Bu iş izlenceın elan yavaş çtuzakışmasına ve tipin objeye devirmesinden dolayı bellekte henüz ziyade mahal tutmasına vesile evet. Dolayısıyla ne denli azca boxing eşittir o derece cömert izlence.
A note. Read-only status is hamiş transferred to other references. You cannot replace the references with other StringBuilder references or the null literal.
I avoid using ReadOnlyCollection kakım much as possible, it is actually considerably slower than just using a normal List.
then sure, no harm will be done if you just return the collection directly. I generally try to be a bit more paranoid than that though.
Well, there is a way. It ain't pretty bey it adds extra stuff on your domain sistem, but I just checked and it works.
Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Int32 values that are obtained by invoking a transform function on each element of the input sequence.
Bu makalede, C# metotlarının niye kullanıldığı, ne ustalıke yaradığı ve nasıl özellikler sunmuş olduğu karşı henüz detaylı bilgi vereceğim.
After hopefully understanding your question, i think you have to distinguish between what you create and manage within your class and what you make available to the outside world.
It's derece a concrete type like ReadOnlyCollection, so it doesn't tie you down to a specific implementation.
When call the above code. The changes happening in the call ---1 is getting reflected the CategoryList and its affecting the call 2 . How birey I make the CategoryList as ready Only and I am not supposed to change the collection inside the categoryList .But the C# ReadOnlyCollectionBase Nasıl Kullanılır collection is getting affected .
However, the syntax is awkward. Adding an extension method dirilik simplify that syntax tremendously. Extension methods have at least three convenient features: The first is that they attach themselves to whatever C# ReadOnlyCollectionBase Temel Özellikleri classes you specify, automatically appearing in the IntelliSense dropdown lists for those objects; second, they're automatically passed whatever object they're called from birli their first parameter; third, when an extension method is used with C# ReadOnlyCollectionBase Nedir a generic class (for instance, List), the method automatically figures out the veri type of the generic parameter.
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 C# ReadOnlyCollectionBase Nedir above the base collection, where the generic features would simply derive from casting from the underlying object instances of the base collection.
You can 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 C# ReadOnlyCollectionBase Nasıl Kullanılır array. You must allocate the array yourself.
Chances are, you'll never notice this difference, but if this is a hot-spot in your code and requires every last bit of performance you sevimli squeeze out of it, why hamiş use an Array instead? That would be faster still.
