Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>.Rest 속성

정의

현재 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 개체의 나머지 구성 요소를 가져옵니다.Gets the current Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object's remaining components.

public:
 property TRest Rest { TRest get(); };
public TRest Rest { get; }
member this.Rest : 'Rest
Public ReadOnly Property Rest As TRest

속성 값

TRest

현재 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 개체의 나머지 구성 요소입니다.The value of the current Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object's remaining components.

예제

다음 예에서는 디트로이트, Michigan의 도시에 대 한 인구 데이터를 포함 하는 17 튜플 개체를 1860에서 2000으로 만듭니다.The following example creates a 17-tuple object that contains population data for the city of Detroit, Michigan, from 1860 to 2000. 17 튜플의 일곱 번째 구성 요소는 1900의 모집단입니다.The seventh component of the 17-tuple is the population in 1900. 이 예제에서는 속성을 사용 하 여 Rest 여덟 번째-14 번째 구성 요소의 값을 검색 하 고 Rest 중첩 된 개체의 속성을 사용 하 여 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 나머지 구성 요소의 값을 검색 합니다.The example uses the Rest property to retrieve the values of the eighth through fourteenth components, and it uses the Rest property of the nested Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object to retrieve the values of the remaining components.

설명

Rest속성은 Tuple 튜플의 n 번째 구성 요소에 대 한 액세스를 허용 하는 중첩 된 개체를 반환 합니다.The Rest property returns a nested Tuple object that allows access to the eighth though n th components of the tuple. 튜플의 총 구성 요소 수에 따라 여덟 번째부터 14 번째 구성 요소의 값은 중첩 된 Tuple 개체의 속성을 통해 검색할 수 있습니다 Item1 Item7 .Depending on the total number of components in the tuple, the values of the eighth through fourteenth components can be retrieved from the nested Tuple object's Item1 through Item7 properties. 그런 다음 Rest 중첩 된 개체의 속성을 사용 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 하 여 Tuple 다음 중첩 수준에서 개체를 검색할 수 있습니다.You can then use the Rest property of a nested Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object to retrieve the Tuple object at the next level of nesting.

Tuple Rest 형식 이름에서 숫자를 추출 하 여 속성에 의해 반환 되는 중첩 된 개체의 구성 요소 수를 동적으로 결정할 수 있습니다.You can dynamically determine the number of components in a nested Tuple object that is returned by the Rest property by extracting the digit from its type name. 다음 예제에서 이에 대해 설명합니다.The following example provides an illustration.
