Which constructor call first in C#?

You can’t call a default constructor once you’ve created a constructor that takes arguments . You’ll have to create the no argument constructor yourself in order to make a call from the parameterized constructor. Yes, this will work.

In C# terms, the base constructor is executed first.

after the parametrized constructor. It was a bit of guess, but it seems to work . Don’t call it base construction, because using : base() wont call the parameter less constructor (of THIS class – if inherited it will call the constructor of the base class).

Prerequisite: Constructors in C# Static constructors are used to initialize the static members of the class and are implicitly called before the creation of the first instance of the class. Non-static constructors are used to initialize the non-static members of the class.
