<![CDATA[
An enum type defines a group of constants. Each constant has a name and backend numeric value.
An enum is a value type.
The operators that work with enums are: = == != < > <= >= + - ^ & | ? += -= ++ - sizeof.
The following code defines an enum type wor week day:
using System;
enum WeekDay{
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
}
class Test
{
static void Main()
{
WeekDay day = WeekDay.Monday;
Console.WriteLine(day);
}
}
The output:
Monday
We can also compare the enum value.
using System;
enum WeekDay{
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
}
class Test
{
static void Main()
{
WeekDay day = WeekDay.Monday;
WeekDay day2 = WeekDay.Tuesday;
Console.WriteLine(day > day2);
if (day == WeekDay.Monday)
{
Console.WriteLine("it is monday");
}
}
}
The output:
False
it is monday
