Menu System for Currency Exchange

GLJORR

I am on semester break and doing old labs. My task here is to design a currency menu system using a switch statement. When I run it in a console, I have to input a number then I have to press the following numbers corresponding to their currency exchange. We I press example 1, it shows up with its constant double.

using System;

namespace Exchange
{
class Program
{
static void Main()
{
const double aud = 0.96, usd = 0.72, pounds = 0.54, yen = 73.83, euro = 0.65, rupees = 48.32, kina = 2.28, rand = 10.46;
double exchange, dollarOne, dollarTwo, dollarThree, dollarFour, dollarFive, dollarSix, dollarSeven, dollarEight;
char inputNumber = ' ';
int number = 0;
string temp;

        Console.WriteLine("How much money do you want to exchange?");

        temp = Console.ReadLine();
        exchange = Convert.ToDouble(temp);

        Console.WriteLine("Press 1 for Austrlian Dollars");
        Console.WriteLine("2 for US Dollars");
        Console.WriteLine("3 for English Pounds");
        Console.WriteLine("4 for Japanese Yen");
        Console.WriteLine("5 for Euro");
        Console.WriteLine("6 for Indian Rupees");
        Console.WriteLine("7 for PNG Kina");
        Console.WriteLine("8 for SA Rand");

        dollarOne = exchange * aud;
        dollarTwo = exchange * usd;
        dollarThree = exchange * pounds;
        dollarFour = exchange * yen;
        dollarFive = exchange * euro;
        dollarSix = exchange * rupees;
        dollarSeven = exchange * kina;
        dollarEight = exchange * rand;

        temp = Console.ReadLine();
        inputNumber = Convert.ToChar(temp);

        switch (number)
        {
            case 0:
                inputNumber = '1';
                Console.WriteLine("Australian Dollars - " + aud);
                break;

            case 1:
                inputNumber = '2';
                Console.WriteLine("US Dollars - " + usd);
                break;

            case 2:
                inputNumber = '3';
                Console.WriteLine("English Pound - " + pounds);
                break;

            case 3:
                inputNumber = '4';
                Console.WriteLine("Japanese Yen - " + yen);
                break;

            case 4:
                inputNumber = '5';
                Console.WriteLine("Euros - " + euro);
                break;

            case 5:
                inputNumber = '6';
                Console.WriteLine("Indians Rupees - " + rupees);
                break;

            case 6:
                inputNumber = '7';
                Console.WriteLine("PNG Kina - " + kina);
                break;

            case 7:
                inputNumber = '8';
                Console.WriteLine("SA Rand - " + rand);
                break;
        }
        Console.ReadLine();
    }
}
