get values(fields) of enum from reflected string representation

I have a string representation of an enum.

string val = "namespace_name.enum_name";

I can use this to get type of enum.

Type myType = Type.GetType(val);

Now I see myType.Name = actual_enum_name and other informations, good. I have tried to obtain the actual enum values using this information and not successful.

I have tried using Enum.Getvalues, however I got stuck in converting the myType, which is System.Type to EnumType, which is what Enum.Getvalues require(?).

I have tried to actually create an Enum object based on the information obtained and got stuck.

How can I get actual fields (list of members) of that enum from here?

That should work as is, no conversion required. Enum.GetValues() takes a Type. The code below works.

namespace enumtest
{
    public enum Mine
    {
        data1,
        data2
    }

    class Program
    {
        static void Main(string[] args)
        {
            Type myenum = Type.GetType("enumtest.Mine");

            foreach (var curr in Enum.GetValues(myenum))
            {
                Console.WriteLine(curr.ToString());
            }
        }
    }
}

This allows you to construct instances of an enum value like this:

namespace enumtest
{
    public enum Mine
    {
        data1,
        data2
    }

    class Program
    {
        static void Main(string[] args)
        {
            Type myenum = Type.GetType("enumtest.Mine");

            // Let's create an instance now
            var values = Enum.GetValues(myenum);
            var firstValue = values.GetValue(0);
            Mine enumInstance = (Mine)Enum.Parse(myenum, firstValue.ToString());

            Console.WriteLine("I have an instance of the enum! {0}", enumInstance);
        }
    }
}

Suppose i have an Enum ContactNumberType then to get values use

string[] names = Enum.GetValues(typeof(ContactNumberType));

because GetValues() method returns an array
