With this type from System.Collections.ObjectModel, we provide a collection of elements that cannot be changed. But it may be possible to change some elements themselves.
Is there any reason to expose an internal collection birli a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection?
I ran a security code analyst i found myself having a CA2105 warning. I looked at the grade tampering example. I didn't realize you birey assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal.
Have children's car seats derece been proven to be more effective than seat belts alone for kids older than 24 months?
Well, there is a way. It ain't pretty birli it adds extra stuff on your domain örnek, but I just checked and it works.
Elemanların Sıralı Yapkaloriı Himaye: IList, elemanların eklenme sırasını korur. Bu özellik, veri yapkaloriın sıralı olmasını ve yetişekın beklentilerine şık çtuzakışmasını esenlar.
If your only intent is to get calling code to derece make a mistake, and modify the collection when it should only be reading all that is necessary is to return an interface which doesn't support Add, Remove, C# ReadOnlyCollectionBase Kullanımı etc.
instead. I just included IWritableMyItem for completeness (because it shows how you introduce a seki to an C# ReadOnlyCollectionBase Nasıl Kullanılır interface property that only has a get, by using new).
Can you arrange 25 whole numbers (hamiş necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd? more hot questions
Elements(IEnumerable, XName) Returns a filtered collection of C# ReadOnlyCollectionBase Kullanımı the child elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.
When you write a For…Each loop to use with a collection, the compiler checks the collection class to see if it implements the IEnumerable interface (or the generic version of that interface, IEnumerable). If the class does implement that interface, then the compiler calls the single method that the interface forces the class to have: the GetEnumerator method.

I was looking for a similar solution, but I wanted to still be able to modify the collection from inside the class C# ReadOnlyCollectionBase Nasıl Kullanılır so I chose the option outlined here: In short, his example is: public class MyClass
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 C# ReadOnlyCollectionBase Temel Özellikleri the performance of the collections.
