Iterating the values of an enum (enumeration type) in C#

Iterating the values of an enum (enumeration type) in C#

Use this generic helper function to get the values of the enum:

static T[] GetValuesOfEnum<T>() where T : struct, Enum => (T[]) Enum.GetValues(typeof(T));

Example:

enum Color
{
  Red, Green, Blue
}

void PrintColors()
{
  foreach(var color in GetValuesOfEnum<Color>())
  {
    Console.WriteLine(color);
  }
}
