En iyi Tarafı C# IEnumerable Temel Özellikleri

, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more data than is actually needed, and we waste cycles doing the filtering in the client.

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

So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.

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.

This will create a new list element for each element in memory, enumerating the IEnumerable and is thus less performant if you only enumerate once - but safer and sometimes the List methods are handy (for instance in random access).

I noticed that if I use "Distinct", the "inner" contains 6 items (this is incorrect bey only 2 are Distinct), but the "outer" does contain the correct values. Again, probably the delegated methods determine this but this is a bit more than I know about IEnumerable.

// but this throws an exception, because the C# IStructuralComparable Kullanımı pointer or link to the // database namely the DbContext called MyEntities no longer exists.

It is a best practice to implement IEnumerable and IEnumerator on your collection classes to enable the foreach (For C# IStructuralComparable nedir Each in Visual Basic) syntax, however implementing IEnumerable is derece required. If your collection does hamiş implement C# IStructuralComparable nerelerde kullanılıyor IEnumerable, you must still follow the iterator pattern to support this syntax by providing a GetEnumerator C# IEnumerable Nedir method that returns an interface, class or struct.

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 birey be used with a foreach statement.

Eğer ki siz “var” almak istiyorsanız GetEnumerator metodunun aptal dhuzurüş tipini adidaki üzere generic IEnumerator olarak C# IStructuralComparable nedir tanılamamlamanız gerekmektedir.
