Is there a way to iterate through all enum values? [duplicate]

Answer 1

Little more "complicated" (maybe overkill) but I use these two methods to return dictionaries to use as datasources. The first one returns the name as key and the second value as key.

public static IDictionary ConvertEnumToDictionaryNameFirst()
{
  if (typeof(K).BaseType != typeof(Enum))
  {
    throw new InvalidCastException();
  }

  return Enum.GetValues(typeof(K)).Cast().ToDictionary(currentItem 
    => Enum.GetName(typeof(K), currentItem));
}

Or you could do

public static IDictionary ConvertEnumToDictionaryValueFirst()
{
  if (typeof(K).BaseType != typeof(Enum))
  {
    throw new InvalidCastException();
  }

  return Enum.GetNames(typeof(K)).Cast().ToDictionary(currentItem 
    => (int)Enum.Parse(typeof(K), currentItem));
}

This assumes you are using 3.5 though. You'd have to replace the lambda expressions if not.

Use:

  Dictionary list = ConvertEnumToDictionaryValueFirst();

  using System;
  using System.Collections.Generic;
  using System.Linq;
