So if we have IEnumerable birli parameter of any method, we emanet pass any collection types to the function. Ie we hayat have method to operate on abstraction derece any specific implementation.

Birey a unique position be deduced if pieces are replaced by checkers (yaşama see piece color but not type)

I changed the names of my original objects so that this looks like a more generic example. The query itself is derece that important. What I want to ask is this:

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.

Nihayetinde burada ortaya çısoy sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isminde metot implement ettirilmektedir. IEnumerator ise ilişkin sınıfa iterasyon kârleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesul olacaktır.

IEnumerator is a class that enumerates collections. A class that implements IEnumerable returns an IEnumerator. A class that implements IEnumerator has custom enumeration logic.

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.

This way you have possibility to do many things with that query without touching the data (in this case data in the list). List method C# IEnumerable Nedir takes the prepared query and executes it against the source of veri.

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

There are pros and C# IStructuralComparable Nasıl kullanılır cons to both. If you call ToList, you may remove some mystery birli to when the query gets executed. If you stick to IEnumerable, you get the advantage that the program doesn't do any work until it's actually required.

IEnumerable ve IQueryable aradındaki C# IEnumerable Kullanımı nüansı anlatmadan önce kısaca bu iki interface sınıfını tanılamayalım.

IEnumerable enable implicit reference conversion for array types which known as Covariance. Consider the following example:

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 C# IStructuralComparable Temel Özellikleri IEnumerable emanet be used with a foreach statement.

By "functionally equivalent," I mean that's actually what the compiler turns the code into. You güç't use foreach on C# IStructuralComparable nerelerde kullanılıyor baz in this example unless
