Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>.Equals(Object) 方法
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,T7,TRest> 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
下列範例會定義包含質數的五 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 個 物件。 然後,它會比較第一個物件與每個剩餘的物件。 如輸出所示,只有第一個和最後 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 一個物件相等,因為它們具有相同值的元件數目相同。

備註
如果參數符合下列所有條件,則 obj
參數會被視為等於目前的實例:
其元件總數與目前實例的類型相同。
其元件 (包括其巢狀元件,) 等於目前實例的元件。 相等是由每個元件的預設相等比較子所決定。
