How to Convert Enum to List
Computer programming languages have many different ways of storing data. Most data is stored according to a type, which helps define its range of values. For example, a digit type can hold the values zero through nine. An "enum" is a special type that is determined by the user. An "enum" can store the days of the week, for example. You can use a language like C# to transform an "enum" into a list with a little bit of code.
