重要

部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。

回傳一個值，表示目前 Tuple<T1,T2,T3,T4,T5> 物件是否等於指定物件。

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

參數

obj: Object

這個例子是要比較的對象。

傳回

Boolean

true如果當前實例等於指定的物件;否則，。 false

範例

以下範例定義了一個包含兩個測試組患者體溫資料的五元組物件陣列。陣列的第一部分提供測試組的數量，第二至第五部分則每小時提供病人的體溫。 Tuple<T1,T2,T3,T4,T5>.Equals(Object)此方法被呼叫用來將每個Tuple<T1,T2,T3,T4,T5>物件與其他物件Tuple<T1,T2,T3,T4,T5>進行比較。輸出說明Equals該方法只有在物件的true五個成分值相等時才會回傳Tuple<T1,T2,T3,T4,T5>。
