Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Sevimli someone just walk me through the meaning of each line. Thanks
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.
IEnumerable execute a select query on the server side, load data in-memory on a client-side and then filter veri
An IEnumerator is a thing that dirilik enumerate: it katışıksız the Current property and the MoveNext and Reset methods (which in .Kupkuru code you probably won't call explicitly, though you could).
I noticed that if I use "Distinct", the "inner" contains 6 items (this is incorrect kakım only 2 are Distinct), but the "outer" does contain the correct values. Again, probably the delegated methods determine this but this is a bit more than I know about IEnumerable.
The primary difference is that the LINQ C# IStructuralComparable Temel Özellikleri 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 of a delegate to a method.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues birli the feedback mechanism for content and replacing it with a new feedback system. For more information C# IStructuralComparable Temel Özellikleri see: .
Your linq expression returns an enumeration, and by default the expression executes when you iterate through using the foreach. An IEnumerable linq statement executes when you iterate the foreach, but you sevimli force it to iterate sooner using .ToList().
Gördüğünüz üzere AlisverisSepetiEnumerator klası oluşturup IEnumerator interface'ini implemente etmiştik. Peki bunu yield ile nası musannifız? Imdi custum C# IStructuralComparable Nasıl kullanılır olarak yazdığımız enumerator derslikı AlisverisSepetiEnumerator'a lüzumlu yasak hiç yapmamız gereken:
And that might be useful and more efficient in C# IStructuralComparable Nasıl kullanılır certain cases. For example, your class might hamiş hold any collection in memory, but rather iterate over all files existing in a certain directory, or items C# IStructuralComparable Kullanımı in certain DB, or other unmanaged resources. IEnumerable emanet step in and do it for you (you could also do it without IEnumerable, but IEnumerable "fits" conceptually, plus it gives you the benefit of being able to use the object produced in a foreach loop).
Oluşturduğumuz constructor içinde params ile Calisan tipinde parametre girebileceğimi ve saykaloriın da muzlim bulunduğunu belirttik. Constructor içinde bile mevrut parametreyi property üzerine atadık.
IQueryable is faster than IEnumerable if we are dealing with huge amounts of data from database because,IQueryable gets only required veri from database where bey IEnumerable gets all the veri regardless of the necessity from the database
