--- title: Enumerations --- # 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 ```
