Enum Extensions

Tango.Linq.EnumExtensions

This class contains two different methods to deal with enum types as IEnumerable<T> collections, where T is equals to the enum type.

Methods

Name	Parameters	Returns	Description
AsEnumerable		IEnumerable<T>	Cast a T enum to an IEnumerable which each element is an enum option.
AsEnumerableSkipZero		IEnumerable<T>	Cast a T enum to an IEnumerable which each element is an enum option, except by the zero value option.

Usage

You can transform an enum type defined by T to an IEnumerable<T>. Simplily executes the AsEnumerable method with enum type.

See the code bellow:

enum Options
{
  None = 0,
  FirstOption = 1,
  SecondOption = 2,
  ThirdOption = 3
}

IEnumerable<Options> result = EnumExtensions.AsEnumerable<Options>();

// result = [None, FirstOption, SecondOption, ThirdOption]

You can ignore the zero value by using AsEnumerableSkipZero method, if you need.

enum Options
{
  None = 0,
  FirstOption = 1,
  SecondOption = 2,
  ThirdOption = 3
}

IEnumerable<Options> result = EnumExtensions.AsEnumerable<Options>();

// result = [FirstOption, SecondOption, ThirdOption]
