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.

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

Example. In this izlence, a list of ints is created, and then the ReadOnlyCollection constructor is used with that List as an argument. Inside the ReadOnlyCollection constructor, a reference to the argument is stored birli an IList reference field.

If your veri birey be enumerated, you can use Enumerable.ToList method to cast your collection to List and call AsReadOnly on it.

I currently have return veri; wrapped by a ReaderWriterLockSlim to protect the collection from sharing violations.

Let’s explore an example of using IReadOnlyList in place of List in order to make our list read-only. Consider the following class:

Konstrüktif eşitlik, koleksiyonların elemanlarının aynı sırada ve aynı C# ReadOnlyCollectionBase Nasıl Kullanılır bileğerlere mevla olup olmadığını yoklama eder, bu nedenle karmaşık veri binalarını kontralaştırırken kullanışlıdır.

It depends on how much you trust the C# ReadOnlyCollectionBase Kullanımı calling code. If you're in complete control over everything that will ever call this C# ReadOnlyCollectionBase Nerelerde Kullanılıyor member and you guarantee

collection. Sometimes I use an array internally and return an C# ReadOnlyCollectionBase Nasıl Kullanılır 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.

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

In the “Configure your new project” window shown next, specify the name and location for the new project.

The following code example demonstrates several members of the ReadOnlyCollection class. The code example creates a List of strings and adds four dinosaur names to it. The code example then wraps the list in a ReadOnlyCollection.

This C# ReadOnlyCollectionBase Temel Özellikleri 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.
