This doesn't create a copy of list. ReadOnlyCollection doesn't copy the data, it works directly on the supplied list. See documentation:
I agree. IList is too tightly coupled with being both a ReadOnly collection and a Modifiable collection. IList should have inherited from an IReadOnlyList.
That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase
As you suggest, my intention is only to protect the collection from direct modification; the collection members are hamiş going to be modified (or needed to be modified).
A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.
Sum(IEnumerable, Func) Computes the sum of the sequence of nullable Int32 values that are obtained by invoking a transform function C# ReadOnlyCollectionBase Nedir on each element of the input sequence.

collection. Sometimes I use an array internally and return an IEnumerable to indicate intent. But most of these approaches have a very C# ReadOnlyCollectionBase Nerelerde Kullanılıyor low signal-to-noise ratio; and that's absolutely critical to understanding code.

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are derece C# ReadOnlyCollectionBase Nedir guaranteed to be thread safe.

I was looking for a similar solution, but I wanted to still be able to modify the collection from inside the class so I chose the option outlined here: In short, his example is: public class MyClass
I don't know if there is any way of protecting non-atomic elements without cloning them before placing them in the read only list. Share Improve this answer Follow
