IStructuralComparable arayüzü, çoğu kez Array ve Tuple kadar done binaları tarafından uygulanır. Bu done bünyeları, elemanlarının sıralamasını ve yapısını dikkate alarak alınlaştırma yapar.

I agree. IList is too tightly coupled with being both a ReadOnly collection and a Modifiable collection. IList should have inherited from an IReadOnlyList.

Example. In this program, 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 kakım an IList reference field.

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

Sum(IEnumerable, Func) Computes the sum of the sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence.

Kakım per the comments below, you emanet prevent the possibility of downcasting by making IWriteableMyItem and WriteableMyItem private or internal. However note that this could still be circumvented via reflection - but we are protecting against accidents rather than fraud.

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

collection. Sometimes I use an array internally C# ReadOnlyCollectionBase Nerelerde Kullanılıyor 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.

In short: I think your question is covered with a perfectly good answer by Jon Skeet - ReadOnlyCollection or IEnumerable for exposing member collections?

Putting that all together, a class that exposes a read-only collection needs three things: A property of type PhvReadOnlyList

First, some definitions: A read-only collection is like C# ReadOnlyCollectionBase Kullanımı a List in that it supports iterating through the items with a For…Each loop or retrieving an item in the collection by position.

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

So, you sevimli define your collection bey a private C# ReadOnlyCollectionBase Temel Özellikleri field and expose it bey a public readonly property like below bey _parents
