C# Interview Questions And Answers
Simply learning this tutorial video has 50 interview questions and all these
questions are divided into three levels beginner, intermediate, and
advanced levels. The C programming language allows for procedural
programming whereas C# programming language provides object-
oriented programming. C# is primarily used in commercial industries and
engineering whereas C# is used for software development and network
development.
The object-oriented programming language or OOP in C# is divided into
four concepts that is encapsulation, abstraction, inheritance and
polymorphism. An object of a class is defined as an instance, technically it
is simply a block of memory that can be stored as variables arrays or
collections. A class is a collection of properties and methods used to
represent a real-time entity.
There are four different types of classes in C# the first is partial class
which states that its members can be divided or shared across multiple
files. The only way to get the class is to inherit it must include at least one
method. The next class is sealed class a sealed class can not be inherited
to access sealed class members. The last difference between a class and a
struct is we can use a garbage collector to manage memory in class.
Namespaces are employed in large code projects like in c sharp the most
common namespace is system. programming polymorphism in
programming means the same method but different implementations it is
classified into two types compile time polymorphism and runtime
polymorphism. exception handling is accomplished using four keywords
try catch finally and through in try.
Catch a program that catches an exception with the help of the exception
handler and finally through throw is when a problem occurs it throws an
exception followed by exception handling. what is a destructor in
seashore destructors are used to clear memory and free resources in c
sharp however this is handled by a garbage collector on its own internally.
System dot collect is used to clean up but it may be necessary to
implement destructors in some classes manually. an abstract class is
denoted by the abstract keyword and only be used as a base class. an
array is a data structure that stores multiple variables of the same data
type. it is a set of variables stored in a single memory location. an array
