What is an Array An array is a sequential collection of similar data that can be accessed as per the "index". It is the simplest type of data structure in which the elements get stored in a contiguous memory location. In Array, index starts at zero, so to access the first element of an array "numarray", it should be written as numarray[0]. Example of Array in C# Output:- 10  20  30  40  50 What is an ArrayList The ArrayList is a collection of objects of same or different types. The … [Read more...]

ref (Reference) Parameter "ref" parameter is used to pass the value by reference from actual parameter to formal parameter i.e from callee method to the called method. In C#, a parameter declared with a "ref" modifier is a reference parameter. When you pass parameters by reference, unlike value parameters, a new location is not created for this parameter. Any changes made to the formal parameter will reflect in the actual parameter. Example of ref Parameter As shown in the above program … [Read more...]

The Console class provides basic support for applications that read and write characters to and from the console. The write() method outputs one or more values on the screen without a new line character. This means any subsequent output will be printed in the same line.

Method Overloading Method overloading, also known as Function overloading or Compile time polymorphism, is a concept of having two or more methods with the same name but different signature in the same scope. There are many programming languages that support this feature: Ada, C++, C#, D, and Java. Example of Method Overloading in C# As shown in the above example, the method 'Polygon' is overloaded 3 times with different method signature, i.e the type or the number of parameters are … [Read more...]

Class Class is a user-defined data type that allows the grouping of data members, methods, properties, and events. A class is nothing but a blueprint that defines data and behaviour. Objects are instances of the class. In C#, classes are defined using the 'class' keyword followed by the class name that contains the body of a class surrounded by curly braces. Every class has a constructor that has the same name as the class and called automatically at the time of instantiating a … [Read more...]

Abstract Class An abstract class is one that is intended only to be a base class of other classes. The 'abstract' modifier is used to make a class abstract. An abstract modifier indicates that there is some missing implementation that needs to be implemented in the class derived from it. The abstract class can have abstract and non-abstract members. An abstract class should have at least one abstract method, otherwise, there is no use of declaring that class as 'abstract.' Example of … [Read more...]
