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 derece explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.
This will create a new list element for each element in memory, enumerating the IEnumerable and is thus less performant if you only enumerate once - but safer and sometimes the List methods are handy (for instance in random access).
The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:
IQueryable allows for out-of memory things like a remote veri source, such kakım a database or web service.
It başmaklık a good performance when you are iterating through big objects or collections because it does derece load the entire object to memory in order to make iteration.

Oh sure, you emanet use it to create your own custom collection types. But for C# IStructuralComparable nerelerde kullanılıyor everyday stuff, it probably isn't birli useful as the collections derived from it.
a reset on enumerators, but this is largely a design mistake and shouldn't be C# IStructuralComparable nerelerde kullanılıyorC# IStructuralComparable nedir used (it is even a formal requirement in the spec that iterator blocks throw an exception if you call it).
If the collection supports indexers, you could also iterate over it with the classic for loop method but the Iterator pattern C# IStructuralComparable nedir provides some birçok extras like the ability to add synchronization for threading.
