回傳一個值，表示目前 Tuple<T1,T2,T3,T4,T5,T6> 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1960年至2000年間洛杉磯與紐約人口資料的六重組陣列。 每個六分之一的第一部分代表城市。 第一、第三和第四六人組包含紐約的資料。 第一六組是第四六組的重複。 第三個六分組將城市標示為「紐約市」而非「紐約」。 如範例所示，只有第四個六組等於第一個六組。

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,T5,T6> 物件。

  • 它的六個組件與當前實例類型相同。

  • 其六個組成部分與當前實例相同。 等號由每個元件的預設物件等式比較器決定。
