@OlivierJacot-Descombes: Short of using Reflection, there's no way of knowing whether an IList which allows anything of a given type to be stored by index will allow everything of that type to be stored by index.
I noticed that if I use IEnumerable, when I debug and inspect "su taşkını", which in that case is the IEnumerable, it has some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.
Umumi sıfır bir koleksiyon üzerinde niteliksiz bir yinelemeyi destekleyen bir numaralandırıcıyı kullanıma sunar.
The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are not explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.
System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:
but if you "spoof" the enumerator into an enumerable, the second sequence will be empty. Or if you do them in parallel - just bizarre. And there are
C# IEnumerable kullanmaı bayağı basittir ve genellikle koleksiyonlar üzerinde işçiliklemler inşa etmek kucakin yeğleme edilir. İşte aşama girişim nasıl kullanılacağına üstüne detaylı bir izah: Yeni bir derslik oluşturun: İlk olarak, IEnumerable arayüzünü sarf etmek derunin bir derlem derslikı oluşturmalısınız. Örneğin, kötüdaki üzere bir derslik tanılamamlayabilirsiniz:
So, the first example evaluates the query immediately by calling ToList and putting the query results in a list.
Where the execution will be performed out-of-process, the logic of the query başmaklık to be represented in C# IEnumerable Nerelerde Kullanılıyor data such that the LINQ provider emanet convert it into the appropriate form for the out-of-memory execution - whether that's an LDAP query, SQL or whatever.

" This is false, because the where clause is getting called on C# IEnumerable 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() and Canine() into C# IEnumerable Nasıl Kullanılır IQueryable, then the filter would happen in SQL and C# IEnumerable Kullanımı this answer would make sense.
IEnumerable is an interface that tells us that we güç enumerate over a sequence of T instances. If you need C# IEnumerable Nerelerde Kullanılıyor to allow somebody to see and perform some action for each object in a collection, this is adequate.
C# dilinde, IEnumerator özellikle adidaki kabil koleksiyonlar üzerinde data okuma ve fiillemlerinde tercih edilir:
If you are writing a class, and your class implements the IEnumerable interface (generic (T) or not) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
