Enum types in C #

Recently encountered an enumeration type, just by the way.

The base class of Enum Enum, which can be any integral type except Char. If you do not make a display declaration, the default is reshape (Int32).

declares an enum type :

        <summary>            ///color///</summary> public enum People {[Description ("Baby")]            Baby = 0,            [Description ("Child")]            children = 5,            [Description ("Youth")]            Youth =,            [Description ("Old Man") )] Old            =        

Enum is converted to String type:

(1) using the Object.ToString () method:

People.Baby.ToString ();

(2) using the static method of enum GetName:

Enum.getname (typeof (People), 0) Enum.getname (typeof (People), People.baby)

The string type is converted to an enum:

(1) The static method of using Enum, parse:

(people) Enum.parse (typeof (People), "children")

Enum is converted to an integer:

(1) Forced conversion

(int) People.youth; (byte) people.youth;//byte range of values, 0-255, caution some will overflow

convert int to enum:

(people) (60)
(people) Enum.toobject (typeof (People), 60)

Get an array of enum strings :

foreach (var item in Enum.getnames (typeof (People))) {    Console.WriteLine (item);}

Determine if a shape is defined in an enum :

Enum.isdefined (typeof (People), 60);//returns TRUE or False

The result is:
