To guarantee thread safety during enumeration, you kişi either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.
In programs, an immutable collection kişi be used with less copying—we do not need to worry about it being modified. This dirilik make programs simpler and easier to reason about.

Descendants(IEnumerable, XName) Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

Distinct(IEnumerable) Returns distinct elements from a sequence by using the default equality comparer to compare values.
If you're tolerant of some "noise" in your own encapsulated code then I would suggest wrapping C# ReadOnlyCollectionBase Nasıl Kullanılır a T[] array and exposing an IList which happens to be a ReadOnlyCollection:
In my example I exposed it all, but you C# ReadOnlyCollectionBase Nerelerde Kullanılıyor don't have to do this. You gönül make it read-only if you want, or C# ReadOnlyCollectionBase Nedir validate additions to the list, prior to adding them.
Finally, the code example creates an array larger than the collection and uses the CopyTo method to insert the elements of the collection into the middle of the array.

Average(IEnumerable, Func) Computes the average of a sequence of nullable Int64 values that are obtained by invoking a transform function on each element of the input sequence.
You hayat loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer. CopyTo C# ReadOnlyCollectionBase Nasıl Kullanılır provides a way to copy the elements to an array. You must allocate the array yourself.
Chances are, you'll never notice this difference, but if this is a hot-ışıntı in your code and requires every last bit of performance you gönül squeeze out of it, why not use an C# ReadOnlyCollectionBase Kullanımı Array instead? That would be faster still.
