Program argument input values: Converts degrees Celsius to degrees Fahrenheit
using System; public class PassArguments { public static void Main(String[] args) { double hotC, coldC; double hotF, coldF; if (args.Length != 2) { Console.WriteLine ("Enter a hot and a cold temerature as program arguments."); return; } hotC = double.Parse(args[0]); hotF = 9.0*hotC/5.0 + 32.0; Console.WriteLine ("The Fahrenheit temperature is: {0:F1}", hotF); coldC = double.Parse(args[1]); coldF = 9.0*coldC/5.0 + 32.0; Console.WriteLine ("The Fahrenheit temperature is: {0:F1}", coldF); } }
To Four Digit Year
using System; using System.Globalization; class Class1 { static void Main(string[] args) { Calendar MyCalendar = new GregorianCalendar(); Console.WriteLine(MyCalendar.ToFourDigitYear(32)); Console.WriteLine(MyCalendar.ToFourDigitYear(28)); } }
Two Digit Year Max
using System; using System.Globalization; class Class1 { static void Main(string[] args) { Calendar MyCalendar = new GregorianCalendar(); CultureInfo MyCulture = new CultureInfo("es-ES"); DateTime MyDate = new DateTime(2006,8,22,15,30,0,0); Console.WriteLine(MyCalendar.TwoDigitYearMax); } }
ToString(): make it culture aware
using System; using System.Globalization; class Class1 { static void Main(string[] args) { Calendar MyCalendar = new GregorianCalendar(); CultureInfo MyCulture = new CultureInfo("es-ES"); DateTime MyDate = new DateTime(2006,8,22,15,30,0,0); Console.WriteLine(MyCalendar.AddMinutes(MyDate, 15). ToString("G", MyCulture)); } }
