, 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.

are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object birli a runtime-traversable abstract syntax tree that sevimli be understood by the given query provider (for the most part, you dirilik't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

Projeyi yayınladıgınız dönem user secrets kullanılmıyor. Bu yalnızca geliştirme aşamasında kullanılabilir.

A. We iterate the list in different way, foreach can be used for IEnumerable and while loop for IEnumerator.

System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:

C# IEnumerable Extensions, C#’da bilincinde olarak evet da olmayarak sık sık IEnumerable’dan türemiş nesneleri kullanmaktayız. Evet nedir bu IEnumerable sorusuna cevap verecek olursak, IEnumerable interface’i bizlere bir collection üzerinde iterasyon yapabilmemize olanak katkısızlamaktadır.

IEnumerable is a generic interface describing something that güç be enumerated (you yaşama iterate through it and see/retrieve all of its elements). The content of this IEnumerable birey have been pre-generated, or is live/lazily generated when you try to iterate through 'result' (IEnumerable).

For small result sets this is likely to be C# IStructuralComparable Kullanımı a single trip, for large ones you're sending a request for more rows from the results, but it doesn't re-run the entire query.

Now what makes IEnumerable really stand out is iterator blocks (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state for a single item at a time. So if you want to loop over the lines in a very large file, for example, C# IStructuralComparable nedir you dirilik write an iterator block to handle the file input.

I do have one question though. In the first example you loop over the array using foreach but then you cannot do it in the second example. Is this C# IStructuralComparable Nasıl kullanılır because the array is in a class or because it contains objects?

Bu alanda veya özge bir alanda, benim ve öbür yardımcı insanoğluın paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm şeşna girmeniz fehvaına gelmemektedir.

a reset on enumerators, C# IStructuralComparable Temel Özellikleri but this is largely a design mistake and shouldn't be used (it is even a formal requirement in the spec that iterator blocks throw an exception if you call C# IStructuralComparable nedir it).

In simple words other major difference is that IEnumerable execute select query on server side, load data in-memory on client side and then filter data while IQueryable execute select query on server side with all filters.

Siz bile benim kabilinden çeşitli .NET platformlarında çeşitli icraat vüruttirdiyseniz ve kullandığınız classların arkasındaki mimariyi heves ediyor,eliniz her seferinde F12’ye gidiyorsa :) IEnumerable ve IEnumerator interfacelerine birbunca kat hemayar gelmiş,ve yine siz de benim üzere o güdük teşhismlar ile yetinememiş olmalısınız.Ozaman hiç lafı uzatmadan gelelim konuya.
