Data akışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında yaygın olarak kullanılır. LINQ, done koleksiyonları üzerinde sorgulama ve filtreleme kabilinden meselelemleri kolaylaştırır ve performansı fazlalıkrır.
Koleksiyonlar Ortada Gezinmeyi Sağlamlar: IEnumerable, koleksiyonlar ortada kolay gezinmenizi katkısızlar. GetEnumerator metodu ile koleksiyonun her bir elemanına erişebilir ve bu elemanlar üzerinde muamelat yapabilirsiniz.
The second example returns an IEnumerable that contains all the information needed to run the query later on.
Now List implements IEnumerable, but represents the entire collection in memory. If you have an IEnumerable and you call .ToList() you create a new list with the contents of the enumeration in memory.
System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:
IEnumerator is a class that enumerates collections. A class that implements IEnumerable returns an IEnumerator. A class that implements IEnumerator saf custom enumeration logic.
So the difference between IQueryable and IEnumerable is about where the filter logic is executed. One executes on the client side and the other C# IEnumerable Nedir executes on the database.
You don't have to open a book and learn how to traverse the tree - but simply use the foreach statement on that object and you're done.)
Where the execution will be performed out-of-process, the logic of the query özgü C# IEnumerable Kullanımı to be represented in veri such that the LINQ provider gönül convert it C# IEnumerable Temel Özellikleri into the appropriate form for the out-of-memory execution - whether that's an LDAP query, SQL C# IEnumerable Nerelerde Kullanılıyor or whatever.
There are pros and cons to both. If you call ToList, you may remove some mystery kakım to when the query gets executed. If you stick to IEnumerable, you get the advantage that the program doesn't do any work until it's actually required.
Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the ışıntı and indicating input and output of the Enum?
ümit ederim bu yazgıdan sonrasında iki tipin illet, nerede ve nasıl kullanılması gerektiğine dayalı yeterli bilgiye ehil olmuşsunuzdur.
Upgrade to Microsoft Edge to take advantage of the latest C# IEnumerable Nasıl Kullanılır features, security updates, and technical support.
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
