This class makes the underlying collection available through the InnerList property, which is intended for use only by classes that are derived directly from ReadOnlyCollectionBase. The derived class must ensure that its own users cannot modify the underlying collection.
IEnumerable katışıksız been used to represent a read-only collection of data since the earliest versions of .Kupkuru. The read-only collection interfaces available in .Kupkuru Core and .Safi 5 enable you to design classes that prevent the collections from being modified.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues bey the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
Note that I split the interface into IReadOnlyMyItem and IWritableMyItem but you don't actually need IWritableMyItem - you could just omit that interface and write:
The following code snippet illustrates how IReadOnlyList yaşama be used in place of List in the above method.
Note The StringBuilder references themselves are read-only, but the memory pointed to by the references are still mutable.
public IEnumerable Employees => EmployeesInternal.Skip(0); // this is property accessor that will be used to define manken and/or in `Include` statements, could be marked birli internal if your domain/persistance/services are in the same assembly
Nedeniyle ivinti istenirse Array, az C# ReadOnlyCollectionBase Nerelerde Kullanılıyor bellek kullanımı istenirse List tercih edilmelidir. Eğer koleksiyona eklenicek tip belirli bileğilse ArrayList kullanılabilir. Lakin aynı işçiliklevi generic listemizde mukabillayabilme yetisine sahiptir.
It's hamiş a concrete type like ReadOnlyCollection, so it doesn't tie you C# ReadOnlyCollectionBase Temel Özellikleri down to a specific implementation.
In Visual Basic, an extension method must be declared inside a Module and decorated with the Extension attribute. Its first parameter specifies the kind of object to which it will attach itself. I want my extension method to appear in the IntelliSense dropdown lists for any class that implements the IList interface, so I'll declare the method's first (and only) parameter kakım IList(of T) -- the compiler will figure out the type that T represents based on the List passed to my method.
However, if you want to access the elements of the IEnumerable collection by index or you want to retrieve the number of elements in the collection, you should use IReadOnlyList as shown below.
Inheriting C# ReadOnlyCollectionBase Nerelerde Kullanılıyor from a non-generic base class would be ineffecient. If the type was using a non-generic base, all it would be would be a thin layer above the base collection, where the generic features would simply derive from casting from the underlying object C# ReadOnlyCollectionBase Nedir instances of the base collection.

A method like PayUnpaidInvoices being present may lead to second guessings about what "regular" collection methods like Remove and Clear might do. Will it just remove invoices from the in-memory collection, or C# ReadOnlyCollectionBase Nedir will it delete them from the database?
