A constructor is a special memberfunctionthat is called automatically when anobjectis created. In C++, a constructor has the same name as that of theclass, and it does not have a return type. For example, class
A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

Objects that are created by calling constructors explicitly, as in the preceding two examples, are unnamed and have a lifetime of the expression in which they are created. This is discussed in greater detail inTemporary Objects. It is usually safe to call any member function from within a co...
In Python, constructors are special methods used to initialize objects when a class is created. In this chapter, we will learn how to define and use constructors, understand the role of the__init__method with the help of examples.
Here are two examples to illustrate the use of primary constructors in C# 12, one for a class and one for a struct. Class Example with Primary Constructor. publicclassEmployee(stringName,intAge,stringDepartment); C# Copy In this example, the Employee is a class with three properties: Name,...

Instance constructors in C# create and initialize any instance member variables when you use the new expression to create an instance of a type.
Primary constructors in C# 12 can be used in classes and structs as well as record types. Here’s how they make your code cleaner and more concise.
