## Definição

Obtém o valor do quarto componente do objeto Tuple<T1,T2,T3,T4,T5,T6> atual.Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6> object's fourth component.

``````public:
property T4 Item4 { T4 get(); };``````
``public T4 Item4 { get; }``
``member this.Item4 : 'T4``
``Public ReadOnly Property Item4 As T4``

T4

O valor do quarto componente do objeto de Tuple<T1,T2,T3,T4,T5,T6> atual.The value of the current Tuple<T1,T2,T3,T4,T5,T6> object's fourth component.

## Exemplos

O exemplo a seguir define uma matriz de objetos Tuple<T1,T2,T3,T4,T5,T6> cujos componentes contêm dados de preenchimento para três cidades dos EUA (Nova York, Chicago e Los Angeles) de 1960 até 2000.The following example defines an array of Tuple<T1,T2,T3,T4,T5,T6> objects whose components contain population data for three U.S. cities (New York, Chicago, and Los Angeles) from 1960 through 2000. Em seguida, ele exibe em uma tabela que lista os dados.It then displays a table that lists the data. Para exibir a população em 1980, ela recupera o valor da propriedade Item4 para cada objeto Tuple<T1,T2,T3,T4,T5,T6>.To display the population in 1980, it retrieves the value of the Item4 property for each Tuple<T1,T2,T3,T4,T5,T6> object.
