Default parameterless constructorĪny method that doesn’t take any values (or) a that doesn’t have any parameters is called a parameterless or default constructor.
The following are the different types of constructors in C# programming language. Hence the one called by the compiler, which was not defined explicitly, is called the implicit constructor. When we try to call it, then the compiler will call the parameterless constructor by default. NOTE: Even though a constructor is not defined inside the class. i.e., the value of integer variable a = 0 and Boolean variable b as false. While executing, the compiler creates an implicit constructor to initialize variables a, b, and prints the default values. Here, we have not defined a constructor to initialize those variables but asked to print their values of them. In the above example program, a is an integer and b is a boolean variable defined, respectively. using System Ĭonsole.WriteLine("value of integer a is: " + p.a) Ĭonsole.WriteLine("value of boolean b is: " + p.b) Let us see how a C# default constructor is called to initialize the variables when it’s not defined inside the class. Except for the constructor, that defined with the access specifier static, all are non-static only. The C# Constructors are either static or non-static. We call it an implicit or default constructor. Otherwise, while executing, the compiler creates a constructor by default.
In contrast, the C# constructor is useful for creating the instance or object of the class.Ī programmer must define a constructor explicitly inside a class. ()Īs we already said that an object is created to access the fields and the member functions of the C# class. The syntax of the C# constructor is as shown below. The values required for executing the class are sent to it using constructors. In general, every class holds some fields or variables. The C# constructor doesn’t return any value, and hence it is said to be a non-value returning method. In general, the name of the constructor should be the same as the class name. The C# constructor is a type of method defined inside a class for initializing that class’s variables.
