How to use the result of Enum.GetValues() method?

I'm new in c#. I want to know the how to convert the result of the method Enum.GetValues() into the array of string? This is my code :

using System;
using System.Linq;
namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            foreach (var item in Enum.GetValues(typeof(MyEnumList)))
                Console.WriteLine(item);
        }
    }
    public enum MyEnumList
    {
        egg, apple, orange, potato
    }
}

Now I don't want to have foreach on the result. I want to store the result as an string[] variable. Thank you.

If you want an array of names, you can just use Enum.GetNames Method

Retrieves an array of the names of the constants in a specified enumeration.

using System;
                    
public class Program
{
    public static void Main()
    {
        string[] names = Enum.GetNames(typeof(MyEnumList));
        Console.WriteLine("[{0}]", string.Join(",", names));
    }
}
public enum MyEnumList
{
    egg, apple, orange, potato
}

output:

[egg,apple,orange,potato]

If you want a string[] of the numeric values:

using System;
using System.Linq;
                    
public class Program
{
    public static void Main()
    {
        string[] enumAsStrings = Enum.GetValues(typeof(MyEnumList)) // strongly typed values
                                     .Cast<int>() // Get the _numeric_ values
                                     .Select(x => x.ToString()) // conv. to string
                                     .ToArray(); // give me an array
        Console.WriteLine("[{0}]",string.Join(",", enumAsStrings));
    }
}
public enum MyEnumList
{
    egg, apple, orange, potato
}

output:

[0,1,2,3]

Probably you want something like that:

    var enums = Enum.GetValues(typeof(MyEnumList)).Cast<MyEnumList>().Select(x=>x.ToString()).ToArray();
