I'm using asp.net core to develop REST API and I have few enum values that to be expose to API response. And I'm able to do that but client developer don't know what are the enum's values. So I want to expose all enum values in the response.

Suppose I have following enum:

public enum niceEnum
{
   itemA = 1,
   itemB = 2,
   itemC = 3
}

And wan to show in response as:

1, itemA
2, itemB
3, itemC

How we can do this using dictionary?

Use following code

var dict1 = Enum.GetValues(typeof(niceEnum))
               .Cast<niceEnum>()
               .ToDictionary(t => t.ToString(), t => (int)t );

Following is an Enum extension that converts it to a Dictionary:

Dictionary<Int32, String> dt = niceEnum.ToDictionary();

public static Dictionary<int, string> ToDictionary(this Enum value)
{
   return Enum.GetValues(typeof(value))
               .Cast<value>()
               .ToDictionary(t => t.ToString(), t => (int)t );
}
