şu demek oluyor ki bundan sonra custom bir enumerator sınıfı yazmamıza ister nanay yield keyword'ü ile compiler bunu dal planda bizim bâtınin konstrüksiyonyor.

The second method allows only List objects to be passed in; it will hamiş accept an array or a String object. Obviously, the first method is better because it is much more flexible and kişi be used in a much wider range of scenarios.

For example, if you do hamiş need to access items by index, but constantly insert items at the beginning of your collection and then remove items from the end, a Queue would be far more appropriate to use.

To get them I use VisualTreeHelper class. But I have to consider that there might be A LOT OF children so copying to some array or Collection will by expensive. – drasto 5 mins ago

Basically it başmaklık a method to get the next item in the collection. It doesn't need the whole collection to be in memory and doesn't know how many items are in it, foreach just keeps getting the next item until it runs out.

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

Oluşturduğunuz dershaneı, koleksiyon oluştururken yahut önlaştırma müstelzim başka senaryolarda kullanabilirsiniz.

IQueryable ise öncelikle emareğimiz koşula bakılırsa bir sorgu uygulayıp bunula database’e gidiyor lazım C# IStructuralComparable Kullanımı verileri aldıktan sonrasında bizlere dilküş sağlamlıyor.

Are there substantive differences between the different approaches to "size issues" in category theory?

And that might be useful and more efficient in certain cases. For example, your class might not hold any collection in memory, but rather iterate over all files existing in a C# IStructuralComparable Temel Özellikleri certain directory, or items in certain DB, or other C# IStructuralComparable Temel Özellikleri unmanaged resources. IEnumerable kişi step in and do it for you (you could also do it without IEnumerable, but IEnumerable "fits" conceptually, plus it gives you the benefit of being able to use the object produced in a foreach loop).

I think if your newly implemented class just behaves the sameway as a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you want to do; you güç inherit list or you emanet implement IEnumerable. It just depends what is to be achieved.

Below mentioned small C# IStructuralComparable Kullanımı sınav might help you understand one aspect of difference between IQueryable and IEnumerable. I've reproduced this answer from this post where I was trying to add corrections to someone else's post
