Best practice to create typed collections/lists with internal or private Add, Remove functionality? 2

SingleOrDefault(IEnumerable, TSource) Returns the only element of a sequence, or a specified default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence.

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

Note that I split the interface into IReadOnlyMyItem and IWritableMyItem but you don't actually need IWritableMyItem - you could just omit that interface and write:

Sum(IEnumerable, Func) Computes the sum of the sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence.

Average(IEnumerable, Func) Computes the average of a sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence.

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 C# ReadOnlyCollectionBase Nedir is to return an interface which doesn't support Add, Remove, etc.

Average(IEnumerable, Func) Computes the average of a sequence of nullable Decimal values that are obtained by invoking a C# ReadOnlyCollectionBase Nerelerde Kullanılıyor transform function on each element of the input sequence.

So easy, in fact, that I don't need a full C# ReadOnlyCollectionBase Temel Özellikleri column to do it (and if that's all you want from this column, you dirilik skip to the end C# ReadOnlyCollectionBase Temel Özellikleri where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .Kupkuru and the compiler work together; how creating generic classes gives you flexibility; how you dirilik exploit one of the built-in .Kemiksiz interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you emanet see a way to write it yourself, and this topic lets me do that, too, by showing how you yaşama create the .Kemiksiz ReadOnlyCollectionBase class. So this column is kakım much about providing insight into how .NET works bey it is about doing something practical. Foundation Knowledge

What is the term for when a hyperlink maliciously opens different URL from URL displayed when hovered C# ReadOnlyCollectionBase Kullanımı over?

This answer already assumes you want to return IEnumerable without any reasoning to support that decision.

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
