# 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 it's underlying integer value and visa versa:
|
|
|
|
```
|
|
Console.WriteLine($"Male: {(int)Gender.Male}");
|
|
Console.WriteLine($"Female: {(int)Gender.Female}");
|
|
```
|
|
|
|
## Output:
|
|
```
|
|
Male: 1
|
|
Female: 2
|
|
```
