Access Modifiers (C# Programming Guide)
In this articleAll types and type members have an accessibility level. The accessibility level controls whether they can be used from other code in your assembly or other assemblies. An assembly is a .dll or .exe created by compiling one or more .cs files in a single compilation. Use the following access modifiers to specify the accessibility of a type or member when you declare it:
Summary table
The following examples demonstrate how to specify access modifiers on a type and member:
Not all access modifiers are valid for all types or members in all contexts. In some cases, the accessibility of a type member is constrained by the accessibility of its containing type. Class, record, and struct accessibilityClasses, records, and structs declared directly within a namespace (in other words,
that aren't nested within other classes or structs) can be either Struct members, including nested classes and structs, can be declared Derived classes and derived records can't have greater accessibility than their base types. You can't declare a public class You can enable specific other assemblies to access your internal types by using the Class, record, and struct member accessibilityClass and record members (including nested classes, records and structs) can be declared with any of the six types of access. Struct members can't be declared as Normally, the accessibility of a member isn't greater than the accessibility of the type that contains it. However, a The type of any member field, property, or event must be at least as accessible as the member itself. Similarly, the return type and the parameter types
of any method, indexer, or delegate must be at least as accessible as the member itself. For example, you can't have a User-defined operators must always be declared as Finalizers can't have accessibility modifiers. To set the access level for a

FeedbackSubmit and view feedback for Which access modifier is accessible within the same class?Private: The private access modifier is specified using the keyword private. The methods or data members declared as private are accessible only within the class in which they are declared. Any other class of the same package will not be able to access these members.
Which access modifier is accessing in any class or package?Public Access Modifier - Public
A class, method, constructor, interface, etc. declared public can be accessed from any other class.
Which access modifier is accessible within package and outside the package but through inheritance only?Protected: We can access the protected modifier within the same package and also from outside the package with the help of the child class. If we do not make the child class, we cannot access it from outside the package. So inheritance is a must for accessing it from outside the package.
Which method is accessible only in the classes in which it is defined?Private Access Modifier
The methods and fields that are declared as private are not accessible outside the class. They are accessible only within the class which has these private entities as its members.
