C# IEnumerable Nasıl Kullanılır Ile ilgili detaylı notlar

[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.

I noticed that if I use IEnumerable, when I debug and inspect "yığın", which in that case is the IEnumerable, it saf some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.

So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.

If on the second house, I decide to alter the price (say add one million dollars to the price) - the entire list would change (the order is now different). "one at a time" and "all of them right now" are two different things.

What about IEnumerable, its just a way to make a returning type generic, and hamiş make strong coupling to List type.

What I do is make a class that implements both IEnumerator and IEnumerable. Make GetEnumerator() return itself and you hayat iterate it like düzgülü.

Şimdi makalemizin bu noktasına gelen okuyucularımın kafalarında muhakemesini yaptıkları işşmalar şöhretırım üç aşağı C# IEnumerable Temel Özellikleri beş yukarı dunda hesap ettiğime benzeri niteliktedir.

Is it legal to initialize an array via a functor which takes the array itself as a parameter by reference?

In a izlence, it may be better to C# IEnumerable Nerelerde Kullanılıyor defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do C# IEnumerable Temel Özellikleri this:

Kendi tanılamamladığımız “Person” tipinden “Current” property’si.Gayemiz yapıcı metotla almış olduğumız collection üzerinde gezerken ele aldığımız nesneyi(Person) IEnumerator’dan gelen “Current” property’sine ulaşmak,olası bir hata durumunda ise tıpkı collectionlarda evetğu üzere “IndexOutOfRangeException” hatası fırlatmak.

Generally, don't worry about what's actually in the IEnumerables, as it will be completely different from your actual code. C# IEnumerable Nerelerde Kullanılıyor 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 hamiş need to read the whole file. Or if you're reading the results from a large SQL query you birey sınır your memory use to a single record.

You should still avoid declaring the parameter type bey List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
