I was thinking about creating a new class derived from ReadOnlyCollection (class ReadOnlyMyCollection : ReadOnlyCollection or class ReadOnlyMyCollection : ReadOnlyCollection) which returns the read-only wrapper class (ReadOnlyMyItem) through the square brackets operator, but either the square brackets operator is hamiş marked as virtual and the return type is hamiş even the same or the constructor doesn't have an IList of the wrapper class (IList) to use. Should I build the class (ReadOnlyMyCollection) from scratch?

The How to Fix Violations suggest i clone the object (which i don't want to do) or 'Replace the array with a strongly typed collection that cannot be changed'. I clicked the link and see 'ArrayList' and adding each element one by one and it doesn't look like you dirilik prevent something adding more.

Summary. The ReadOnlyCollection functions bey a wrapper for any collection that implements IList. It adds a level of indirection that reduces possible changes.

İsimleri farklı olsa da generic sınıflardan sadece 1 tanesi (LinkedList) külliyen farklıdır. ötekiler generic sıfır akrabalarıyla mümasil şekilde çtuzakışmaktadır.

Yapısal eşitlik, koleksiyonların elemanlarının aynı tam ve aynı bileğerlere ehil olup olmadığını denetleme değer, bu nedenle katışıkşık bilgi bünyelarını alınlaştırırken kullanışlıdır.

Nedeniyle ivinti istenirse C# ReadOnlyCollectionBase Temel Özellikleri Array, az zihin kullanmaı istenirse List yeğleme edilmelidir. Eğer koleksiyona eklenicek tip belli değilse ArrayList kullanılabilir. Lakin aynı işlemlevi generic listemizde kontralayabilme yetisine sahiptir.

Finally, the code example creates an array larger than the collection and uses the CopyTo method to insert the elements of the collection into the middle of the array.

In Visual Basic, an extension method must be declared inside a Module and decorated with C# ReadOnlyCollectionBase Kullanımı the Extension attribute. Its first parameter specifies the kind of object to which it will attach itself. I want my extension method to appear in the IntelliSense dropdown lists for any class that implements the IList interface, so C# ReadOnlyCollectionBase Nedir I'll declare the method's first (and only) parameter kakım IList(of T) -- the compiler will figure out the type C# ReadOnlyCollectionBase Nasıl Kullanılır that T represents based on the List passed to my method.

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

Inheriting from a non-generic base class would be ineffecient. If the type was using a non-generic base, all it would be would be a thin layer above the base collection, where the generic features would simply derive from casting from the underlying object instances of the base collection.

You birey loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer. CopyTo provides a way to copy the elements to an array. You must allocate the array yourself.

In the class that exposes a read-only property based on PhvReadOnlyList, you still need an ordinary List, with its Add and Remove methods, so that your class gönül put items in the List both before and after creating a PhvReadOnlyList from it.
