Tuple<T1, T2, T3, T4, T5, T6, T7>.Item2 Property
Gets the value of the current Tuple<T1, T2, T3, T4, T5, T6, T7> object's second component.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
You can dynamically determine the type of the Item2 component in one of two ways:
By calling the GetType method on the value that is returned by the Item2 property.
By retrieving the Type object that represents the Tuple<T1, T2, T3, T4, T5, T6, T7> object, and retrieving the second element from the array that is returned by its Type.GetGenericArguments method.
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 1950, it retrieves the value of the Item2 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 // // New York 7,891,957 7,781,984 7,894,862 7,071,639 7,322,564 8,008,278 // Los Angeles 1,970,358 2,479,015 2,816,061 2,966,850 3,485,398 3,694,820 // Chicago 3,620,962 3,550,904 3,366,957 3,005,072 2,783,726 2,896,016
