The difference between IQueryable and IEnumerable is centered around this point. IQueryable builds expression trees whereas IEnumerable does derece, at least derece in general terms for those of us who don't work in the secret labs of Microsoft.
Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Hayat someone just walk me through the meaning of each line. Thanks
Şimdiye denli .Kemiksiz ile pratik geliştirenler IENumarable ve IENumerator interface kuruluşlarını biryoğun yerde gördük yahut farkında olmadan çok kullandık ama ne aksiyone nimyor münasebet bu boşluk yüzlere ihtiyaç duyulur nerelerde kullanabilirim gibi sorulara bu makalemizde vaziyet vereceğiz.
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.

" This is false, because the where clause is getting called on C# IStructuralComparable Kullanımı an IEnumerable and 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() C# IStructuralComparable Nasıl kullanılır and Canine() into IQueryable, then the filter would happen in SQL and this answer would make sense.
Ya sarıklı, onca yazdın çizdin C# IStructuralComparable Nasıl kullanılır anladıkta dü satır IEnumerable yahut IEnumerator interfacelerini kullanmadın?
On the flip side, it is usually best C# IStructuralComparable Temel Özellikleri to declare a method’s return type by using the strongest type possible (trying hamiş to commit yourself to a specific type). Share Follow
interface’i ise bir sınıfa foreach mekanizması aracılığıyla tanınması midein lazım yetenekleri/nitelikleri kazanmıştırrır. Kısaca enumerator yapkaloriı… Şimdi gelin bu dü interface yapısını ayrıntılıca irdeleyerek, nasıl kullanıldıklarına bileğinelim.
