定義

現在の Tuple<T1,T2,T3,T4,T5> オブジェクトの 5 番目のコンポーネントの値を取得します。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

プロパティ値

T5 T5 T5 T5

現在の Tuple<T1,T2,T3,T4,T5> オブジェクトの 5 番目のコンポーネントの値。The value of the current Tuple<T1,T2,T3,T4,T5> object's fifth component.

次の例の配列を定義するTuple<T1,T2,T3,T4,T5>コンポーネントが含まれる米国の日付、1990 年と 2000 人口、この 10 年間でその population の変更およびその母集団の割合の変化で、状態の名前を含むオブジェクト。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. 配列を反復処理し、タプルの各コンポーネントの値を表示します。It then iterates through the array and displays the value of each component in a tuple.

using System;

注釈

型を動的に決定できます、Item2で 2 つの方法のいずれかのコンポーネント。You can dynamically determine the type of the Item2 component in one of two ways:

  • 呼び出すことによって、GetTypeメソッドによって返される値をItem2プロパティ。By calling the GetType method on the value that is returned by the Item2 property.

  • 取得することによって、Typeを表すオブジェクトをTuple<T1,T2,T3,T4>オブジェクトし、によって返される配列から 2 番目の要素を取得するそのType.GetGenericArgumentsメソッド。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.
