Tuple<T1,T2,T3,T4,T5,T6>.Equals(Object) 方法

定義

命名空間:

System

組件:

System.Runtime.dll

組件:

mscorlib.dll

組件:

netstandard.dll

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

Boolean

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。
