![]() The copy constructor is used to create an object by copying all of its variables(attributes) from another object. Public Student(string n, string id, int rno)Ĭonsole.WriteLine(name + "\n" + id + "\n" + roll_no) In the code example above, we have specified the default constructor ourselves, but even if we don't do that, the compiler will automatically assign a default contructor to the class which is used for initialization of object of the class.Ī constructor with at least one parameter is called as parameterized constructor.įilename: Program.cs (Example of the parameterized constructor) using System The default constructor should have public access.įilename: Program.cs (Example of default constructor) using System Ĭonsole.WriteLine("Default Constructor Invoked!") Ĭonsole.WriteLine(s.name + "\n" + s.ID + "\n" + s.roll_no) The default constructor is added to a class by default if you don't add any constructor to your class. If a class doesn't have a constructor then a default constructor gets called when object is created. which other class can call the constructorĪ default constructor is parameterless. The constructor of a class must have the same name as the class in which it residesĪ class can have any number of constructorsĪ constructor can never be abstract, final, static and synchronizedĪ constructor doesn't have a return type but neither the return type is voidĬonstructors can have access modifiers along with it to control its access i.e. It is associated with a class and get automatically invoked when the classes instance (i.e., objects) are created. When we create Class in C#, every class should have a constructor which is used to initialize the object of the class.Ĭonstructors are the special method of the class which is used to initialize the data members of the new object. Also, the practical examples will help you to understand the concept of each constructor and its usage. In this tutorial, we will learn about constructors and its different types.
