|
using System;
using System.Collections;
class Product {
string name;
double cost;
int onhand;
public Product(string n, double c, int h) {
name = n;
cost = c;
onhand = h;
}
public override string ToString() {
return
String.Format("{0,-10}Cost: {1,6:C} On hand: {2}",
name, cost, onhand);
}
}
class MainClass {
public static void Main() {
ArrayList inv = new ArrayList();
// Add elements to the list
inv.Add(new Product("A", 5.9, 3));
inv.Add(new Product("B", 8.2, 2));
inv.Add(new Product("C", 3.5, 4));
inv.Add(new Product("D", 1.8, 8));
Console.WriteLine("Product list:");
foreach(Product i in inv) {
Console.WriteLine(" " + i);
}
}
}
Output Product list:
A Cost: $5.90 On hand: 3
B Cost: $8.20 On hand: 2
C Cost: $3.50 On hand: 4
D Cost: $1.80 On hand: 8
