Collections enable you to allocate memory dynamically to store elements and then retrieve C# ReadOnlyCollectionBase Nasıl Kullanılır them using a key or index as needed.
Sam Allen is passionate about computer languages. In the past, his work özgü been recommended by Apple and Microsoft and he katışıksız studied computers at a selective university in C# ReadOnlyCollectionBase Nedir the United States.
I've implemented AReadOnlyList bey a read-only property because I'm assuming that if you don't want programs adding or removing items C# ReadOnlyCollectionBase Nedir from your collection, you probably don't want programs shoving whole new collections into your property, either.

Hassaten, metotlar C# ReadOnlyCollectionBase Temel Özellikleri projenizin hizmetını ve güncellemesini kolaylaştırır ve performansınızı pozitifrabilir. Bu nedenle, C# programlama dilinde metot kullanmak, bir projeyi daha çok ve elan kuvvetli hale getirmenin önemli bir yoludur.
One might not realize that the collection is read-only but the variable pointing to it is hamiş. What a ReadOnlyCollection would mean if I kişi reassign the variable itself to a new collection altogether. +1.
