定義
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。
傳回值,這個值表示目前的 Tuple<T1,T2,T3,T4,T5,T6> 物件是否等於指定的物件。
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
與這個執行個體相互比較的物件。
傳回
如果目前的執行個體和指定的物件相等,則為 true
,否則為 false
。
範例
下列範例會定義一個包含從 1960 年到 2000 年洛杉磯和紐約人口資料的性別資料陣列。 每個性別的第一個元件會識別城市。 第一個、第三和第四個性別包含紐約的資料。 第一個性別是第四個性別的複本。 第三個性別會將城市識別為「紐約市」,而不是「紐約」。 如範例所示,只有第四個性別等於第一個性別。

備註
參數 obj
在下列情況下會被視為等於目前的實例:
Tuple<T1,T2,T3,T4,T5,T6>它是 物件。
其六個元件的類型與目前的實例相同。
其六個元件等於目前實例的元件。 是否相等由每個元件的預設物件相等比較子決定。
