Tuple<T1, T2, T3, T4, T5, T6, T7>.Item7 Property

Gets the value of the current Tuple<T1, T2, T3, T4, T5, T6, T7> object's seventh component.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public T7 Item7 { get; }

Property Value

Type: T7
The value of the current Tuple<T1, T2, T3, T4, T5, T6, T7> object's seventh component.

You can dynamically determine the type of the Item7 component in one of two ways:

The following example defines an array of Tuple<T1, T2, T3, T4, T5, T6, T7> objects whose components contain population data for three U.S. cities (New York, Chicago, and Los Angeles) from 1950 through 2000. It then displays a table that lists the data. To display the population in 2000, it retrieves the value of the Item7 property for each Tuple<T1, T2, T3, T4, T5, T6, T7> object.

using System;
using System.Text.RegularExpressions;

public class Class1
{
   public static void Main()
   {
      // Create tuples containing population data for New York, Chicago,  
      // and Los Angeles, 1960-2000.
      Tuple<string, int, int, int, int, int, int>[] cities =
           { Tuple.Create("New York", 7891957, 7781984, 7894862, 7071639, 7322564, 8008278),
             Tuple.Create("Los Angeles", 1970358, 2479015, 2816061, 2966850, 3485398, 3694820),
             Tuple.Create("Chicago", 3620962, 3550904, 3366957, 3005072, 2783726, 2896016) };

      // Display tuple data in table. 
      string header = "Population in";
      Console.WriteLine("{0,-12} {1,66}", 
                        "City", new String('-',(66-header.Length)/2) + header + 
                                new String('-', (66-header.Length)/2));
      Console.WriteLine("{0,24}{1,11}{2,11}{3,11}{4,11}{5,11}\n", 
                        "1950", "1960", "1970", "1980", "1990", "2000");         

      foreach (var city in cities)                      
         Console.WriteLine("{0,-12} {1,11:N0}{2,11:N0}{3,11:N0}{4,11:N0}{5,11:N0}{6,11:N0}", 
                           city.Item1, city.Item2, city.Item3, city.Item4, 
                           city.Item5, city.Item6, city.Item7);
   }
}
// The example displays the following output: 
//   City          --------------------------Population in-------------------------- 
//                       1950       1960       1970       1980       1990       2000
