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> 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物件陣列 Tuple<T1,T2,T3,T4> ，能提供特定一天中三個時間段的溫度資料。 Equals(Object)此方法被呼叫用來將每個Tuple<T1,T2,T3,T4>物件與其他物件Tuple<T1,T2,T3,T4>進行比較。輸出說明Equals(Object)該方法僅在物件四個元件true值相等時才會回傳Tuple<T1,T2,T3,T4>。

備註

在以下條件下，參數 obj 被視為等於當前實例：

它是一個 Tuple<T1,T2,T3,T4> 物件。
它的四個組件與目前實例類型相同。
其四個組件與當前實例相同。等號由每個元件的預設物件等式比較器決定。
