C# Programming

Explain the concept of inheritance in object-oriented programming in C#.

• Inheritance in C# allows a class to inherit properties and behaviors from another class, promoting code reusability and creating a hierarchy of classes.

• Inheritance in C# is used to create new instances of a class.

• Inheritance in C# is not supported in object-oriented programming.

• Inheritance in C# only allows a class to inherit properties but not behaviors.

What is the difference between value types and reference types in C#?

• Value types and reference types are the same

• Reference types store their actual value

• The difference is that value types store their actual value, while reference types store a reference to the actual value.

• Value types store a reference to the actual value

Explain the concept of polymorphism in object-oriented programming in C#.

• Polymorphism in C# allows a class to inherit properties and behaviors from another class, promoting code reusability and creating a hierarchy of classes.

• Polymorphism in C# is used to create new instances of a class.

• Polymorphism in C# is not supported in object-oriented programming.

• Polymorphism in C# allows a class to have multiple forms or behaviors based on its inheritance.

What is the purpose of interfaces in C#?

• Interfaces in C# are used to define a set of methods that a class must implement.

• Interfaces in C# are used to create new instances of a class.

• Interfaces in C# are not supported in object-oriented programming.

• Interfaces in C# only allow a class to inherit properties but not behaviors.

Explain the concept of encapsulation in C#.

• Encapsulation in C# allows a class to inherit properties and behaviors from another class, promoting code reusability and creating a hierarchy of classes.

• Encapsulation in C# is used to create new instances of a class.

• Encapsulation in C# is not supported in object-oriented programming.

• Encapsulation in C# is the concept of wrapping data and methods that work on the data within a single unit.

What is the use of abstract classes in C#?

• Abstract classes in C# are used to define a set of methods that a class must implement.

• Abstract classes in C# are used to create new instances of a class.

• Abstract classes in C# are not supported in object-oriented programming.

• Abstract classes in C# only allow a class to inherit properties but not behaviors.

Explain the concept of method overloading in C#.

• Method overloading in C# allows a class to inherit properties and behaviors from another class, promoting code reusability and creating a hierarchy of classes.

• Method overloading in C# is used to create new instances of a class.

• Method overloading in C# is not supported in object-oriented programming.

• Method overloading in C# allows a class to have multiple forms or behaviors based on its inheritance.

What is the purpose of using 'using' statement in C#?

• The 'using' statement in C# is used to define a set of methods that a class must implement.

• The 'using' statement in C# is used to create new instances of a class.

• The 'using' statement in C# is used to automatically dispose of unmanaged resources.

• The 'using' statement in C# only allows a class to inherit properties but not behaviors.

Explain the concept of exception handling in C#.

• Exception handling in C# allows a class to inherit properties and behaviors from another class, promoting code reusability and creating a hierarchy of classes.

• Exception handling in C# is used to create new instances of a class.

• Exception handling in C# is not supported in object-oriented programming.

• Exception handling in C# is the process of responding to the occurrence of exceptions during the execution of a program.

What is the purpose of delegates in C#?

• Delegates in C# are used to define a set of methods that a class must implement.

• Delegates in C# are used to create new instances of a class.

• Delegates in C# are used to store references to methods and invoke them.

• Delegates in C# are not supported in object-oriented programming.
