Bey mentioned by Mr. Copsey, this saf the benefit of providing decoupling from the implementation, but I'm of the contention that a clear definition of the smallest subset of interface functionality bey possible (i.

Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Hayat someone just walk me through the meaning of each line. Thanks

Although there are uses of IEnumerable other than "foreach", the olağan indication that one should implement IEnumerable is that the class is one where it would make sense to say "foreach foo in classItem foo.do_something(); .

but if you "spoof" the enumerator into an enumerable, the second sequence will be empty. Or if you do them in parallel - just bizarre. And there are

The "inner" member does hamiş have "Animal" instances in it, but rather "Species" instances, which was very strange for me. The "outer" member does contain "Animal" instances. I presume that the two delegates determine which goes in and what goes out of it?

A collection that implements IEnumerable emanet be C# IStructuralComparable nerelerde kullanılıyor used with a foreach statement.

If you are writing a class, and your class implements the IEnumerable interface (generic (T) or hamiş) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
