Properties Current Gets the element in the collection at the current position of the enumerator.
Understanding the intricacies of IEnumerable and IEnumerator is fundamental for any C# developer aiming to master collections and iterators in .
C# Generics’teki Covariance ve Contravariance, bir temel dershaneın beklendiği yerde türetilmiş bir dershaneı kullanım becerisini (Covariance) yahut türetilmiş bir derslikın beklendiği yerde bir temel sınıfı kullanma becerisini (Contravariance) söyleyiş paha.
So, what does this have to do with yield? Under the hood, any method that contains a yield statement is converted into a class that implements IEnumerator. So suppose I have the following method:
The rules of alliteration in Germanic poetry birli they pertain to single syllable triple consonant clusters starting with the letter s
One thing that might stand out to you is the use of the switch statement in the MoveNext function. If that strongly resembles a finite state machine to you, that’s because it is one.
These changes in my thinking enabled me to write some of the code in my career that I am most proud of, so I’d like to C# IEnumerator nerelerde kullanılıyor take the opportunity to try to demystify these concepts a bit, and maybe they’ll help you consider your day to day problems from new angles.
IEnumerator is an implementation of the Iterator C# IEnumerator nerelerde kullanılıyor pattern. This is a pattern that shows up over and over again in programming languages. I’d be willing to bet that if your C# IEnumerator nerelerde kullanılıyor favorite language has a standard library, somewhere C# IEnumerator Nasıl kullanılır in there exists some version of the iterator pattern.
IEnumerable katışıksız just one method whereas IEnumerator katışıksız 2 methods (MoveNext and Reset) and a property Current. For easy understanding consider IEnumerable birli a box that contains IEnumerator inside it (though derece through inheritance or containment). See the code for better understanding:
This will get you into trouble though when people expect successive calls to GetEnumerator to return different enumerators vs. the same one. But if it's a one time only use in a very constrained scenario, this could unblock you.
an IEnumerator [transformed into a funky class by the compiler] and kakım such cannot have a ref value. The top function could have been written as such:
Yine Kullanılabilirlik: Generic sınıflar ve metotlar farklı veri tipleri midein kullanmayı planladığınız yinelenen kodu azaltır.
In this case you have to use yield return new WaitForSeconds because that's how WaitForSeconds is intended to work. Yielding gives up an enumerator to the calling method, which is C# IEnumerator neden kullanmalıyız then free to enumerate it.
