قالب بندی تاریخ و زمان (Custom Date and Time) در سی شارپ

همانند هر داده دیگری، لازم است تا بتوان مقادیر مربوط با تاریخ و زمان را نیز در ساختارها و قالب های گوناگون و دلخواه نمایش داد. در این مقاله به چگونگی انجام این امر خواهیم پرداخت.

1. برای تنظیم قالب بندی زمان و تاریخ، فایل را به صورت زیر اصلاح کنید.

                
using System;
public class OrderProcessing
{
public static int Main()
{
// Price of items
const double PriceOneShirt     = 0.95;
const double PriceAPairOfPants = 2.95;
const double PriceOneDress     = 4.55;
const double TaxRate           = 0.0575;  // 5.75%
// Basic information about an order
string customerName, homePhone;
DateTime orderDate, orderTime;
// Unsigned numbers to represent cleaning items
uint numberOfShirts, numberOfPants, numberOfDresses;
// Each of these sub totals will be used for cleaning items
double subTotalShirts, subTotalPants, subTotalDresses;
// Values used to process an order
double totalOrder, taxAmount, salesTotal;
double amountTended, moneyChange;
Console.Title = "Georgetown Dry Cleaning Services";
Console.WriteLine("-/- Georgetown Dry Cleaning Services -/-");
// Request order information from the user
Console.Write("Enter Customer Name:  ");
customerName = Console.ReadLine();
Console.Write("Enter Customer Phone: ");
homePhone = Console.ReadLine();
Console.Write("Enter the order date(mm/dd/yyyy):  ");
orderDate = DateTime.Parse(Console.ReadLine());
Console.Write("Enter the order time(hh:mm AM/PM): ");
orderTime = DateTime.Parse(Console.ReadLine());
// Request the quantity of each category of items
Console.Write("Number of Shirts:  ");
numberOfShirts = uint.Parse(Console.ReadLine());
Console.Write("Number of Pants:   ");
numberOfPants = uint.Parse(Console.ReadLine());
Console.Write("Number of Dresses: ");
numberOfDresses = uint.Parse(Console.ReadLine());
// Perform the necessary calculations
subTotalShirts  = numberOfShirts  * PriceOneShirt;
subTotalPants   = numberOfPants   * PriceAPairOfPants;
subTotalDresses = numberOfDresses * PriceOneDress;
// Calculate the "temporary" total of the order
totalOrder      = subTotalShirts +
subTotalPants + 
subTotalDresses;
// Calculate the tax amount using a constant rate
taxAmount       = totalOrder * TaxRate;
// Add the tax amount to the total order
salesTotal      = totalOrder + taxAmount;
// Communicate the total to the user...
Console.WriteLine("\nThe Total order is: {0:C}",
salesTotal);
// and request money for the order
Console.Write("Amount Tended? ");
amountTended    = double.Parse(Console.ReadLine());
// Calculate the difference owed to the customer
// or that the customer still owes to the store
moneyChange = amountTended - salesTotal;
Console.Clear();
// Display the receipt
Console.WriteLine("====================================");
Console.WriteLine("-/- Georgetown Dry Cleaning Services -/-");
Console.WriteLine("====================================");
Console.WriteLine("Customer:    {0}", customerName);
Console.WriteLine("Home Phone:  {0}", homePhone);
Console.WriteLine("Order Date:  {0:D}", orderDate);
Console.WriteLine("Order Time:  {0:t}", orderTime);
Console.WriteLine("------------------------------------");
Console.WriteLine("Item Type  Qty Unit/Price Sub-Total");
Console.WriteLine("------------------------------------");
Console.WriteLine("Shirts     {0}   {1}       {2}",
numberOfShirts.ToString(),
PriceOneShirt.ToString("C"),
subTotalShirts.ToString("C"));
Console.WriteLine("Pants      {0}   {1}        {2}",
numberOfPants.ToString(),
PriceAPairOfPants.ToString("C"),
subTotalPants.ToString("C"));
Console.WriteLine("Dresses    {0}   {1}        {2}",
numberOfDresses.ToString(),
PriceOneDress.ToString("C"),
subTotalDresses.ToString("C"));
Console.WriteLine("------------------------------------");
Console.WriteLine("Total Order:   {0}",
totalOrder.ToString("C"));
Console.WriteLine("Tax Rate:      {0}",
TaxRate.ToString("P"));
Console.WriteLine("Tax Amount:    {0}", 
taxAmount.ToString("C"));
Console.WriteLine("Net Price:     {0}", 
salesTotal.ToString("C"));
Console.WriteLine("------------------------------------");
Console.WriteLine("Amount Tended: {0}", 
amountTended.ToString("C"));
Console.WriteLine("Difference:    {0}", 
moneyChange.ToString("C"));
Console.WriteLine("====================================");
System.Console.ReadKey();
return 0;
}
}
