Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Yaşama someone just walk me through the meaning of each line. Thanks

I understand why IQueryable is better choice for "out-of-memory" veri but I am struggling to understand why IEnumerable is better for "in-memory" veri? I still think it's better to get filtered veri than to get get veri and apply filter.

While it might seem that only array types emanet make use of this construct, the truth of the matter is

When you implement enumerator logic in any of your collection class, you implement IEnumerable (either generic or non generic).

Örneğin, bir List veya ArrayList kabilinden koleksiyonların dâhilindeki verileri sıralı bir şekilde kaldırmak yahut belirli bir koşula bakılırsa filtrelemek dâhilin IEnumerator kullanılabilir. Bu, nominalm ihya sürecinde verimliliği artırır ve kodun okunabilirliğini iyileştirir.

" This is false, because the where clause is getting called on an IEnumerable and C# IStructuralComparable nerelerde kullanılıyor that only knows how to loop through objects which are already coming from the database. If you made the return of AllSpotted() and the parameters of Feline() and Canine() into IQueryable, then the filter would happen in SQL and this answer would make sense.

But if your class cannot act like a collection then provide a public IEnumerable property for its elements:

The most conservative approach would be for you to C# IStructuralComparable Kullanımı cache all the items inside your new enumerable, to handle C# IStructuralComparable nerelerde kullanılıyor enumerators that hayat only be enumerated once, so there is no general class for this in the runtime.

The first method advances to the next object in the IEnumerable object that created the enumerator, returning false if it's done, and the second returns the current object.
