Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>.Equals(Object) メソッド

定義

現在の Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> オブジェクトが、指定されたオブジェクトと等しいかどうかを示す値を返します。

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

パラメーター

obj
Object

このインスタンスと比較するオブジェクト。

戻り値

現在のインスタンスが指定したオブジェクトと等しい場合は true。それ以外の場合は false

次の例では、素数を含む 5 つの Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> オブジェクトを定義します。 次に、最初のオブジェクトを残りの各オブジェクトと比較します。 出力に示すように、最初と最後 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> のオブジェクトのみが等しくなります。同じ値を持つ同じ数のコンポーネントがあるためです。

注釈

パラメーターは obj 、次のすべての条件を満たしている場合、現在のインスタンスと等しいと見なされます。

  • これは オブジェクトです Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>

  • 現在のインスタンスと同じ型のコンポーネントの合計数が同じです。

  • そのコンポーネント (入れ子になったコンポーネントを含む) は、現在のインスタンスのコンポーネントと同じです。 等値は、各コンポーネントの既定の等値比較子によって決定されます。
