IStructuralComparable arayüzü, umumiyetle Array ve Tuple üzere veri bünyeları tarafından uygulanır. Bu veri kuruluşları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak önlaştırma yapar.

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.

Note that I split the interface into IReadOnlyMyItem and IWritableMyItem but you don't actually need IWritableMyItem - you could just omit that interface and write:

The main advantage of this comes in the fact that you can'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.

Bey I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does hamiş allow the user to modify the collection. So if the IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I missing something?

Thous leads that your consumer classes are just awaiting interfaces instead of concrete classes and so you hayat change the concrete implementation at a later stage without breaking your public contract (due to performance reasons use an List instead of a LinkedList or vice versa).

Sonuç olarak System.Collections isim yerı şeşnda kontramıza 7 tane non-generic ve 7 adette generic klas çıkmaktadır. Köken önemli olan hak dershaneı harbi yerde kullanmaktır.

So easy, in fact, that I don't need a full column to C# ReadOnlyCollectionBase Temel Özellikleri do it (and if that's all you want from this column, you dirilik skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this C# ReadOnlyCollectionBase Nedir topic does give me is an excuse to talk about several things: how interfaces in .Safi and the compiler work together; how creating generic classes gives you flexibility; how you gönül exploit one of the built-in .Safi interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you can see a way to write it yourself, and this topic lets me do that, too, by showing how you güç create the .Kemiksiz ReadOnlyCollectionBase class. So this column is birli much about providing insight into how .Safi works as it is about doing something practical. Foundation Knowledge

When call the above code. The changes happening in the call ---1 is getting reflected C# ReadOnlyCollectionBase Nasıl Kullanılır the CategoryList and its affecting the call 2 . How sevimli I make the CategoryList kakım ready Only and I am hamiş supposed to change the collection inside the categoryList .But the collection is getting affected .

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are derece guaranteed to be thread safe.

SingleOrDefault(IEnumerable, Func) Returns the only element of a sequence that satisfies a specified condition or a default value if no such element exists; this method throws an exception if more than one element satisfies the condition.

If you need to do more than the InnerList property will let you, the base class Items property will hand you back C# ReadOnlyCollectionBase Kullanımı the whole List. As 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 C# ReadOnlyCollectionBase Kullanımı of the collections.
