Definição
Obtém o valor do quinto componente do objeto Tuple<T1,T2,T3,T4,T5> atual.Gets the value of the current Tuple<T1,T2,T3,T4,T5> object's fifth component.
public:
property T5 Item5 { T5 get(); };
public T5 Item5 { get; }
member this.Item5 : 'T5
Public ReadOnly Property Item5 As T5
Valor da propriedade
- T5
O valor do Tuple<T1,T2,T3,T4,T5> quinto componente do objeto atual.The value of the current Tuple<T1,T2,T3,T4,T5> object's fifth component.
Exemplos
O exemplo a seguir define uma matriz de Tuple<T1,T2,T3,T4,T5> objetos cujos componentes contêm o nome de um estado nas datas Unidas, sua população em 1990 e 2000, sua população é alterada neste período de 10 anos e a alteração percentual em sua população.The following example defines an array of Tuple<T1,T2,T3,T4,T5> objects whose components contain the name of a state in the United Dates, its population in 1990 and 2000, its population change in this 10-year period, and the percentage change in its population. Em seguida, ele itera pela matriz e exibe o valor de cada componente em uma tupla.It then iterates through the array and displays the value of each component in a tuple.
using System;
public class Example
{
public static void Main()
{
// Define array of tuples reflecting population change by state, 1990-2000.
Tuple<string, int, int, int, double>[] statesData =
{ Tuple.Create("California", 29760021, 33871648, 4111627, 13.8),
Tuple.Create("Illinois", 11430602, 12419293, 988691, 8.6),
Tuple.Create("Washington", 4866692, 5894121, 1027429, 21.1) };
// Display the items of each tuple
Console.WriteLine("{0,-12}{1,18}{2,18}{3,15}{4,12}\n", "State",
"Population 1990", "Population 2000", "Change",
"% Change");
foreach(Tuple<string, int, int, int, double> stateData in statesData)
Console.WriteLine("{0,-12}{1,18:N0}{2,18:N0}{3,15:N0}{4,12:P1}",
stateData.Item1, stateData.Item2,
stateData.Item3, stateData.Item4, stateData.Item5/100);
}
}
// The example displays the following output:
// State Population 1990 Population 2000 Change % Change
//
// California 29,760,021 33,871,648 4,111,627 13.8 %
// Illinois 11,430,602 12,419,293 988,691 8.6 %
// Washington 4,866,692 5,894,121 1,027,429 21.1 %

Comentários
É possível determinar dinamicamente o tipo do componente Item2 de duas maneiras:You can dynamically determine the type of the Item2 component in one of two ways:
Chamando o método
GetTypeno valor retornado pela propriedade Item2.By calling theGetTypemethod on the value that is returned by the Item2 property.Recuperando o objeto Type que representa o objeto Tuple<T1,T2,T3,T4> e recuperando o segundo elemento da matriz retornada pelo método Type.GetGenericArguments.By retrieving the Type object that represents the Tuple<T1,T2,T3,T4> object, and retrieving the second element from the array that is returned by its Type.GetGenericArguments method.
