Parallel array

Question

This program is for question 4. When the area code is 262 program is executing well but program is not working for other area codes. Please correct the error. I attach the question.

using System;

namespace _6e4
{
class Program
{
static void Main(string[] args)
{
int[] code = {262, 414, 608, 715, 815, 920};
double[] rate = {0.07, 0.10, 0.05, 0.16, 0.24, 0.14};
double cost;

Console.Write("Enter the area code ");
string s = Console.ReadLine();

Console.Write("Number of minutes talk ");
string t = Console.ReadLine();

for (int x = 0; x < code.Length; ++x)
{
if(Convert.ToInt32(s)==code[x])
{
cost = rate[x] * Convert.ToDouble(t);
Console.WriteLine("Total cost = {0}", cost.ToString("C"));
x = code.Length;
}
Console.ReadKey();
}
}
}
}
