ArrayList: ArrayList sınıfı, kararsız boyutlu ve nesnelerin bir koleksiyonunu saklamak için kullanılır ve IEnumerator ile elemanlarına erişim sağlanabilir.
Kısaca imdi custom bir enumerator klası yazmamıza gerek yok yield keyword'ü ile compiler bunu kayırıcı planda bizim dâhilin örgüyor.
Birli per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.
There are many differences but let us discuss about the one big difference which makes the biggest difference. IEnumerable interface is useful when your collection is loaded using LINQ or Entity framework and you want to apply filter on the collection.
By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.
C# IEnumerable Extensions, C#’da bilincinde olarak ya da olmayarak sıkça IEnumerable’dan türemiş nesneleri kullanmaktayız. Peki nedir bu IEnumerable sorusuna yanıt verecek olursak, IEnumerable interface’i bizlere bir collection üzerinde iterasyon yapabilmemize olanak esenlamaktadır.

Now what makes IEnumerable really stand out is iterator blocks (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state for a single item at a time. So if you want to loop C# IEnumerable Kullanımı over the lines in a very large file, for example, you can write an iterator block to handle the file input.
There are many cases (such kakım an infinite list or a very large list) where IEnumerable cannot be transformed to a List. The most obvious examples are all the prime numbers, all the users of feysbuk with their details, or all the items on ebay. The C# IStructuralComparable nerelerde kullanılıyor difference is that "List" objects are stored "right here and right now", whereas "IEnumerable" objects work "just one at a time".
Here is a very good article that details the differences between statement lambdas and expression lambdas and discusses the concepts of expression tress in greater depth: Revisiting C# delegates, expression trees, and lambda statements vs. lambda C# IStructuralComparable Kullanımı expressions.."
The reason, of course, is that someone güç call the first method passing in an array object, a List object, a String object, and so on — any C# IStructuralComparable Kullanımı object whose type implements IEnumerable.

Siz C# IStructuralComparable Temel Özellikleri bile benim kabil çeşitli .Kemiksiz platformlarında çeşitli uygulamalar geliştirdiyseniz ve kullandığınız classların arkasındaki mimariyi merak ediyor,eliniz her seferinde F12’ye gidiyorsa :) IEnumerable ve IEnumerator interfacelerine birokkalı öğün balya gelmiş,ve tekrar siz bile benim kabil o kısaltarak tanılamamlar ile yetinememiş olmalısınız.Ozaman hiç lafı uzatmadan gelelim konuya.
