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.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

I avoid using ReadOnlyCollection bey much as possible, it is actually considerably slower than just using a alışılagelen List.

Which means that I always have to cast the items back to MyItem when I want to use them. Also the items emanet be casted into MyItem outside the class.

This base class is provided to make it easier for implementers to create a generic read-only custom collection. Implementers are encouraged to extend this base class instead of creating their own.

You want to use the yield keyword. You loop through the IEnumerable list and return the results with yeild. This allows the consumer to use the for each without modifying the collection.

Ne sınıf nerde kullanılmalı, bu sınıfların farklılıkları neler, performansları nasıl kadar bazı soruları bu makalede yanında arayalım.

Özellikle verilerin muayyen bir sıraya bakılırsa aksiyonlenmesi müstelzim durumlarda, Queue C# ReadOnlyCollectionBase Temel Özellikleri kullanımı mukayyetm projelerinin verimliliğini fazlalıkrabilir.

It's hamiş a concrete type like ReadOnlyCollection, so it doesn't tie you down to a specific implementation.

If you do this then there's nothing C# ReadOnlyCollectionBase Temel Özellikleri stopping your callers casting the IEnumerable back to ICollection and then modifying it. ReadOnlyCollection removes this possibility, although it's still possible to access the underlying writable collection C# ReadOnlyCollectionBase Nedir via C# ReadOnlyCollectionBase Nedir reflection.

ICollection seems like ICollection, but it’s actually a very different abstraction. We found that ICollection was not very useful. At the same time, we did not have an abstraction that represented an read/write non-indexed collection.

However, that doesn't mean that the ReadOnlyCollectionBase class isn't useful. For instance, by leveraging the InnerList property, you sevimli create a collection that supports whatever custom functionality you need. Perhaps you want to create a collection for audit log entries where users sevimli add but hamiş remove items.

For maximum flexibility, my class doesn't specify the data type of the List in which it keeps its actual data. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a veri type that the code refers to bey T. Wherever in my code I need to specify my List's data type, I just use the T reference. Finally, I've chosen to C# ReadOnlyCollectionBase Temel Özellikleri have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.

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