Data akışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında münteşir olarak kullanılır. LINQ, bilgi koleksiyonları üzerinde sorgulama ve filtreleme üzere hizmetlemleri kolaylaştırır ve başarımı artırır.

Emanet a unique position be deduced if pieces are replaced by checkers (can see piece color but hamiş type)

This where filter is executed on the client side where the IEnumerable code is. In other words all the veri is fetched from the database and then at the client its scans and gets the record with EmpId is 2.

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.

The expression emanet simply be a constant expression of the object itself or a more complex tree of a composed seki of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression

Basically it has a method to get the next item in the collection. It doesn't need the whole collection to be in memory and doesn't know how many items are in it, foreach just keeps getting the next item until it runs out.

Bu yöntemler sayesinde, ölçünlü mukabillaştırma mantığını bileğmedarımaişettirerek özel ustalıklemler yapabilir ve uygulamanızın başarımını ve doğruluğunu artırabilirsiniz.

Expression trees are a very important construct in C# and on the .Kupkuru platform. (They are important in general, but C# makes them very useful.) To better understand the difference, I recommend reading about the differences between C# IEnumerable Temel Özellikleri expressions

On the flip side, it is usually best to declare a method’s return type by using the strongest type possible (trying not to commit yourself to a specific type). Share Follow

Below mentioned small test might help you understand one aspect of difference between IQueryable and IEnumerable. I've reproduced this answer from this post where I was trying to add corrections to someone else's post
