Class is a blue print. It is a collection of methods and member functions. In Object oriented programming every line of code should be in class. It is a reference type. Mandatory to use the "new" keyword for creating object. Class can contain variable.

Static method is a method which can be called without any reference or object because memory for a static method is created in RAM when program is executed.Static method is a method which is created using keyword "static".ExampleAddition of two numbers.

Abstract method is a method which is created using "abstract"keyword.It doesn't have any implementation or body.It will have only signature.Semicolon is required at the end of signature.It is implemented in the class which inherits it.Syntax for creating.

It is one of the method that contains both arguments and return type.Examplepublic long add(int a,int b){return a+b.

It is one of the method that doesn't have any arguments/parameters. It contains only return type.Examplepublic int add(){Console.WriteLine("addition");return 1;}A method can return value to anything which is capable of holding that value.Exampleint.

It is one type of method and consists of arguments/parameters.Examplepublic long add(int a,int b){Console.WriteLine(a+b);}ExplanationIn the above example the add() can take two values of int type as inputs and doesn't return any type because long data.

Simple method is a method that doesn't have any arguments and return type.SyntaxAccess specifier return type methodname( )Examplepublic void add(){Console.WriteLine("addition").

Method is a piece of code which is used to perform a particular task. A Method can be either no value returning or value returning. If it was a no value returning we will use void as return type for that method.  If it was a value returning we.

OOPS stands for Object Oriented Programming Structure.It was a new approach in programming introduced in 1970's when a suffered problems with procedural programming languages like lack of security and reusability.Object Oriented approach provides us.

C# provides a jump statements that allow you to jump immediately to another line in a program.They are:1. goto2. break3. continue goto It allows you to jump directly to another specified line in the program indicated by a label which.

Do while loop executes a set of statements inside it atleast once and repeated till the condition is met.SyntaxDo{<statements>} while(condition); C#.NET DoWhile Example programProgram using System; namespace DoWhileLoop {    .

While loop is used to execute a set of statements till the condition is met. It doesn’t have initialization and increment or decrement operators as part of its syntax.SyntaxWhile(condition){<Statements>}C#.NET While loop programProgram using.

foreach loop is a special loop used for collections and arrays. It is repeated based on the number of elements in a collection. It automatically takes one by one element from a collection and it is repeated till the last element is printed. Syntax.

C#.NET for loop is used to execute a code repeatedly until the condition is true. For loops are appropriate when you know exactly how many times you want to perform the statements within the loop. Normally, for loop statements execute from the opening.

C#.NET provides four different loops that allows you to execute a block of code repeatedly until a certain condition is met. Those are as follows 1) for loop 2) while loop 3) dowhile loop 4) foreach lo.

The switch statement which allows you to compare an expression with a number of different values. Syntax of C#.NET Switch statement switch(variable) { case value1: statements; break; case value2: statements; break; ------------------- ------------------- ------------------- default: statements; break; .
