  • What does enumerable mean? - Software Engineering Stack Exchange
    An enumerable is an object that may be enumerated "Enumerated" means to count off the members of a set collection category one by one (usually in order, usually by name) An enumerable then is an object that can step through a series of other objects one by one
  • Is there a difference between iterable and enumerable?
    If a language has both, "enumerable" almost certainly means something else, probably something more powerful Most likely, it will support the notion of connecting each element with a unique numeric index, and probably it will allow random access (e g retrieving the third element before the first and second ones)
  • Relation and difference between recursively enumerable languages and . . .
    a recursively enumerable language a set of inputs to a Turing Machine for it to recognize Yes, in fact, the recursively enumerable languages are also known as the Turing-recognizable languages They are a strict superset of the decidable languages For example, the halting problem is recognizable, but infamously undecidable
  • Ordered enumeration: IEnumerable or Array (in C#)?
    An enumerable is a device which produces enumerators If an enumerator is abandoned, that does not in any way affect the enumerable If I sell books, and Bob buys a book and only reads it halfway, that doesn't mean that when I sell a different copy of the book to Alice, she has to start reading where Bob left off
  • Why should I use List lt;T gt; over IEnumerable lt;T gt;?
    In my ASP net MVC4 web application I use IEnumerables, trying to follow the mantra to program to the interface, not the implementation Return IEnumerable(Of Student) vs Return New List(Of Student)
  • array - Whats the use of . Any () in a C# List lt; gt;? - Software . . .
    In the comments it was pointed out, rightly so, that Enumerable Count() extension method doesn't need to iterate through all the items if it detects that the enumerable also happens to be an ICollection<T> So in the case of a List<T>, using the Count property or method doesn't actually make a difference IEnumerable Count source:
  • c# - Iterating a class representing a collection: IEnumerable lt;T gt; vs . . .
    public class MyFile : IEnumerable<string> There is something really grating about having a singular (File) represent a plural (IEnumerable)
  • Is implementing IEnumerable required to use foreach on collections?
    Similarly, List<T>, ConcurrentQueue<T>, etc implement IEnumerable and Enumerable<T> So when you say that: And also , arrays are working without implementing IEnumerable this is simply not true Arrays are implementing IEnumerable As for: I have following class that didnt implement IEnumerable but working perfectly with foreach
  • Thread-Safety with Enumerable collections and copies
    Imagine I have an interface IHeapObject: interface IHeapObject { string Id {get;} SomeEnum Type {get;} } and it's implementation HeapObject: class HeapObject : IHeapObject { public str
  • c# - Style for creating IEnumerable unions - Software Engineering Stack . . .
    var list1and2 = Enumerable Union(list1, list2); var reallyBigList = Enumerable Union(list1and2, list2); Is there a clean way of setting up these more complex unions? Would an extension like Enumerable Union(params IEnumerable<T> collections) (used like var reallyBigList = Enumerable Union(list1, list2, list3)) be better?
