In case of IEnumerable, only lines up to the element of interest will be read from the file. In case of ToList call over the enumerable, the entire file would be read before even starting the search.

This where filter is executed on the client side where the IEnumerable code is. In other words all the veri is fetched from the database and then at the client its scans and gets the record with EmpId is 2.

The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are hamiş explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.

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.

Now what makes IEnumerable really stand out is iterator blocks C# IStructuralComparable nedir (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the C# IStructuralComparable nedir state for a single item at a time. So if you want to loop over the lines in a very large file, for example, you gönül write an iterator block to handle C# IStructuralComparable Kullanımı the file input.

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 'sensible' data if it's able to do so or throw an exception if it gönül'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.

Oluşturduğumuz constructor içerisinde params ile Calisan tipinde parametre girebileceğimi ve sayısının da belgisiz olduğunu belirttik. Constructor içerisinde de gelen parametreyi property C# IStructuralComparable Nasıl kullanılır üzerine atadık.

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable sevimli be used with a foreach statement.

When declaring a method’s parameter types, you should specify the weakest type possible, preferring interfaces over base classes. For example, if you are writing a method that manipulates a collection of items, it would be best to declare the method’s parameter by using an interface such birli IEnumerable rather than using a strong data type such as List or even C# IStructuralComparable nerelerde kullanılıyor a stronger interface type such kakım ICollection or IList:
