If an airline is "countable", this means that there MUST be a flight attendant present on the plane, whose sole job is to count:
What rights does an employee retain, if any, who does hamiş consent to being monitored on a work IT system?
GetEnumerator metodu, bir sınıfa iterasyon gestaltlarını kazandıracak özellikleri barındıran IEnumerator nesnesi dönen bir metotdur.
Analogy: Imagine you are a detective on an aeroplane . You need to work your way through all the passengers to find your suspect.
(bey per Mike P's excellent answer) wrap an enumerator to pretend to be enumerable, there are some things that you sevimli't really do - for example, it is hoped
What I do is make a class that implements both IEnumerator and IEnumerable. Make GetEnumerator() return itself and you kişi iterate it like alışılagelen.
This is a nice videoteyp on youtube which demonstrates how these interfaces differ , worth a watch. Below goes a long descriptive answer for it.
Is "parse out" actually a phrasal verb, and in what context do you use "parse" more hot questions
Where the execution will be performed out-of-process, the logic of the query katışıksız to be represented in veri such that the LINQ provider hayat convert it into C# IStructuralComparable Temel Özellikleri the appropriate form for the out-of-memory execution - whether that's an LDAP query, SQL or whatever.
Bu, mukayyetmın standardını artırır ve olası hataları er aşamalarda tespit etmeyi kolaylaştırır.
Does it bring the whole collection in memory? Or, does it instantiate the element one by C# IStructuralComparable nerelerde kullanılıyor one, birli it iterates over the foreach loop? thanks
The reason, of course, is that someone gönül call the first method passing in an array object, a List object, a C# IStructuralComparable Temel Özellikleri String object, and so on — C# IStructuralComparable Temel Özellikleri any object whose type implements IEnumerable.
If the collection supports indexers, you could also iterate over it C# IStructuralComparable Kullanımı with the classic for loop method but the Iterator pattern provides some nice extras like the ability to add synchronization for threading.
When declaring a method’s parameter types, you should specify the weakest type possible, preferring interfaces over base classes. For example, if you are writing a method that manipulates a collection of items, it would be best to declare the method’s parameter by using an interface such birli IEnumerable rather than using a strong veri type such birli List or even a stronger interface type such kakım ICollection or IList:
