If you declare an empty constructor, the C# compiler will not dynamically generate a parameter-less constructor . If you do not use an access modifier with the constructor, it will also become a private constructor by default.

Imagine that you could create a class that represents files, but without constructors, you couldn’t create any files based on the class.
Read moreHow do I call a parameterized constructor from another class in C#?
To call one constructor from another within the same class (for the same object instance), C# uses a colon followed by the this keyword, followed by the parameter list on the callee constructor’s declaration . In this case, the constructor that takes all three parameters calls the constructor that takes two parameters.
