C# Class:
Reference types
A type that is defined as a Class is a reference type. At run time, when you declare a variable of a reference type, the variable contains the value null until you explicitly create an instance of the class by using the new operator.
//Declaring a object of type clsStudent
clsStudent objStud = new clsStudent();
//Declaring another object of the same type, assigning it the value of the first object.
clsStudent objStud1 = objStud ;
When the object is created, enough memory is allocated on the managed heap for that specific object, and the variable holds only a reference to the location of said object.
Declaring Classes:
Classes are declared by using the class keyword followed by a unique identifier, as shown in the following example:
//[access modifier] - [class] - [class name]
public class clsStudent
{
// Fields, properties, methods and events go here...
}
The class keyword is preceded by the access level. Because public is used in this case, anyone can create instances of this class. The name of the class follows the classkeyword. Fields, properties, methods, and events on a class are collectively referred to as class members. They are defined in class body.
