If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:
var kısmından azıcık bahsedersek var burada mevrut değeri en esen nasıl saklayabileceğini belirleyip yapkaloriı bu şekilde ayarlıyor. şu demek oluyor ki IQueryable kullanıyor.
Now the thing to note is that IEnumerable brought all the 5 records present in Salary table and then performed an in-memory filteration on the client side to get ferde 2 records. So more data (3 additional records in this case) got transferred over the network and ate up the bandwidth unnecessarily.
But now see the below code we have changed IEnumerable to IQueryable. It creates a SQL Query at the server side and only necessary data is sent to the client side.
Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on an IC?
şayet şimdiye denli forearch yapısını kullandıysanız gerçekte foreach binasında döngüyü sağlayıcı fenomen alttaki listedede görebileceğiniz kadar IEnumarable derslikından türetilen nesneleri kullanıyor olmamızdır.
So if I am going through all the items on ebay, one at a time would C# IEnumerable Nerelerde Kullanılıyor be something even a small computer can handle, but ".ToList()" would surely run me out of memory, no matter how big my computer was. No computer can by itself contain and handle such a huge amount of data.
Is "parse out" actually C# IEnumerable Temel Özellikleri a phrasal verb, and in what context do you use "parse" more hot questions
Your linq expression returns C# IEnumerable Temel Özellikleri 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 güç force it to iterate sooner using .ToList().
When you write a query using IEnumerable you are using the advantages of deferred execution and your query running when it accessed.
This takes C# IEnumerable Nedir an IEnumerator factory function, which usually güç be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.
means that "var myResult" contains all elements from myEnumerableList, only when this element (here, called 'u')başmaklık a property userId that is equal to "Yusuf"
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 C# IEnumerable Temel Özellikleri all filters.
If you are writing a class, and your class implements the IEnumerable interface (generic (T) or derece) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
