Features of the "C #" constructor

1. Its function name is the same as the class name;
2. It can be overloaded;
3. Cannot specify a return type, even if it is void;
4. Although in general, constructors are not explicitly called, they are called automatically when an object is created. However, it is not possible to display the call. Sometimes it is necessary to display the call, as long as the parent class has a constructor with parameters, the constructor for calling the parent class must be displayed in the subclass, because the constructor of the subclass cannot find the constructor of the parent class when it is instantiated (the subclass does not have to show the call when the parent class has its own write-without-argument constructor).
