A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

There might be many constructors of which the correct implementation is automatically selected by the compiler. When this object is destroyed or deallocated, the Destructor function is automatically executed. For example when the scope of the object has finished or the object was dynamically allocated...
There is no such thing called ‘constructors’ and ‘destructors’ in C programming language or in structured languages, although there is no boundaries on defining such functions which act like them. You need to make functions which act like the constructors and destructors and then call them ...

the opposite relationship holds for destructors. So, if you have a constructor that allocates a resource and a destructor that deallocates the same resource, both functions typically have the same priority. The priorities for constructor and destructor functions are the same as those specified for ...
