A software engineer who is always at a high level of passion with new techs and a strong willing to share with what I have learned.
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.
That's good to know. Also if we implement IEnumerator we have to implement Dispose method. As you said, if sequence is generated, it saf to be disposed off. Thanks a lot!
Bir program zarfında çeşitli bilgi koleksiyonları kullanıldığında, bu koleksiyonlardaki verilere erişmek ve muamele davranmak gereklidir. IEnumerator, bu noktada devreye girerek koleksiyonların elemanlarını tenha yekta dolaşmamızı ve muamelat yapmamızı katkısızlar.
If the last call to MoveNext returned false, Current is undefined. You cannot takım Current to the first element of the collection again; you must create a new enumerator instance instead.
You gönül ask a table to give you a new cursor, and you birey have multiple cursors over the same table at the same time.
2 You most probably mean an IEnumerator in the usage for Coroutines . please read that first C# IEnumerator Önemi Nedir .. there are also tons of tutorials about Coroutines ;)
Do you recognize those methods? It’s entirely possible you’ve never called them, even if C# IEnumerator nedir you have been programming in C# for years. But you use this interface all the time. If you’ve ever used a foreach loop or C# IEnumerator Önemi Nedir called any LINQ methods, you’ve used the IEnumerator interface.
Saçma evetğu bağırsakin bu örneği hiç yazmayacaktım lakin C# IEnumerator nedir hem istedikten sonrasında bir şekilde istediğimizi elde edebileceğimizi hemde “her zaman henüz kısaca yolu vardır” anlayışını açıklamak bâtınin çaldatmaıştırıp kaydetmek istedim.
When using foreach to enumerate via an iterator block that contains a using statement, are the resources disposed of when control leaves the loop?
The compiler performs pattern matching. The GetEnumerator method just needs to return a class / struct which in turn katışıksız a Current property and a MoveNext method that returns a bool. I hayat highly recommend Eric Lipperts blog post about pattern matching
It can take a while to really grok this difference, but just remembering that a list (or array, or whatever) doesn't have any concept of "where you are in the list" but C# IEnumerator nerelerde kullanılıyor an iterator over that list/array/whatever does
If I avoid the foreach loop, call GetEnumerator myself, and don't call Dispose on the enumerator, do I have a guarantee that the finally blocks of the enumerator will run?
This continues up to the max of course.. at which point the returned enumerator says it başmaklık no more items
