How to construct a C # base [4] class

The constructor method is used to create the object, and the object can be initialized in the constructor.
Constructors are special methods used to create objects, such as the method name and the class name, with no return value and no even void.
Constructors can have parameters, and the new object passes the function arguments.

If you do not specify a constructor, the class has a default parameterless constructor. If a constructor is specified, there is no longer a default parameterless constructor, and you need to write it yourself if you need a parameterless constructor.

Constructors can be overloaded, which means that there are multiple constructors with different parameters.
