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

Örneğin oluşturduğumuz bir List içerisine biz Add komutu ile ekleme yapabiliyoruz veya Count ile içerisinde mevcut elemanların saykaloriı alabiliyoruz ve bunu foreach içerisinde kullanabiliyoruz. Peki List bir klas olmasına mukabil foreach nasıl buna icazet veriyor?

The second method allows only List objects to be passed in; it will not accept an array or a String object. Obviously, the first method is better because it is much more flexible and güç be used in a much wider range of scenarios.

C# IEnumerable kullanmaı berenarı basittir ve çoğunlukla koleksiyonlar üzerinde ustalıklemler gitmek bâtınin tercih edilir. İşte aşama aşama nasıl kullanılacağına dair detaylı bir tavzih:

An IEnumerator is a thing that sevimli enumerate: it has the Current property and the MoveNext and Reset methods (which in .Kemiksiz code you probably won't call explicitly, though you could).

IEnumerator is a class that enumerates collections. A class that implements IEnumerable returns an IEnumerator. A class that implements IEnumerator saf custom enumeration logic.

Whenever I'm "stacking" LINQ expressions, I use IEnumerable, C# IEnumerable Temel Özellikleri because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the izlence. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:

For small result sets this is likely to be a single trip, for large ones you're sending a request for more rows from the results, but it doesn't C# IStructuralComparable Kullanımı re-run the entire query.

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical data or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed C# IStructuralComparable Nasıl kullanılır to C# IStructuralComparable Nasıl kullanılır return 'sensible' data if it's able to do so or throw an exception if it emanet't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.
