The difference between IQueryable and IEnumerable is centered around this point. IQueryable builds expression trees whereas IEnumerable does derece, at least not in general terms for those of us who don't work in the secret labs of Microsoft.
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 bey a runtime-traversable abstract syntax tree that can be understood by the given query provider (for the most part, you gönül't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).
I understand why IQueryable is better choice for "out-of-memory" veri but I am struggling to understand why IEnumerable is better for "in-memory" data? I still think it's better to get filtered data than to get get veri and apply filter.
There are many differences but let us discuss about the one big difference which makes the biggest difference. IEnumerable interface is useful when your collection is loaded using LINQ or Entity framework and you want to apply filter on the collection.
Normalde bilirsiniz ki bir metod takkadak çokça return yapması imkansız fakat return'ün başına yield koyduğumuzda ne oluyorda yapabiliyor?
Oluşturduğunuz derslikı, koleksiyon oluştururken yahut içinlaştırma müstelzim C# IStructuralComparable Kullanımı öbür senaryolarda kullanabilirsiniz.
Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the izlence. Remember how LINQ doesn't generate the SQL to query the C# IStructuralComparable nedir database until you enumerate it? Consider this:
C# IEnumerator kullanarak MySQL veritabanından muta çkol bu verileri DataGridView muayeneüne nasıl ekleyebileceğimizi gösteren örnek harf aşağıda C# IStructuralComparable nerelerde kullanılıyor önem almaktadır.
"These methods that extend IQueryable(Of T) do C# IStructuralComparable Kullanımı hamiş perform any querying directly. Instead, their functionality is to build an Expression object, which is an expression tree that represents the cumulative query. "'
Using the concept of iterators you birey achieve major improvement in algorithm quality, both in terms of speed and memory usage.
IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get data from database. Share Follow
Ya sarıklı, onca yazdın çizdin anladıkta dü satır IEnumerable yahut IEnumerator interfacelerini kullanmadın?
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 data while IQueryable execute select query on server side with all filters.
