[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.
Kısaca daha çok custom bir enumerator sınıfı yazmamıza icap nanay yield keyword'ü ile compiler bunu arka planda bizim yürekin dokumayor.
I understand why IQueryable is better choice for "out-of-memory" data but I am struggling to understand why IEnumerable is better for "in-memory" data? I still think it's better to get filtered data than to get get data and apply filter.
If on the second house, I decide to alter the price (say add one million dollars to the price) - the entire list would change (the order is now different). "one at a time" and "all of them right now" are two different things.
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 C# IEnumerable Kullanımı evaluate the sequence (in this case, when ToList is called) those filters will all be applied.

Gönül a unique position be deduced if pieces are replaced by checkers (emanet see piece color but hamiş type)
Using the concept of iterators you kişi achieve major improvement in algorithm quality, both in terms of speed and C# IEnumerable Nedir memory usage.
This gönül be very useful in certain circumstances, for instance in a massive database table you don't want to copy the entire thing into memory before you start processing the rows.

If you create an IEnumerable, then all rows will be pulled into memory bey objects before running the query.
