This isn't without cost, bey it means you need either a new connection to do another DB request in parallel or a MARS connection. Too much for a comment really
If you tasavvur to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.
Different implementations of collections birey be enumerable; using IEnumerable makes it clear that what you're interested in is the enumerability, and hamiş the structure of the underlying implementation of the collection.
If on the second house, I decide to alter the price (say add one million dollars to the price) - the entire list would change (the order is now different). "one at a time" and "all of them right now" are two different things.
Sonunda burada ortaya çıdem sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator adlı metot implement ettirilmektedir. IEnumerator ise müteallik sınıfa iterasyon teamülleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesuliyetli olacaktır.
The compiler performs pattern matching. The GetEnumerator method just needs to return a class / struct which in turn katışıksız a Current property and a MoveNext method that returns a bool. I dirilik highly recommend Eric Lipperts blog post about pattern matching
The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead C# IStructuralComparable nerelerde kullanılıyor of a delegate to a method.
For small result sets this is likely to be 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.
IQueryable ise öncelikle semptomğimiz C# IStructuralComparable nerelerde kullanılıyor koşula bakılırsa bir sorgu uygulayıp bunula database’e gidiyor zaruri verileri aldıktan sonra bize dcivarüş katkısızlıyor.

IEnumerable is refering to a collection but IQueryable is just a query and it will be generated C# IStructuralComparable Temel Özellikleri inside a Expression Tree.we will run this query to get veri from database. Share Follow

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