Tuple<T1,T2,T3,T4,T5>.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> 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 5 Tuple 物件的陣列，其中包含兩個測試群組中病患溫度的相關資料。 陣列的第一個元件會提供測試群組的數目，而第二個到第五個元件會以每小時間隔提供病患的溫度。 系統會 Tuple<T1,T2,T3,T4,T5>.Equals(Object) 呼叫 方法，以比較每個 Tuple<T1,T2,T3,T4,T5> 物件與其他 Tuple<T1,T2,T3,T4,T5> 物件。 輸出說明 Equals 只有在物件的所有五個元件 Tuple<T1,T2,T3,T4,T5> 都有相等值時，方法才會傳回 true 。

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>它是 物件。

• 其五個元件的類型與目前的實例相同。

• 其五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。
