IEnumerable Vs List In C#: The Differences | TutorialsEU I think ienumerable is poorly named. mathematically, and in computing, an enumerable is anything that maps to a countable set. so outside of .net an iobservable may be enumerable. in .net ienumerable is considered the dual opposite of iobservable in a pull vs push duality. the intention of ienumerable seems to be what java calls iterable, which in my mind is a better name. Ienumerable describes behavior, while list is an implementation of that behavior. when you use ienumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way.

IEnumerable Vs List In C#: The Differences | TutorialsEU The ienumerable and ienumerator interfaces to begin examining the process of implementing existing .net interfaces, let’s first look at the role of ienumerable and ienumerator. Ienumerable<t> is an interface that tells us that we can enumerate over a sequence of t instances. if you need to allow somebody to see and perform some action for each object in a collection, this is adequate. list<t>, on the other hand, is a specific implementation of ienumerable<t> that stores the objects in a specific, known manner. internally, this may be a very good way to store your. I know how to implement the non generic ienumerable, like this: using system; using system.collections; namespace consoleapplication33 { class program { static void main(string[]. Ienumerable is an interface, instead of looking for how to create an interface instance, create an implementation that matches the interface: create a list or an array.

Ienumerable<t> is meant for querying collections only. it is the backbone for the linq framework. it is always an abstraction of some other collection such as collection<t>, list<t>, or array. the interface only provides a getenumerator method that returns an instance of ienumerator<t> that enables the walking of the extending collection one item at a time. the linq extension methods are. Ienumerable is a general purpose interface that is used by many classes, such as array, list and string in order to let someone iterate over a collection. basically, it's what drives the foreach statement. Ienumerable has one property: current, which returns the current element. icollection implements ienumerable and adds few additional properties the most use of which is count. the generic version of icollection implements the add () and remove () methods. Morelinq has ienumerable<t>.foreach and a ton of other useful extensions. it's probably not worth taking the dependency just for foreach, but there's a lot of useful stuff in there.
