It is a value type used to assign a set of constant names to a group of integer values
making the constants more readable.
This Enumeration is declared inside a namespace or class or structure using the enum keyword.
Syntax:
enum Enum_Name
{
X1;
X2;
X3;
..so on
}
By default, the first constant value is 0 and the next values are increased by 1.
Example 1:
using System;
namespace SampleProgram {
enum Rating {
VeryPoor;
Poor;
Average;
Good;
Excellent;
}
class MySample {
public static void Main(string[] args) {
Console.WriteLine(“VeryPoor Rating: ” + (int) Rating.VeryPoor);
Console.WriteLine(“Poor Rating: ” + (int) Rating.Poor);
Console.WriteLine(“Average Rating: ” + (int) Rating.Average);
Console.WriteLine(“Good Rating: ” + (int) Rating.Good);
Console.WriteLine(“Excellent Rating: ” + (int) Rating.Excellent);
}
}
}
The output will be:
very poor Rating :0
Poor Rating:1
Average Rating:2
Good Rating :3
Excellent Rating:4
Example 2:
enum MyCustomEnum
{
Y1,
Y2,
Y3,
Y4=8,
Y5,
Y6
}
Here the integer values will assign from 0 as default. As the Y4 is assigned to value 8,
the next Y5 is incremented by 1 with the precedence value 8 then the value of Y5 is 9 (8+1)
as below.
0,1,2,8,9,10
