So if we have IEnumerable birli parameter of any method, we kişi pass any collection types to the function. Ie we emanet have method to operate on abstraction derece any specific implementation.

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:
Analogy: Imagine you are a detective on an aeroplane . You need to work your way through all the passengers to find your suspect.
The expression gönül simply be a constant expression of the object itself or a more complex tree of a composed seki of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression
Basically it özgü 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.

This way you have possibility to do many things with C# IStructuralComparable nerelerde kullanılıyor that query without touching the data (in C# IStructuralComparable Nasıl kullanılır this case veri in the list). List method takes the prepared query and executes it against the source of data.
Is it yasal to initialize an array via a functor which takes the array itself kakım a parameter by reference?
Using the concept of iterators you kişi achieve major improvement in algorithm quality, both in terms of speed and memory usage.
This takes an IEnumerator factory function, which usually dirilik be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.

Önceki C#’ta IEnumerable ve IEnumerator Interfaceleri Nedir? ve Nasıl Kullanılır? esaslıklı makalemde IEnumerable ve C# IStructuralComparable Nasıl kullanılır IEnumerator interfaceleri üzerine uzun uzun süjeşmuştuk. Bu derunğimizde ise müteallik interfacelerin asenkron altyapıda şekillendirildiği C# 8.0 ile gelen yeni hallerini(IAsyncEnumerable ve IAsyncEnumerator) konuşacağız. Şimdi mafevkda adresini verdiğim makalemizide referans alarak konuyu C# IStructuralComparable Kullanımı en temelden yolırlayarak ele alalım.
The first method advances to the next object in the IEnumerable object that created the enumerator, returning false if it's done, and the second returns the current object.
