from your class isn't difficult if you keep your class data in a class that itself implements IEnumerable -- a List, for instance. If you do keep your data in a List, then you birey use the List GetEnumerator method to retrieve an Enumerator object, which you dirilik then return to the program using your class. Listing 1 başmaklık the basics of this class (I've called it PhvReadOnlyList).

read this question and don't want to read swathes of API docs yet still understand what the intent is. It's also really important to minimize code clutter - so things like ReadOnlyCollection are dubious at best.

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:

Nedeniyle güç istenirse Array, azca bellek kullanmaı istenirse List tercih edilmelidir. şayet koleksiyona eklenicek tip mukannen bileğilse ArrayList kullanılabilir. Ama aynı nöbetlevi generic listemizde mukabillayabilme yetisine sahiptir.

Any idea why IList doesn't inherit from ICollection? Since the latter is basically IEnumerable plus Count, and since IList already özgü a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would have C# ReadOnlyCollectionBase Nedir allowed someone with an IList to know how many items to expect from an enumeration.

So when i have this piece of code what is the easiest or best way to make it a read only collection?

This sevimli be a problem when your class katışıksız some invariants (guarantees about what it does and the veri it C# ReadOnlyCollectionBase Nedir holds) birli it cannot make guaranteed if other classes birey change its internals willy nilly.

Enumerating through a collection is intrinsically hamiş a thread-safe procedure. Even when a collection C# ReadOnlyCollectionBase Temel Özellikleri is synchronized, other threads hayat still modify the collection, which causes the enumerator to throw an exception.

Chances are, you'll never notice this difference, but if this is a hot-spot in your code and requires every last bit of performance you dirilik squeeze out of it, why not use an Array instead? That would be faster still.
