Contoh

Contoh berikut mendefinisikan array Tuple<T1,T2,T3,T4,T5,T6,T7> objek yang komponennya berisi data populasi untuk tiga kota AS (New York, Chicago, dan Los Angeles) dari 1950 hingga 2000. Kemudian menampilkan tabel yang mencantumkan data. Untuk menampilkan populasi pada tahun 1990, ia mengambil nilai Item6 properti untuk setiap Tuple<T1,T2,T3,T4,T5,T6,T7> objek.

Keterangan

Anda dapat menentukan jenis Item6 komponen secara dinamis dengan salah satu dari dua cara:

• Dengan memanggil GetType metode pada nilai yang dikembalikan oleh Item6 properti .

• Dengan mengambil Type objek yang mewakili Tuple<T1,T2,T3,T4,T5,T6,T7> objek, dan mengambil elemen keenam dari array yang dikembalikan oleh metodenya Type.GetGenericArguments .
