In C#, access specifiers (also called access modifiers ) control the visibility and accessibility of classes, methods, properties, and other members. They define who can access a class or member . Here’s a clear explanation for your forum answer: 1. public Accessible from anywhere in the project or other assemblies. public class MyClass { public int MyValue; // accessible anywhere } Use it when you want the member to be visible everywhere. 2. private Accessible only within the containing class . class MyClass { private int myValue; // accessible only inside MyClass } Default for class members. Use for encapsulation. 3. protected Accessible within the containing class and derived classes (inheritance). class BaseClass { protected int myValue; } class DerivedClass : BaseClass { void Test() { myValue = 10; // OK } } 4. internal Accessible only within the same assembly/project . internal class MyClass { internal int myValue; } Useful for library code that should not be exposed outside the project. 5. protected internal Accessible from derived classes or within the same assembly . protected internal int myValue; Combines protected + internal . 6. private protected (C# 7.2+) Accessible only within the containing class or derived classes in the same assembly . private protected int myValue; More restrictive than protected internal .

In C#, access specifiers (or access modifiers ) decide who can use a class, method, or variable. Here are the main ones: public → Anyone can access it. private → Only inside the same class. protected → Inside the same class + child (derived) classes. internal → Only inside the same project/assembly. protected internal → Inside the same project + child classes (even if child is in another project). private protected → Inside the same class + child classes, but only if they’re in the same project.
