Can we have protected constructor in C#?
Can we have protected constructor in C#?
The only way to cause a protected constructor to be called is to derive from the class and have the derived class delegate to it or to have a static method create it or some other internal method.
What is protected internal in C#?
The protected internal keyword combination is a member access modifier. A protected internal member is accessible from the current assembly or from types that are derived from the containing class. For a comparison of protected internal with the other access modifiers, see Accessibility Levels.
What is the scope of protected internal?
What is scope of a Protected Internal member variable of a C# class? The protected internal access specifier allows a class to hide its member variables and member functions from other class objects and functions, except a child class within the same application.
What happens when constructor is declared as protected?
A protected constructor means that only derived members can construct instances of the class (and derived instances) using that constructor. This sounds a bit chicken-and-egg, but is sometimes useful when implementing class factories.
Can we have private and public constructor in same class C#?
We can’t create public and private constructors simultaneously in a class, both without parameters. We can’t instantiate the class with a private constructor. If we want to create an object of a class with private constructor then, we need to have public constructor along with it.
What is difference between protected and protected internal?
protected – Protected members can be accessed only from the child classes. internal – It can be accessed only within the same assembly. protected internal – It can be accessed within the same assembly as well as in derived class.
Can we declare class as protected in C#?
Note that you cannot declare any outer class as private, protected (or protected internal) in c# since the access modifier for outer level classes defines their visibility in relation to other assemblies.
What is the difference between private and internal in C#?
Private: – Private members are only accessible within the own type (Own class). Internal: – Internal member are accessible only within the assembly by inheritance (its derived type) or by instance of class.
Can a class be private in C#?
Class members, including nested classes and structs, can be public, protected internal, protected, internal, or private. The access level for class members and struct members, including nested classes and structs, is private by default. Private nested types are not accessible from outside the containing type.
Can we have protected constructor?
Modifiers public, protected and, private are allowed with constructors. We can use a private constructor in a Java while creating a singleton class.
