Enumerations
An enumeration is a set of named integer constants that is declared using the enum
keyword.
Example
enum Gender
{
Male,
Female
}
By default, the integer values start at 0 and increase by 1, for each enumeration name i.e. Male = 0, Female = 1 etc.
These can be overridden by specifying an integer value for any of the enumeration names.
Example
enum Gender
{
Male = 1,
Female
}
In this case, the integer values will start at 1 and increase from there.
To use an enum, you can declare a variable of its type and assign a value to it:
Gender myVar = Gender.Male;
You can also cast an enumeration name value to its underlying integer value and vice versa:
Console.WriteLine($"Male: {(int)Gender.Male}");
Console.WriteLine($"Female: {(int)Gender.Female}");
Output:
Male: 1
Female: 2
