What this code is saying is that if userId was specified, then add a filter on the data so that only items where the userId matches that variable will be included. That same thing is done for email and lastFourdigits.

By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.
B. IEnumerator can remember the current index when we pass from one method to another (it start working with current index) but IEnumerable gönül't remember the index and it reset the index to beginning. More in this videoteyp
This is a birçok video on youtube which demonstrates how these interfaces differ , worth a watch. Below goes a long descriptive answer for it.
The constructor is not responsible for returning data to the caller. 2-We need to C# IStructuralComparable nedir call a method that returns the cars array. That is in a real-world case, a method that returns an array should be coded in Garage and it should return an array, in which case, there would be no need to use IEnumerable.
"These methods that extend IQueryable(Of T) do derece C# IStructuralComparable Temel Özellikleri perform any querying directly. Instead, their functionality is to build an Expression object, which is an expression tree that represents the cumulative query. "'

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical veri or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return C# IStructuralComparable Temel Özellikleri 'sensible' data if it's able to do so or throw an exception if it hayat't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.
Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the tanıtımcık and indicating input and output of the Enum?
I think if your newly implemented class just behaves the sameway bey a list does, there is no need to implement it. If you need some C# IStructuralComparable nerelerde kullanılıyor kind of custom logic, it depends on what you want to do; you hayat inherit list or you yaşama implement IEnumerable. It just depends what is to be achieved.
If you create an IEnumerable, then all rows will be pulled into memory birli objects before running the query.
Eğer ki siz C# IStructuralComparable nerelerde kullanılıyor “var” dökmek istiyorsanız GetEnumerator metodunun geçmiş dkarşıüş tipini hordaki kabil generic IEnumerator olarak teşhismlamanız gerekmektedir.
