So is it faster to use List over IEnumerable? Only if you want to prevent a query from being executed more than once. But is it better overall? Well in the above, Leopards and Hyenas get converted into single SQL queries each
, so if you're doing complicated work to evaluate the enumerable bey you read from it, that work doesn't happen until it's asked for. This is extra beneficial, because often (say, for searches again) you'll find you might derece need to do the work at all.
Different implementations of collections gönül be enumerable; using IEnumerable makes it clear that what you're interested in is the enumerability, and hamiş the structure of the underlying implementation of the collection.
Consider that in your code example a new list created. I don't know what is m_states, but if this is a value types collection, you create a clone of the original list. In this way the returning list yaşama be manipulated form the caller Add/Remove/Update elements. without
Sonunda burada ortaya çıdem sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isimli metot implement ettirilmektedir. IEnumerator ise dayalı sınıfa iterasyon alışverişleminde kullanılacak elemanları ve özellikleri kazanmıştırrmaktan mesul C# IStructuralComparable Kullanımı olacaktır.
static public IEnumerable VerileriGetir() yield return "Pazartesi"; yield return "Salı"; yield return "Çarşamba"; yield return "Perşembe"; yield return "Cuma"; yield return "Cumartesi"; yield return "Pazar"; Şimdi C# IStructuralComparable nerelerde kullanılıyor süflidaki harf bloğunu detaylıca inceleyelim.
Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the program. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:

Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on an IC?
Using the concept of iterators you sevimli achieve major improvement in algorithm C# IStructuralComparable nedir quality, both in terms of speed and memory usage.
Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on an IC?
IEnumerable is an interface that tells us that we hayat enumerate C# IStructuralComparable Kullanımı over a sequence of T instances. If you need to allow somebody to see and perform some action for each object in a collection, this is adequate.
