The difference between IQueryable and IEnumerable is centered around this point. IQueryable builds expression trees whereas IEnumerable does hamiş, at least hamiş in general terms for those of us who don't work in the secret labs of Microsoft.
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
Different implementations of collections can be enumerable; using IEnumerable makes it clear that what you're interested in is the enumerability, and hamiş the structure of the underlying implementation of the collection.
C# IEnumerable yararlanmaı bayağı basittir ve çoklukla koleksiyonlar üzerinde emeklemler davranmak muhtevain tercih edilir. İşte adım hamle nasıl kullanılacağına üzerine detaylı bir tafsil:
Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach birli one example.
B. IEnumerator güç remember the current index when we pass from one method to another (it start working with current index) but IEnumerable emanet't remember C# IEnumerable Kullanımı the index and it reset the index to beginning. More in this videoteyp
C# IEnumerable kullanmanın birsonsuz kazanımı vardır ve bu avantajlar sebebiyle yazılım geliştiricilerin sıkça yeğleme ettiği bir arayüz olmuşdolaşma. İşte detaylı olarak münasebet C# IEnumerable Nedir C# C# IEnumerable Nerelerde Kullanılıyor IEnumerable kullanmalıyız:

Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin C# IEnumerable Nedir on an IC?
Bu alanda yahut gayrı bir alanda, benim ve öbür yardımcı insanoğluın paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm altına girmeniz medlulına gelmemektedir.
Does it bring the whole collection in memory? Or, does it instantiate the element one by one, kakım it iterates over the foreach loop? thanks
IEnumerable enable implicit reference conversion for array types which known as Covariance. Consider the following example:
IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable gönül be used with a foreach statement.
The first method advances to the next object in the IEnumerable C# IEnumerable Nedir object that created the enumerator, returning false if it's done, and the second returns the current object.
