C# ReadOnlyCollectionBase Kullanımı A Gizli Silah

Wiki Article

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 had a client recently who wanted me to create a class that exposed a read-only collection through one of the class properties. While my client was willing to let other programs loop through that collection and retrieve items from the collection by position, he didn't want to let those programs add or remove items from the collection. In the Microsoft .NET Framework 4.5 you emanet use the read-only collections that Eric Vogel covered in an earlier C# Corner column, "The New Read-Only Collections in .Kemiksiz 4.5," to define that property. My client, however, was working with the .NET Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .Safi you birey also create a read-only class from an existing List just by calling your List's AsReadOnly method. However, if you need something special (a List that users emanet add items to but derece remove items from), inheriting from the ReadOnlyCollectionBase class makes that C# ReadOnlyCollectionBase Kullanımı very easy to do.

Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Single values that are obtained by invoking a transform function on each element of the C# ReadOnlyCollectionBase Nasıl Kullanılır input sequence.

Passing IList/IDictionaries is generally no good because I birey't communicate nor enforce the read-only nature of those views (so e.g. IList is actively worse than an C# ReadOnlyCollectionBase Nasıl Kullanılır array C# ReadOnlyCollectionBase Nerelerde Kullanılıyor here)

Koleksiyonların Konstrüktif Kontralaştırması: IStructuralEquatable arabirimi, özellikle diziler ve koleksiyonlar gibi strüktürel data bünyelarının huzurlaştırılması dâhilin kullanılır.

; but this question convinced me to go ahead and announce an open source project I've had in the works for a while (still a work in progress, but there's some useful stuff in there), which includes an IArray interface (and implementations, naturally) that I think captures exactly what you want here: an indexed, read-only, even covariant

C# Queue sınıfı yararlanmaı nispeten basittir ve çeşitli adımları sineerir. Bu adımları akıllıca bir şekilde izleme ederek, Queue klasını mübarek bir şekilde kullanabilirsiniz. İşte temel adımlar ve detayları:

A ReadOnlyCollectionBase instance is always read-only. See CollectionBase for a modifiable version of this class.

C# IStructuralEquatable, C# ReadOnlyCollectionBase Temel Özellikleri özellikle çeşitli veri örgülarının veya koleksiyonların dâhilğinin yapısal olarak mukabillaştırılması müstelzim durumlarda kullanılır. Bu durumlar ortada:

This implementation does derece provide a synchronized (thread safe) wrapper for a ReadOnlyCollectionBase, but derived classes dirilik create their own synchronized versions of the ReadOnlyCollectionBase using the SyncRoot property.

Anlaşılabilirlik ve Yararlanma Kolaylığı: C# Queue'un kıytırık ve anlaşılabilir yapısı, geliştiricilerin kompozitşık medarımaişetlemleri yönetmesini kolaylaştırır.

(There are plenty of other options for wrapping trivially - the birçok thing about Skip over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
