Powers with a for loop

This C# code takes 2 variables and then powers the second variable to the first. For example...

Enter your variable:
5
Enter your power:
3
125


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Powers
{
    class Program
    {
        static void Main(string[] args)
        {
            power();
        }
        private static void power()
        {
            while (1 == 1)
            {
                Console.WriteLine("Enter your variable: ");
                double x = double.Parse(Console.ReadLine());
                Console.WriteLine("Enter your power: ");
                double y = double.Parse(Console.ReadLine());
                double z = x;
                for (int i = 1; i < y; i++)
                {
                    z = x * z;
                }
                Console.WriteLine(z);
                string a = Console.ReadLine();
            }
        }
    }
}
