回傳一個值，表示目前 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 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

以下範例定義了五個 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 包含質數的物件。 接著會將第一個物件與剩餘的每個物件進行比較。 如輸出所示，只有第一個和最後一個 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 物件相等，因為它們擁有相同數量且值相同的分量。

備註

obj若參數符合以下所有條件，則視為當前實例：

  • 它是一個 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 物件。

  • 它擁有與當前實例相同類型的元件總數。

  • 其組件（包括巢狀組件）與當前實例的組件相同。 等號由每個元件的預設等號比較器決定。
