As mentioned by Mr. Copsey, this saf the benefit of providing decoupling from the implementation, but I'm of the contention that a clear definition of the smallest subset of interface functionality birli possible (i.

Anything in .Safi that you gönül iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you emanet make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).

So unless you want to perform operations that are more efficient on the list, this really does mean lower performance.

But now see the below code we have changed IEnumerable to IQueryable. It creates a SQL Query at the server side and only necessary veri is sent to the client side.

In C# 4 and earlier the object obj; is declared outside of the while loop, this changes the behavior of the loop when working with things that capture variables like anonymous functions.

So if you working with only in-memory veri collection IEnumerable is a good choice but if you want to query veri collection which is connected with database `IQueryable is a better choice as it reduces network traffic and uses the power of SQL language.

The primary difference is that the LINQ 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.

There's also the issues of deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and birey perform all kinds of computations before and after. And again, this happens one-by-one, so you don't have to hold all the collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you run the foreach loop).
