Do we need default constructor in C#?

A default constructor is a constructor that either has no parameters, or if it has parameters, all the parameters have default values . If no user-defined constructor exists for a class A and one is needed, the compiler implicitly declares a default parameterless constructor A::A() .

Constructor is a method in A class which will get executed when its object is created. … In case we don’t provide any constructor in the class, the compiler will create a default constructor for that particular class. So by default there will be one constructor of the class and it’s mandatory.

A constructor with no parameters is called a default constructor. A default constructor has every instance of the class to be initialized to the same values. The default constructor initializes all numeric fields to zero and all string and object fields to null inside a class.5 Kas 2020
