Implementation of IEnumerable is generally the preferred way for a class to indicate that it should be usable with a "foreach" loop, and that multiple "foreach" loops on the same object should operate independently.
Many of the LINQ methods, including Where, use deferred execution. In this case you yaşama think of the IEnumerable as a query, rather than the actual result seki.
So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.
A. We iterate the list in different way, foreach dirilik be used for IEnumerable and while loop for IEnumerator.
By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.
The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:

It saf a good C# IEnumerable Nerelerde Kullanılıyor performance when you are iterating through big objects or collections because it does not load the entire object to memory in order to make iteration.
Nobody mentioned one crucial difference, ironically answered on a question closed kakım a duplicated of this. IEnumerable is read-only and List is hamiş.
In a izlence, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas C# IEnumerable Nedir more than once, I'd do this:

I think if your newly implemented class just behaves the sameway kakım a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you want to do; you kişi inherit list or you birey implement IEnumerable. It just depends what is to be achieved.
