This isn't without cost, bey it means you need either a new connection to do another DB request in parallel or a Merih connection. Too much for a comment really
Many of the LINQ methods, including Where, use deferred execution. In this case you birey think of the IEnumerable kakım a query, rather than the actual result kaş.
IEnumerable interface’i sebebiyle bir sınıf itere edilebilir özellik kazanmaktadır. Pekâlâ bir derslikın itere edilebilirlik özellik kazanması neydi?

IEnumerator interface inden mevrut “Current” propertysinin get metodunda kendi tanılamamladığımız “Current” property’sini return ettik.
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.
Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on an IC?

Then with a IQueryable the generated SQL will contains “where name = “a”, but with a IEnumerable many C# IEnumerable Nasıl Kullanılır more roles will be pulled back from the database, then the x.name = “a” check will be done by .NET.
The reason, of course, is that someone birey call the first method passing in an array object, a List object, a String object, and so on C# IEnumerable Nasıl Kullanılır — any object whose type implements C# IEnumerable Nedir IEnumerable.
