This doesn't create a copy of list. ReadOnlyCollection doesn't copy the veri, it works directly on the supplied list. See documentation:
I had a client recently who wanted me to create a class that exposed a read-only collection through one of the class properties. While my client was willing to let other programs loop through that collection and retrieve items from the collection by position, he didn't want to let those programs add or remove items from the collection. In the Microsoft .Kupkuru Framework 4.5 you sevimli use the read-only collections that Eric Vogel covered in an earlier C# Corner column, "The New Read-Only Collections in .Kupkuru 4.5," to define that property. My client, however, was working with the .Kupkuru Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .Safi you birey also create a read-only class from an existing List just by calling your List's AsReadOnly method. However, if you need something special (a List that users dirilik add items to but not remove items from), inheriting from the ReadOnlyCollectionBase class makes that very easy to do.
then sure, no harm will be done if you just return the collection directly. I C# ReadOnlyCollectionBase Kullanımı generally try to be a bit more paranoid than that though.

The single line of code required by my extension method just instantiates my PhvReadOnly class (using the datatype C# ReadOnlyCollectionBase Temel Özellikleri that the extension method saf deduced), passing whatever IList object the extension method is being used on.

Does this double well potential contradict the fact that there is no degeneracy for one-dimensional bound states?
So when i have this piece of code what is C# ReadOnlyCollectionBase Temel Özellikleri the easiest or best way to make it a read only collection?

SingleOrDefault(IEnumerable, Func) Returns the only element of a sequence that satisfies a specified condition or a default value if no such element exists; this method throws an exception if more than one element satisfies the condition.

Chances are, you'll never notice this difference, but if this is a hot-tanıtımcık in your code and requires every last bit of performance you dirilik squeeze out of it, why not use an Array instead? That would be faster still.
