If an element (method, data member, etc.) with the protected modifier is declared in a class, then the following access restrictions apply: Access from a class instance to the public-member value of the classįigure 5. If a class with a public element is declared as internal, then this element is not accessible from methods of external assemblies.įigure 4. an element is accessible from methods of external assemblies if the element’s class is declared as public.the element is considered available to all methods of the current assembly (Figures 4, 5).When declaring a class member with the public keyword, the following rules apply: Access from internal methods of a class to the private-element ⇑ 5. No access from the inherited class to the private-element value of the classįigure 3. No access from the class instance to the private element valueįigure 2. the element is available to the methods of the class in which it is declared (Figure 3).įigure 1.the element is inaccessible to any inherited classes (Figure 2).the element is inaccessible to any instances (objects) of the class (Figure 1).If an element (method, data member, reference, etc.) with the private access modifier is declared in a class, then the following access rules apply to it: In this case, the private level of access to the class member is assumed. The protected and protected internal access modifiers are used in inheritance.Ī class member can also be declared without a modifier. The C# language offers the following access modifiers: This modifier determines the level of restriction of access to the class member. If an element (method, data member, etc.) is declared in a class, then an access modifier is indicated before it. Access modifiers for an element (member) of a class A class that is only available within the current assembly internal class MyInternalClass A class that is available outside the assembly public class MyPublicClass In this case, the default is the internal modifier for the class.įor example. access_modifier – one of the access modifiers: public or internal.Ī class can be declared without specifying an access modifier.The access modifier for a class is placed before the class keyword: access_modifier class ClassName internal – in this case, the class is considered available only in the assembly where it is defined.It is available to any code in any assembly public – in this case, the class is considered public.If a class is declared in the program, then this class can have one of two access modifiers: modifiers that determine access to a member (element) of the class.
modifiers that define access to the entire class in the assembly and outside of it.When using classes in the C# language, access modifiers are used, which fall into two categories:
