Örneğin oluşturduğumuz bir List içine tığ Add komutu ile ekleme yapabiliyoruz yahut Count ile içerisinde kâin elemanların sayısını alabiliyoruz ve bunu foreach içinde kullanabiliyoruz. Evet List bir sınıf olmasına mukabil foreach nasıl buna destur veriyor?

An IEnumerable is a thing that sevimli be enumerated...which simply means that it özgü a GetEnumerator method that returns an IEnumerator.

For example, if you do hamiş need to access items by index, but constantly insert items at the beginning of your collection and then remove items from the end, a Queue would be far more appropriate to use.

An Enumerable is a class that emanet give you Enumerators. It başmaklık a method called GetEnumerator which gives you an Enumerator that looks at its items. When you write a foreach loop in C#, the code that it generates calls GetEnumerator to create the Enumerator used by the loop.

So, the first C# IEnumerable Temel Özellikleri example evaluates the query immediately by calling ToList and putting the query results in a list.

Where the execution of a query is going to be C# IEnumerable Nedir performed "in process", typically all that's required is the code (birli code) to execute each part of the query.

Using the concept of iterators you kişi achieve major improvement in algorithm quality, both in terms of speed and memory usage.

Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the tanıtımcık and indicating input and output of the Enum?

Generally, don't worry about what's actually in the IEnumerables, kakım it C# IEnumerable Nerelerde Kullanılıyor will be completely different from your actual code. Only worry about the actual output when you iterate over it :)

Then you'll never have more than one line of the file in memory at a time, and if you finish the loop earlier (perhaps it was a search and you found what you needed) you might derece need to read the whole file. Or if you're reading the results from a large SQL query you kişi limit your memory use to a single record.

By C# IEnumerable Kullanımı "functionally equivalent," I mean that's actually what the compiler turns the code into. You güç't use foreach on baz in this example unless
