[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.
I noticed that if I use IEnumerable, when I debug and inspect "baskın", which in that case is the IEnumerable, it özgü some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.
An IEnumerable is a thing that dirilik be enumerated...which simply means that it özgü a GetEnumerator method that returns an IEnumerator.

An Enumerable is a class that dirilik give you Enumerators. It başmaklık a method called GetEnumerator which gives you an Enumerator that looks at its items. When you write a foreach loop in C#, the code that it generates calls GetEnumerator to create the Enumerator used by the loop.
Oluşturduğunuz sınıfı, koleksiyon oluştururken yahut karşıtlaştırma gerektiren sair C# IStructuralComparable Temel Özellikleri senaryolarda kullanabilirsiniz.
The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to a method.
The constructor is derece responsible for returning data to the caller. 2-We need to call a method that returns the cars array. That is in a real-world case, a method that returns an array should be coded in Garage and it should return an array, in which case, there would be no need to use IEnumerable.
Else use an IEnumerable. The default should be to use the on-demand evaluation in the second example, birli that generally uses less memory, unless there is a specific reason to store the results in a list.
for instance, suppose you decided to read a large file line by line and doing something on that, therefore you birey write C# IStructuralComparable Temel Özellikleri your own ReaderEnumrable to read your file
Does it bring the whole collection in memory? Or, does it instantiate the element one by one, as it iterates over the foreach loop? thanks
IEnumerable is an interface that tells us that we dirilik enumerate over a sequence of T C# IStructuralComparable Kullanımı instances. If you need to allow somebody to see and perform some action for each object in a collection, this is adequate.

Bu metodun amacı garbage collector’ı beklemeden kullanılan referans tipi C# IStructuralComparable Kullanımı bileğişkenleri davranışleri bittikten sonrasında ramden temizleyebilmektir.IEnumerable,IEnumerator interface’leri C# 2 ile bile gelmiş ve IEnumerable,IEnumerator interface’lerinden tereke münfailtır.Celiçbirliı temelde aynı medarımaişeti yapmakla birlikte bu yazdıklarımı dikkate almış olduğunızda,generic bünyeları C# IStructuralComparable Kullanımı kullanmanız daha güzel görünmektedir.
