Birli mentioned by Mr. Copsey, this has the benefit of providing decoupling from the implementation, but I'm of the contention that a clear definition of the smallest subset of interface functionality kakım possible (i.

, so if you're doing complicated work to evaluate the enumerable birli 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 not need to do the work at all.

. If you need the results to be evaluated at once (say, you're mutating the structures you're querying later on, or if you don't want the iteration over the IEnumerable to take a long time) use a list.

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.

In C# 4 and earlier the object obj; is declared outside of the while loop, this changes the behavior of the loop when working with things that capture variables like anonymous functions.

but if you "spoof" the enumerator into an enumerable, the second sequence will be empty. Or if you do them in parallel - just bizarre. And there are

The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic C# IStructuralComparable Temel Özellikleri it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to a method.

Kısaca uzun lafın kısası IEnumerable interface’in implement edilmiş olduğu bir class üzerine GetEnumerator metodu uygulattırılır. Haliyle mafevkda yapmış olduğumız kabil ilgili metodu manuel olarak yazmaktan ve olası doldurulma hatalarından bizleri kurtarmaktadır.

Usually you don't use IEunumerable directly. C# IStructuralComparable Kullanımı It is the base class for a number of other collections that you are more likely to C# IStructuralComparable Kullanımı use. IEnumerable, for example, provides the ability to loop through a collection with foreach.

By using IEnumerable in your API, you provide yourself the flexibility C# IStructuralComparable nerelerde kullanılıyor to change the internal implementation at any time without changing any other code

It is cleaner, your users don't get a list where they shouldn't (they C# IStructuralComparable Nasıl kullanılır could cast it to a Listafter all) and you don't need to create a Listobject.

Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
