Don't return a collection directly. Make an accurately named business logic class that reflects the purpose of the collection.
Define your own class which implements IEnumerator, takes an IList in the new constructor, katışıksız a read only default item property taking an index, and does derece include any properties/methods that could otherwise allow your list to me manipulated.
. Why hamiş return IEnumerable? Calling code would have to cast, which they are unlikely to do without knowing the internals of the property they are accessing.
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 emanet prevent something adding more.
Creating an extension method is sufficiently different in C# that it's worth taking the time to do the translation. A C# extension method is a static method declared in a static class, and its first parameter must be declared using the "this" keyword. So the C# version of this method looks like this: public static class PhvExtensionMethods
Anyway, I believe that a domain object should be read-write, because at the end of the day, a domain object describes an entity within the domain and you should be able to access and modify it.
Thous leads that your consumer classes are just awaiting interfaces instead of concrete classes and so you can change the concrete implementation at a later stage without breaking your public contract (due to performance reasons use an List instead of a LinkedList or vice versa).

well, NHibernate dirilik set private class fields and this means that you emanet expose it using a C# ReadOnlyCollectionBase Nedir public property encapsulating the field birli read-only collection.
Figure 1 below displays the members of List. Note that you have a method named Add, so C# ReadOnlyCollectionBase Nerelerde Kullanılıyor you güç easily add authors to the list of authors we’ve created in the preceding code snippet.
However, if you want to access the elements of the IEnumerable collection by index or you want to retrieve the number of elements in the collection, you should use IReadOnlyList birli shown below.
However, a read-only collection doesn't provide Add and C# ReadOnlyCollectionBase Temel Özellikleri Remove methods for changing which items are in the collection, though the items themselves may be updateable (it's the responsibility of the items in the collection to protect themselves from changes).
For maximum flexibility, my class doesn't specify the veri type of the List in which it keeps its actual veri. Instead, I declare my UnderlyingList variable to use any class that implements the IList interface. I've also made this a generic class: Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a data type that the code refers to bey T. Wherever in my code I need to specify my List's veri type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions of the method. Listing 1. The basics of the PhvReadOnlyList class.
