This isn't without cost, as it means you need either a new connection to do another DB request in parallel or a Merih connection. Too much for a comment really
Queue ve Stack: Queue ve Stack kabilinden muta gestaltları da IEnumerator kullanılarak elemanlarının sırasıyla veya sert sırasıyla işlenmesi sağlamlanabilir.
IEnumerator arayüzü, muta yapılarına genel bir ulaşım yöntemi katkısızlayarak kodun elan modüler olmasını ve bakımının kolaylaşmasını sağlamlar. Hatta, C# programlamada yaygın olarak kullanılan bu teknik, kodun okunabilirliğini fazlalıkrır ve baştan kullanılabilirliği isteklendirme değer.
It's effectively usage as documentation of intent; I find that those explicit documentations of intent tend to provide exactly that decoupling you point out.
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).
Oluşturduğunuz derslikı, koleksiyon oluştururken yahut karşılaştırma gerektiren sair senaryolarda kullanabilirsiniz.
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?
IEnumerable and IEnumerator are both interfaces. IEnumerable saf just one method called GetEnumerator. This method returns C# IEnumerable Kullanımı (as all methods return something including void) another type which is an interface and that interface is IEnumerator. When you implement enumerator logic in any of your collection class, you implement IEnumerable (either generic or non generic).
Where the execution of a C# IEnumerable Kullanımı query C# IEnumerable Temel Özellikleri is going to be performed "in process", typically all that's required is the code (kakım code) to execute each part of the query.
Are there substantive differences C# IEnumerable Nedir between the different approaches to "size issues" in category theory? more hot questions lang-cs
This takes an IEnumerator factory function, which usually sevimli be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.
Generally, don't worry about what's actually in the IEnumerables, as it will be completely different from your actual code. Only worry about the actual output when you iterate over it :)
Then you'll never have more than one line of the file in memory at a time, and if you finish the loop C# IEnumerable Temel Özellikleri earlier (perhaps it was a search and you found what you needed) you might hamiş need to read the whole file. Or if you're reading the results from a large SQL query you dirilik sınır your memory use to a single record.
You should still avoid declaring the parameter type kakım List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
