중요

일부 정보는 릴리스되기 전에 상당 부분 수정될 수 있는 시험판 제품과 관련이 있습니다. Microsoft는 여기에 제공된 정보에 대해 어떠한 명시적이거나 묵시적인 보증도 하지 않습니다.

현재 Tuple<T1,T2,T3,T4> 개체가 지정된 개체와 같은지 여부를 나타내는 값을 반환합니다.

public:
 override bool Equals(System::Object ^ obj);

public override bool Equals (object obj);

public override bool Equals (object? obj);

override this.Equals : obj -> bool

Public Overrides Function Equals (obj As Object) As Boolean

매개 변수

obj: Object

이 인스턴스와 비교할 개체입니다.

반환

Boolean

현재 인스턴스가 지정된 개체와 같으면 true이고, 그렇지 않으면 false입니다.

예제

다음 예제에서는 특정 날짜 동안 온도에 대한 데이터를 세 번 제공하는 개체 배열 Tuple<T1,T2,T3,T4> 을 정의합니다. 메서드 Equals(Object) 는 모든 개체를 다른 Tuple<T1,T2,T3,T4> 모든 Tuple<T1,T2,T3,T4> 개체와 비교하기 위해 호출됩니다. 출력은 개체의 Equals(Object) 4개 구성 요소 모두에 동일한 값이 있는 경우에만 메서드가 Tuple<T1,T2,T3,T4> 반환 true 된다는 것을 보여 줍니다.

설명

매개 obj 변수는 다음 조건에서 현재 인스턴스와 동일한 것으로 간주됩니다.

개체입니다 Tuple<T1,T2,T3,T4> .
4개의 구성 요소는 현재 인스턴스와 동일한 형식입니다.
4개의 구성 요소는 현재 인스턴스의 구성 요소와 같습니다. 같음은 각 구성 요소에 대한 기본 개체 같음 비교자에 의해 결정됩니다.
