En del information gäller för förhandsversionen av en produkt och kan komma att ändras avsevärt innan produkten blir allmänt tillgänglig. Microsoft lämnar inga garantier, uttryckliga eller underförstådda, avseende informationen som visas här.
Returnerar ett värde som anger om det aktuella Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objektet är lika med ett angivet objekt.

Exempel
I följande exempel definieras fem Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objekt som innehåller primtal. Sedan jämförs det första objektet med vart och ett av de återstående objekten. Som utdata visar är endast de första och sista Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objekten lika, eftersom de har ett identiskt antal komponenter med identiska värden.

Kommentarer
Parametern obj anses vara lika med den aktuella instansen om den uppfyller alla följande villkor:
Det är ett Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objekt.
Den har samma totala antal komponenter som är av samma typ som den aktuella instansen.
Dess komponenter (inklusive dess kapslade komponenter) är lika med komponenterna i den aktuella instansen. Likhet bestäms av standardjämlikhetsjämförlikningsjämföraren för varje komponent.
