Average(IEnumerable, Func) Computes the average of a sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.
IEnumerable özgü been used to represent a read-only collection of veri since the earliest versions of .Kemiksiz. The read-only collection interfaces available in .NET Core and .NET 5 enable you to design classes that prevent the collections from being modified.
Average(IEnumerable, Func) Computes the average of a sequence of Single values that are obtained by invoking a transform function on each element of the input sequence.
Kakım the last point states, you shouldn't avoid ReadOnlyCollection like you were suggesting. It is a very useful type to use for public members to inform the consumer of the limitations of the collection they are accessing.
Imagine we have existing biçim with Organization => Employees already grup up. To apply this technique, we need to change Organization biçim a bit:
You want to use the yield keyword. You loop through the IEnumerable list and return the results with yeild. This allows the consumer to use the for each without modifying the collection.
public IEnumerable Employees => EmployeesInternal.Skip(0); // this is property accessor that will be used to define örnek and/or in `Include` statements, could be marked kakım internal if your domain/persistance/services are in the C# ReadOnlyCollectionBase Kullanımı same assembly
protected virtual ICollection EmployeesInternal get; private kaş; = new List(); // this will expose collection contents to public, seemingly unneccessary `Skip` statement will prevent casting back to Collection
C# Queue klası yararlanmaı olabildiğince basittir ve çeşitli adımları yürekerir. Bu adımları yakınlarında bir şekilde uyma ederek, Queue dershaneını müsmir C# ReadOnlyCollectionBase Nedir bir şekilde kullanabilirsiniz. İşte temel adımlar ve detayları:
Movie about a planet where seeds must be harvested just right in order to liberate a valuable crystal within
ICollection is such abstraction and you could say that C# ReadOnlyCollectionBase Temel Özellikleri ICollection does hamiş have an exact C# ReadOnlyCollectionBase Temel Özellikleri corresponding peer in the generic world; IEnumerable is the closest.
Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads güç C# ReadOnlyCollectionBase Kullanımı still modify the collection, which causes the enumerator to throw an exception.
When you pass around collections instead of writing an object biçim, entire classes of refactorings will never occur to you.
