c# convert enumb to int array

using System;

public class Example
{
	public static void Main()
	{
		string[] strings = new string[] {"1", "2", "3"};

		int[] ints = Array.ConvertAll(strings, s => int.Parse(s));
		Console.WriteLine(String.Join(",", ints));
	}
}

int[] result = enumArray.Cast<int>().ToArray();

object[] objarr = new object[] {1,2,3 };
int[] arr = objarr.Cast<int>().ToArray();

int[] b = Array.ConvertAll((int[])Enum.GetValues(typeof(TestEnum)), Convert.ToInt32);
