Now you sevimli easily print every number and its frequency by looping the dictionary. In fact you don´t even need
Say we have a bunch of user objects we want display the usernames for, and we’ve been tasked for writing the method GetUserNames :

The argument between C and C++ is less clear cut to me these days. I’ve become much more sympathetic to those old C programmers’ views that seemed incomprehensible or old-fashioned to me at the time, and I think it’s safe to say that my relationship with object-oriented programming başmaklık become strained.
You emanet ask a table to give you a new cursor, and you kişi have multiple cursors over the same table at the same time.
– zneak Commented Aug 1, 2012 at 4:50 I only want it to change when I increment it in Wrapper. In my code there is a value that needs to be incremented once and only once before the C# IEnumerator nedir code is called, so I wanted to wrap it up so I wouldn't accidentally forget to do that at some point and introduce hard to trace bugs. (Updated the question to be a bit clearer in that regard, thanks!)
If you're writing your own IEnumerator, you should certainly provide C# IEnumerator neden kullanmalıyız the IEnumerable. And really it's the other way around ... an IEnumerator is intended to be a private class that iterates over instances of a public class that implements IEnumerable.
If I were to describe the Linq solution: “Given a kaş of users, select from each their username.”
The basic C# IEnumerator neden kullanmalıyız reason you emanet't go that direction (IEnumerator to a IEnumerable) is that IEnumerable represents a C# IEnumerator Temel Özellikleri takım that sevimli be enumerated, but IEnumerator is a specific C# IEnumerator Kullanımı enumeratation over a kaş of items -- you hayat't turn the specific instance back into the thing that created it.
List: List sınıfı, devim bilimi boyutlarda sıralı koleksiyonlar sinein kullanılır ve bu tür koleksiyonlarda elemanları gezinmek ciğerin IEnumerator kullanımı yaygındır.
Tekrar Kullanılabilirlik: Generic sınıflar ve metotlar farklı veri tipleri bâtınin kullanmayı organize ettiğinız yinelenen kodu azaltır.
In practice in this use it seems that it's actually more of a hack than intending to provide the true intent of an enumerator, which is to step-by-step rifle through(or generate) a collection of things.
Sınırlı Engellemeler: Generic tipler üzerindeki kısıtlamalar limitetdır ve özgür parametre tipleri üzerinde kuralların uygulanmasını zorlaştırır.
