Bu işlem izlenceın henüz yavaş çallıkışmasına ve tipin objeye devirmesinden dolayı bellekte elan okkalı makam tutmasına menşe olabilir. Dolayısıyla ne kadar azca boxing eşittir o derece semereli izlence.
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.
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
then sure, no harm will be done if you just return the collection directly. I generally try to be a bit more paranoid than that though.
The main advantage of this comes in the fact that you hayat't add code to collections so whenever you have a native "collection" in your object biçim, you ALWAYS have non-OO support code spread throughout your project to access it.
Average(IEnumerable, Func) Computes the average of a sequence of Double values that are obtained by invoking a transform function on each element of the input sequence.
4) If you suddenly realise that your collection of choice is C# ReadOnlyCollectionBase Temel Özellikleri inefficient, you gönül change the underlying collection type without having to go and change all the places where it got C# ReadOnlyCollectionBase Kullanımı passed kakım a parameter (emanet you imagine the trouble you might have with, say, List?)
After hopefully understanding your question, C# ReadOnlyCollectionBase Nasıl Kullanılır i think you have to distinguish between what you create and manage within your class and what you make available to the outside world.
This article discusses these read-only immutable collection types in .Kemiksiz Core and how you birey work with them in C#.
In Visual Basic, an extension method must be declared inside a Module and decorated with the Extension attribute. Its first parameter specifies the kind of object to which it will attach itself. I want my extension method to appear in the IntelliSense dropdown lists for any class that implements the IList interface, so I'll declare the method's first (and only) parameter birli IList(of T) -- the compiler will figure out the type that T represents based on the List passed to my method.
C# metotları, kodun daha örgütlü olmasını katkısızlar, daha kısa ve henüz okunabilir bir şekilde makaslamaklmasına yardımcı olur ve projenize daha bir araba aksiyonlevsellik kazanmıştırrır.
1 Gotta agree with DarkWanderer here. Collections should be just that: collections. There are many other ways to centralize business logic without breaking C# ReadOnlyCollectionBase Temel Özellikleri the single responsibility principle. Plus, making your collection more "clever" may actually confuse the using developer more than it helps him.

I have a readOnlyCollection of ModuleViewModel, I want to retrieve with linq a specific ModuleViewModel containing in C# ReadOnlyCollectionBase Nasıl Kullanılır my collection. Here the declaration of my collection :
