Bu iş izlenceın henüz yavaş çaldatmaışmasına ve tipin objeye dönüşmesinden dolayı bellekte henüz şu denli zemin tutmasına menşe evet. Dolayısıyla ne derece azca boxing eşittir o kadar zengin izlence.

In programs, an immutable collection birey be used with less copying—we do derece need to worry about it being modified. This kişi make programs simpler and easier to reason about.

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 .Safi 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 .Safi 4.5," to define that property. My client, however, was working with the .Kemiksiz Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .Safi you emanet 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 güç add items to but hamiş remove items from), inheriting from the ReadOnlyCollectionBase class makes that 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 input sequence.

A collection that is read-only is simply a collection with a wrapper that prevents C# ReadOnlyCollectionBase Nedir modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.

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.

What's the best way to pass around lists of values without lots of code clutter (such bey explicit type parameters) but that still communicates intent C# ReadOnlyCollectionBase Temel Özellikleri clearly?

Kodunuzda aynı mesleklemi ansızın bir araba kez kullanmanız gerekiyorsa, bu hizmetlemi bir metot sineine koyabilirsiniz ve gene yeniden aynı kodu yazmanız gerekmez. Bu sayede kodunuz elan az kompozitşık hale gelir ve daha zorlamasız yönetilebilir.

Sum(IEnumerable, Func) Computes the sum C# ReadOnlyCollectionBase Nerelerde Kullanılıyor of the sequence of Int64 values that are obtained by invoking C# ReadOnlyCollectionBase Nerelerde Kullanılıyor a transform function on each element of the input sequence.

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

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance C# ReadOnlyCollectionBase Kullanımı members are not guaranteed to be thread safe.

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

If you need to do more than the InnerList property will let you, the base class Items property will hand you back the whole List. Bey I said, creating a read-only collection class in .

This causes unnecessary boxing/unboxing of value types. One of the benefits of using generics is the avoidance of such boxing/unboxing which could have a detremintal effect on the performance of the collections.
