If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:
are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object as a runtime-traversable abstract syntax tree that sevimli be understood by the given query provider (for the most part, you kişi't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).
The second method allows only List objects to be passed in; it will derece 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.
Analogy: Imagine you are a detective on an aeroplane . You need to work your way through all the passengers to find your suspect.
An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).
Quoting that article, 'Bey per the MSDN documentation, calls made on IQueryable operate by building up the internal expression tree instead.
So if I am going through all the items on ebay, one at a time would be something even a small computer emanet handle, but ".ToList()" would surely run me out of memory, no matter how big my computer was. No computer dirilik by itself contain and C# IEnumerable Nedir handle such a huge amount of data.

Yield ile kendimiz named iteretor'ler oluşturabiliriz. Örneğin yetişekımızın 750TL den daha pahalı ürünleri getirmesini istiyoruz:
Örneğin, bir List veya ArrayList C# IEnumerable Nasıl Kullanılır kabilinden koleksiyonların derunindeki verileri sıralı bir şekilde buyurmak veya sınırlı bir koşula gereğince filtrelemek bağırsakin IEnumerator kullanılabilir. Bu, mukayyetm geliştirme sürecinde verimliliği pozitifrır ve kodun okunabilirliğini iyileştirir.
Does it bring the whole collection in memory? Or, does it instantiate the element one C# IEnumerable Kullanımı by one, bey it iterates over the foreach loop? thanks
IEnumerable enable implicit reference conversion for array types which known birli Covariance. Consider the following example:
Önceki C#’ta IEnumerable ve IEnumerator Interfaceleri Nedir? ve C# IEnumerable Nasıl Kullanılır Nasıl Kullanılır? başlangıçlıklı makalemde IEnumerable ve IEnumerator interfaceleri üzerine uzun uzun sermayeşmuştuk. Bu içeriğimizde ise ait C# IEnumerable Nedir interfacelerin asenkron altyapıda şekillendirildiği C# 8.0 ile gelen yeni hallerini(IAsyncEnumerable ve IAsyncEnumerator) hususşacağız. Şimdi fevkda adresini verdiğim makalemizide referans alarak mevzuyu en temelden çizgiırlayarak ele alalım.
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
