4 Answers. 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.
Can we create protected class?
No, we cannot declare a top-level class as private or protected. It can be either public or default (no modifier). If it does not have a modifier, it is supposed to have a default access.
Can a class be declared with protected modifier?
The protected access modifier cannot be applied to class and interfaces. Methods, fields can be declared protected, however methods and fields in a interface cannot be declared protected.
Why is c# protected?
In c#, the protected modifier is used to specify that access is limited to the containing type or types derived from the containing class, so the type or member can only be accessed by code in the same class or in a derived class.
Which modifiers are not allowed in front of class?
Hence only two modifiers ( public and default). If class is public , then it is visible to all classes. If there is no access modifier, then it is visible only for classes within the same package.
Can we call method from constructor?
You shouldn’t: calling instance method in constructor is dangerous because the object is not yet fully initialized (this applies mainly to methods than can be overridden). Also complex processing in constructor is known to have a negative impact on testability.
Can a constructor be private?
Yes. Class can have private constructor. Even abstract class can have private constructor. By making constructor private, we prevent the class from being instantiated as well as subclassing of that class.
Can a class be declared as static?
A class can be declared static only if it is a nested class. It does not require any reference of the outer class. The property of the static class is that it does not allows us to access the non-static members of the outer class.
How can we access protected and private members of a class?
Protected members can only be accessed by descendants of the class, and by code in the same module. Private members can only be accessed by the class they’re declared in, and by code in the same module.
Can we override protected method in C#?
Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.
What is C# protected?
protected: The type or member can be accessed only by code in the same class , or in a class that is derived from that class . internal: The type or member can be accessed by any code in the same assembly, but not from another assembly.
Can we inherit private class in C#?
Private member inheritance: A subclass does not inherit the private members of its parent class. However, if the superclass has properties(get and set methods) for accessing its private fields, then a subclass can inherit.
