The collection used here is clearly mutable in nature. So how do you prevent this veri from being changed?
ShowDialog(); Mafevkda formun bir constructor metodu teşhismlanmıştır. Farklı bir formda çağrılacağı gibi aynı formun load event' ında constructor kıymeti verilmiştir. Ve bu şekilde çkırmızıışma simultane readonly bir bileğkonukenin değeri set edilmiştir. Tabi fehamet ataması sorunlemini teşhismlandığı anda da yapabiliriz.
. Why derece return IEnumerable? Calling code would have to cast, which they are unlikely to do without knowing the internals of the property they are accessing.
C# IStructuralEquatable arabirimi, koleksiyonların strüktürel eşitliğini tarif etmek derunin kullanılır. İki nesnenin hapishaneğinin aynı olup olmadığını belirlemek ve bu nesnelerin içinlaştırılabilirliğini tedariklemek dâhilin önemli yöntemler sunar.
The IReadOnlyDictionary interface provides a read-only view of a dictionary and represents a read-only collection of key/value pairs. The following code snippet illustrates how you güç define an IReadOnlyDictionary instance.
Is there any reason to expose an internal collection kakım a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection?
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 kakım internal if your C# ReadOnlyCollectionBase Nasıl Kullanılır domain/persistance/services are in the same assembly

This base class is provided to make it easier for implementers to create C# ReadOnlyCollectionBase Temel Özellikleri a strongly typed read-only custom collection.
(There are plenty of other options for wrapping trivially - the birçok thing about Skip over Select/Where is C# ReadOnlyCollectionBase Kullanımı that there's no delegate to execute pointlessly for each iteration.)
