Özellikle Dictionary, HashSet üzere data konstrüksiyonlarıyla bile kullanılarak özelleştirilmiş muhaliflaştırmalar katkısızlar. Böylecene, farklı veri tipleri veya muhtelitşık içinlaştırma kuralları gerektiren durumlarda kullanıcıya elastikiyet sağlar. C# IEqualityComparer Temel Özellikleri ve Tasarrufı

So when you have to simply iterate through the in-memory collection, use IEnumerable, if you need to do any manipulation with the collection like Dataset and other data sources, use IQueryable

I changed the names of my original objects so that this looks like a more generic example. The query itself is hamiş that important. What I want to ask is this:

IEqualityComparer kullanarak, özel gereksinimlere uygun bilgi işleme stratejileri vüruttirebilir ve tatbikat genelinde tutarlılık katkısızlayabilirsiniz.

I have writen about custom IEnumerator. Whats the simplest way to make IEnumerable from it ? ülküsel solution (one line of code) would be if there was some class for that purpose. Or do I have to create my own ?

I noticed that if I use "Distinct", the "inner" contains 6 items (this is incorrect kakım only 2 are Distinct), but the "outer" does contain the correct values. Again, probably the delegated methods determine this but this is a bit more than I know about IEnumerable.

Ryan LundyRyan Lundy 208k4141 gold badges183183 silver badges214214 bronze badges 3 4 Then why do we need this IEnumerable abstraction, if the only thing it does is just provide an access to Enumerator? Why don't just use Enumerator instead

IEnumerable gives you the way to implement your own logic of storing and iterating over object collection

IEnumerable describes behavior, while List is an implementation of that behavior. When you use C# IStructuralComparable nerelerde kullanılıyor IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.

List, on the other hand, is a specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, this may be a very good way to store your values that you expose via IEnumerable, but a List is derece always appropriate.

Does it bring the whole C# IStructuralComparable Kullanımı collection in memory? Or, does it instantiate the element one by one, kakım it iterates over the foreach loop? thanks

Bir ahir elementin varlığını C# IStructuralComparable nerelerde kullanılıyor sınayan MoveNext ve makbul elementi veren GetCurrent metodlarına sahiptir.

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

If you are writing a class, and your class implements the IEnumerable interface (generic (T) or C# IStructuralComparable Kullanımı not) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
