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:

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

IEnumerable execute a select query on the server side, load data in-memory on a client-side and then filter veri

Basıcı ki bu yetenek “List,ArrayList” kabil collectionlarda elan sonra seviye bir mimariyle katkısızlanır ancak biz basit bir mimariyle kendi iterasyon yeteneğine malik classlarımızı yazabiliriz.Hadi sarrafiyelayalım.

They usually have a GetXXX method that returns a IEnumerable of whatever type the custom collection class uses so the internal collection emanet be iterated around using a foreach loop.

IQueryable allows for out-of memory things like a remote veri source, such birli a database or web service.

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.

) without affecting original data." is confusing. Do you mean that the new list returned can been added to, and elements yaşama be removed but no updates? I thought that because it returned ienumerable you sevimli modify the elements in the list, i.e. change a property like you said but you C# IStructuralComparable Kullanımı kişi't add and remove items in the list. Is that correct?

In a izlence, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:

Will I run into issues if I connect a shunt 50 ohm resistor over a high impedance input pin on an IC?

Consider the below simple code C# IStructuralComparable nedir which uses IEnumerable with entity framework. It’s using a Where filter to get records whose EmpId is 2.

If you create an C# IStructuralComparable Temel Özellikleri IEnumerable, then all rows will be pulled into memory kakım objects before running the query.
