C#

Question 1

access modifier

Answer 1

A keyword, such as private, protected, internal, or public, that restricts access to a type or type member.

Question 2

accessible member

Answer 2

A member that can be accessed by a given type. An accessible member for one type is not necessarily accessible to another type.

Question 3

accessor

Answer 3

A method that sets or retrieves the value of a private data member value that is associated with a property. Read-write properties have get and set accessors. Properties that are read-only have only a get accessor.

Question 4

anonymous method

Answer 4

An anonymous method is a code block that is passed as a parameter to a delegate.

Question 5

base class

Answer 5

A class that is inherited by another ‘derived’ class.

Question 6

call stack

Answer 6

The series of method calls leading from the beginning of the program to the statement currently being executed at run time.

Question 7

class

Answer 7

A data type that describes an object. Classes contain both data, and the methods for acting on the data.

Question 8

constructor

Answer 8

A special method on a class or struct that initializes the objects of that type.

Question 9

delegate

Answer 9

A delegate is a type that references a method. Once a delegate is assigned a method, it behaves exactly like that method.

Question 10

derived class

Answer 10

A class that uses inheritance to gain, augment, or modify the behavior and data of another ‘base’ class.

Question 11

destructor

Answer 11

A special method on a class or struct that prepares the instance for destruction by the system.

Question 12

event

Answer 12

A member of a class or struct that sends notifications of a change.

Question 13

field

Answer 13

A data member of a class or struct that is accessed directly.

Question 14

generics

Answer 14

Generics allow you to define a class and or method that are defined with a type parameter. When client code instantiates the type, it specifies a particular type as an argument.

Question 15

IDE

Answer 15

Integrated Development Environment. The application that provides the unified user interface for the various development tools including the compiler, debugger, code editor, and designers.

Question 16

immutable type

Answer 16

A type whose instance data, fields and properties, does not change after the instance is created. Most value types are immutable.

Question 17

inaccessible member

Answer 17

A member that cannot be accessed by a given type. An inaccessible member for one type is not necessarily inaccessible to another type.

Question 18

inheritance

Answer 18

C# supports inheritance, so a class that derives from another class, known as the base class, inherits the same methods and properties. Inheritance involves base classes and derived classes.

Question 19

interface

Answer 19

A type that contains only the signatures of public methods, events, and delegates. An object that inherits the interface must implement all of the methods and events defined in the interface. Classes or structs may inherit any number of interfaces.

Question 20

iterator

Answer 20

An iterator is a method that enables consumers of a class that contains a collection or array to use foreach, in (C# Reference) to iterate through that collection or array.

Question 21

member

Answer 21

A field, property, method, or event declared on a class or struct.

Question 22

method

Answer 22

A named code block that provides behavior for a class or struct.

Question 23

mutable type

Answer 23

A type whose instance data, fields and properties, can be changed after the instance is created. Most Reference Types are mutable.

Question 24

nested type

Answer 24

A type declared within the declaration of another type.

Question 25

object

Answer 25

An instance of a class. An object exists in memory, and has data and methods that act on the data.

Question 26

property

Answer 26

A data member accessed by means of an accessor.

Question 27

refactoring

Answer 27

Reusing previously entered code. The Visual C# Express Code Editor can intelligently reformat code to, for example, turn a block of highlight code into a method.

Question 28

reference type

Answer 28

A data type. A variable declared as a reference type points to a location where data is stored.

Question 29

static

Answer 29

A class or method declared as static exists without first being instantiated using the keyword new. Main() is a static method.

Question 30

struct

Answer 30

A compound data type that is typically used to contain a few variables that have some logical relationship. Structs can also contain methods and events. Structs do not support inheritance but they do support interfaces. A struct is a value type, while a class is a reference type.

Question 31

value type

Answer 31

A value type is a data type that is allocated on the stack, as opposed to a reference type which is allocated on the heap. The built-In types, including the numeric types as well as the struct type and the nullable type, are all value types. The class type and string type are reference types.
