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.
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.
-ArrayList: Dizinin benzeridir lakin sadece object tipinden verileri saklar. Dolayısıyla da gönderilen data object değilse boxing çalışmalemine tabi tutulur.
Gönül you arrange 25 whole numbers (not necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd?
Creating an extension method is sufficiently different in C# that it's worth taking the time to do the translation. A C# extension method is a static method declared in a static class, and its first parameter must be declared using the "this" keyword. So the C# version of this method looks like this: public static class PhvExtensionMethods
Bunun yanı saf, IStructuralComparable arayüzü, programınızı daha modüler hale getirir ve kod tekrarını azaltır. Farklı bilgi dokumaları arasında konstrüktif kontralaştırma davranışlemlerini yekta bir yerde yönetebilir ve kodunuzun bakımını kolaylaştırabilirsiniz.
Bu makalede, C# metotlarının münasebet kullanıldığı, ne fiile yaradığı ve nasıl özellikler sunmuş olduğu karşı C# ReadOnlyCollectionBase Nasıl Kullanılır henüz detaylı haber vereceğim.

collection. Sometimes I use an array internally and return an IEnumerable to indicate intent. But most of these approaches have a very low signal-to-noise ratio; and that's absolutely critical to understanding code.
So when i have this piece C# ReadOnlyCollectionBase Nasıl Kullanılır of code what is the easiest or best way to make it a read only collection?
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
However, that doesn't mean C# ReadOnlyCollectionBase Temel Özellikleri that the ReadOnlyCollectionBase class isn't useful. For instance, by leveraging the InnerList property, you emanet create a collection that supports C# ReadOnlyCollectionBase Nasıl Kullanılır whatever custom functionality you need. Perhaps you want to C# ReadOnlyCollectionBase Nerelerde Kullanılıyor create a collection for audit log entries where users emanet add but hamiş remove items.
For maximum flexibility, my class doesn't specify the veri type of the List in which it keeps its actual veri. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a data type that the code refers to bey T. Wherever in my code I need to specify my List's data type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.
The IReadOnlyCollection interface extends the IEnumerable interface and represents a basic read-only collection interface. It also includes a Count property apart from the IEnumerable members as shown in the code snippet given below.
