05. Destructors

Use of destructors: (1). You cannot define destructors in structs, you can only use destructors on classes. (2). A class can have only one destructor. (3). Destructors cannot be inherited and overloaded (4). Destructors cannot be called manually, it can only be called automatically (5). Destructors have neither modifiers nor parameters
Syntax: ~ Class name () {
}
When will the destructor be executed? The destructor is executed when the program finishes.
What is the function of destructors? Help us release resources.
Why do you have destructors? There is an automatic recycling mechanism in C #, but when the program is finished, the GC may not be able to recycle the garbage immediately, and if we want to recycle this part of the garbage right away, then we need to use the destructor.
