I'm going to start by being perverse and pretending that the ReadOnlyCollectionBase class doesn't exist. If that were true and you wanted to create a read-only collection, you'd create a class that only returned an Enumerator object. A class that just implements IEnumerable is, according to my definitions, a read-only collection class. Generating that GetEnumerator object from your class isn't difficult if you keep your class data in a class that itself implements IEnumerable -- a List, for instance. If you do keep your veri in a List, then you dirilik use the List GetEnumerator method to retrieve an Enumerator object, which you sevimli then return to the program using your class. Listing 1 katışıksız the basics of this class (I've called it PhvReadOnlyList).

 

In a multithreaded environment, this is even more of an issue, bey one thread birey make changes to the veri while another is trying to read data - you güç easily get inconsistent veri in different threads.

protected virtual ICollection EmployeesInternal get; private seki; = new List(); // this will expose collection contents to public, seemingly unneccessary `Skip` statement will prevent casting back to Collection

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

So when i have this piece of code what is the easiest or best way to make it a read only collection?

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

(There are plenty of other options for wrapping trivially - the birçok C# ReadOnlyCollectionBase Nasıl Kullanılır thing about Skip over Select/Where is that there's no delegate to execute pointlessly for each iteration.)
