Do not say his concept, if you want to build a computer classroom, first to have a room, the room to have n computers, there are n tables, n chairs, white boards, projectors and so on, these are what, just now we said, this is the object, can see the entity, Can say this computer classroom unit is this one entity object, they together compose this computer classroom, then we are the procedure, this and
need to provide the code for the destructor, but instead the default destructor performs the operation automatically. However, if you need to do some important things before you delete an object instance, you should provide a specific destructor.For example, if a variable is out of range, the code cannot access it, but the variable still exists somewhere in the computer's memory. Only in. NET runtime to perform its garbage collection, the instance is

Class Method
The essence of a class method is a single-piece method that lives in a single-piece class of this class. Three m
, all non-static constructors are also referred to as instance constructors. 2. Static ClassWe often want the class to contain only static members, and cannot be used to instantiate objects such as the console. A simple way to do this is to use a static class instead of setting the class's constructor to private. A static class can contain only static members and does not require an instance constructor because, by definition, it cannot be instantiated at all. However, a static class can have a
