What does the term 'boxing' mean in .net? a) Convert value type to object b) Convert reference type to value type c) Convert the primitive type into a value type d) None of the above Struct's data members are ______ by default. a) Protected b) Public c) Private d) Default Abstract method must contains ___ class a) Abstract class b) Non abstract class c) Both a and b d) Sealed Class
Understand the Problem
The question is asking about specific concepts in .NET programming, particularly regarding boxing, struct members, and abstract methods. It aims to test the understanding of these programming principles.
Answer
a) Convert value type to object, c) Private, a) Abstract class
The term 'boxing' in .NET means converting a value type to an object. Struct's data members are private by default. An abstract method must be contained in an abstract class.
Answer for screen readers
The term 'boxing' in .NET means converting a value type to an object. Struct's data members are private by default. An abstract method must be contained in an abstract class.
More Information
Boxing and unboxing are important for operations where value types need to be referenced as objects. In C#, structs have private fields by default, making them inaccessible to other parts of code unless specified otherwise. Abstract methods must live within abstract classes to ensure implementation by derived classes.
Tips
A common mistake is confusing boxing with unboxing, which is its reverse operation. Also, misunderstanding accessibility defaults in structs can lead to incorrect code.
