Property Value

Type: T2

The value of the current Tuple<T1, T2, T3, T4> object's second component.

You can dynamically determine the type of the Item2 component in one of two ways:

The following example defines an array of Tuple<T1, T2, T3, T4> objects whose components contain the name of a city, a month of the year, and the average high and low temperatures for that month. It then retrieves and displays the value of each component.

using System;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      Tuple<string, int, double, double>[] temperatures = 
            { Tuple.Create("New York, NY", 4, 61.0, 43.0),
              Tuple.Create("Chicago, IL", 2, 34.0, 18.0), 
              Tuple.Create("Newark, NJ", 4, 61.0, 43.0),
              Tuple.Create("Boston, MA", 6, 77.0, 59.0),
              Tuple.Create("Detroit, MI", 9, 74.0, 53.0),
              Tuple.Create("Minneapolis, MN", 8, 81.0, 61.0) }; 
      // Display the array of 4-tuple objects.
      Console.WriteLine("{0,41}", "Temperatures");
      Console.WriteLine("{0,-20} {1,5}    {2,4}  {3,4}\n", 
                        "City", "Month", "High", "Low");
      foreach (var temperature in temperatures)
         Console.WriteLine("{0,-20} {1,5}    {2,4:N1}  {3,4:N1}", 
                           temperature.Item1, 
                           DateTimeFormatInfo.CurrentInfo.GetAbbreviatedMonthName(temperature.Item2 - 1), 
                           temperature.Item3, temperature.Item4);
   }
}
// The example displays the following output:
//                                    Temperatures
//       City                 Month    High   Low
//       
//       New York, NY           Mar    61.0  43.0
//       Chicago, IL            Jan    34.0  18.0
//       Newark, NJ             Mar    61.0  43.0
//       Boston, MA             May    77.0  59.0
//       Detroit, MI            Aug    74.0  53.0
//       Minneapolis, MN        Jul    81.0  61.0
