1. What does the 'public' access modifier do in C#?
Answer:
Explanation:
The 'public' access modifier in C# makes a member accessible from any other code, regardless of assembly or class.
2. Which access modifier in C# is the most restrictive?
Answer:
Explanation:
The 'private' access modifier is the most restrictive, limiting access to the member within its declaring type only.
3. What is the default access modifier for a class in C#?
Answer:
Explanation:
In C#, the default access modifier for classes is 'internal', meaning the class is accessible only within its own assembly.
4. What does the 'protected' access modifier do in C#?
Answer:
Explanation:
The 'protected' access modifier allows access to a member from within its declaring type and any derived classes.
5. How does the 'internal' access modifier work in C#?
Answer:
Explanation:
The 'internal' access modifier in C# makes a member accessible only within the same assembly.
6. What is the combination of 'protected' and 'internal' called in C#?
Answer:
Explanation:
The 'protected internal' access modifier in C# allows access to a member from within its declaring type, derived types, or any type in the same assembly.
7. What access modifier should be used to allow a member to be accessible only within its declaring type?
Answer:
Explanation:
The 'private' access modifier restricts access to a member exclusively within its declaring type.
8. Which access modifier allows a member to be accessed from derived classes, even in different assemblies?
Answer:
Explanation:
The 'protected internal' access modifier allows a member to be accessible from derived classes, even if they are in different assemblies.
9. What is the default access modifier for a method in C#?
Answer:
Explanation:
In C#, the default access modifier for methods is 'private' unless specified otherwise.
10. Can a 'private' member of a class in C# be accessed from an instance of that class?
Answer:
Explanation:
Private members of a class are accessible from within the class itself but not from outside it, including from instances of the class.
11. What is the effect of the 'protected internal' access modifier on a member in C#?
Answer:
Explanation:
The 'protected internal' access modifier allows a member to be accessed from within its own assembly and from derived classes, even in other assemblies.
12. Which access modifier should be used for members that should be accessible only to derived classes and classes within the same assembly?
Answer:
Explanation:
The 'protected internal' access modifier allows access to a member by derived classes and any class within the same assembly.
13. What does the 'public' access modifier indicate about a member's accessibility?
Answer:
Explanation:
Members declared as 'public' are accessible from any other code, making them the least restrictive in terms of access control.
14. If a member is declared without any access modifier, which access level is applied by default in C#?
Answer:
Explanation:
In C#, if no access modifier is specified for a member, it is implicitly 'private'.
15. What is the purpose of using different access modifiers in C#?
Answer:
Explanation:
Access modifiers in C# are used to control the visibility and accessibility of class members, which is essential for encapsulation and security in object-oriented programming.
