C#- Given an an enum name as a string return all values of enum

Question

I have a list of enum names. This list could be more descriptive to have the enum path such as Library.Base.Enums.{EnumName} if that helps.The enums could be in different folders such as MyEnumCategories could be stored in the folder Library/Base/Enums/Category/ and MyEnumCities could be in Library/Base/Enums/Locations/. I have a growing list of enum names and I need to be able to get all the values stored in the enums from the list. I need to return all the values the enums as shown below:

List<string> enumNames=["MyEnumCategories","MyEnumCities"]
List<string> values = new List<strings>

public enum MyEnumCategories
{
    Service = 0,
    Corporate = 1,
    Enterprise = 2,
    AllSites = 3,
    IndividualSites = 4,
    Site = 5,
    Notification = 6
}
public enum MyEnumCities
{
    Chicago= 0,
    Boston= 1,
    NewYork= 2,
    Denvor= 3,
    Austin= 4,
    Seattle= 5,
    SanFrancisco= 6
}

OUTPUT: values =["Service","Corporate ","Enterprise ",...."Seattle","SanFrancisco",]

Quick and easy with linq. If you want to span multiple assemblies or add case insensitivity or partial matching, etc, you'll have a few extra bits to add.

var enumNames = new[] { "MyEnumCategories", "MyEnumCities" };
var enumTypes = Assembly.GetExecutingAssembly().GetTypes().Where(x => x.IsEnum && enumNames.Contains(x.Name));
var values = enumTypes.SelectMany(Enum.GetNames).ToArray();
