The default initialization mechanism of the. NET system sets all objects to 0 [14]. We cannot block other value types.ProgramMembers Initialize all their members to 0 [15]. Therefore, we should use 0 as the default value of the value type.
Enumeration is a typical case. The enumerated type we created should never regard 0 as invalid. We know that all enumeration types inherit from system. valuetype. The default enumeration value starts from 0, but we can change this default behavior.

"BZOJ4285" Messenger description A.D. 8192, human entered the era of interstellar navigation. Under unremitting efforts, humans have captured n planets in the universe and built n-1 Interstellar lanes between these planets, allowing any two planets to reach each other through a single path. At the same time, there are some space jumping points in the universe, some jumping points have been found, and some are unknown, each jumping point connected to two planets, so that either of the two planets

Description Aliens refer to intelligent life beyond the Earth. The aliens are not as important as the people on Earth, but at least they should conform to our current understanding of the basic forms of life. For example, any life we know can be separated from liquid water, and are complex organisms that are based on organic molecules of chemical element ca

The code is as follows:Let Earthsorder = Planet.Earth.rawValue// Earthsorder is 37) possibleplanet is of type Planet? and equals Planet.uranusHowever, not all possible Int values can be found for a matching planet. Because of this, the constructor can return an optional enumeration member. In the example above, possiblePlanet it is the
code is nothing more than the gettemplate template file, get the parameters set by the server, and the logon user level, and then construct the page. Note that the user Level variable $ level is displayed. When the value of $ Level is greater than 0, the Administrator link is displayed. The $ level value represents the level defined in the system.mo file. 0 is a common player, 1 is a game operator, 2 is a game administrator, and 3 is an administrator.

initialization only to some extent, this will be discussed in the automatic initialization program inheritance.
When a user needs to have an initializer defined in a superclass, subclass, the initialization function must be defined by the user as the custom implementation. When overridden, it must be declared using the "override" keyword in subclasses to superclass.

calling its method.In addition to correcting the flaws of the int enumeration, enumeration types allow the addition of arbitrary methods and properties and implement arbitrary interfaces. They provide a high-quality implementation of all the object Methods (chapter 3rd), which implement Comparable (entry 14) and Serializable (12th), and design serialization for the arbitrary modification of enum types.So why do you want to add a method or property to an enumeration type? For starters, you might
