So if we have IEnumerable as parameter of any method, we birey pass any collection types to the function. Ie we sevimli have method to operate on abstraction not any specific implementation.
Koleksiyonlar Ortada Gezinmeyi Katkısızlar: IEnumerable, koleksiyonlar ortada kolayca gezinmenizi sağlar. GetEnumerator metodu ile koleksiyonun her bir elemanına erişebilir ve bu elemanlar üzerinde muamele yapabilirsiniz.
IEnumerable interface’i sebebiyle bir derslik itere edilebilir özellik kazanmaktadır. Pekâlâ bir dershaneın itere edilebilirlik özellik kazanması neydi?
IEnumerable execute a select query on the server side, load veri in-memory on a client-side and then filter veri
An Enumerable is a class that dirilik give you Enumerators. It özgü 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.
Basically it başmaklık a method to get the next item in the collection. It doesn't need the whole collection to be in memory and doesn't know how many items are in it, foreach just keeps getting the next item until it runs out.
The "inner" member does derece have "Animal" instances in it, but rather "Species" instances, which was very strange for me. The "outer" member does contain "Animal" instances. I presume that the two delegates determine which goes in and what goes out of it?
It is a best practice to implement IEnumerable and IEnumerator on your collection classes to enable the foreach (For Each in Visual Basic) syntax, C# IStructuralComparable nerelerde kullanılıyor however implementing IEnumerable is not required. If your collection does not implement IEnumerable, you must still follow the iterator pattern to support this syntax by providing a GetEnumerator method that returns an interface, class or struct.

Oh sure, you güç use it to create your own custom collection types. But for everyday stuff, it probably isn't kakım useful birli the collections C# IStructuralComparable nerelerde kullanılıyor derived from it.
Expression trees are a very important construct in C# and on the .Safi ortam. (They are important in general, but C# makes them very useful.) To better understand the difference, I recommend reading about the differences between expressions

The most conservative approach would be for you to cache all the items inside your new enumerable, to handle enumerators that dirilik only be enumerated once, so there is no general class for this in the runtime.
Here is why it loads twice birli fewer items as the first example on average. Let's say probability to find element at any position in the range of files is the same.
