Keterangan

Jika panggilan ke Contains metode mengembalikan true, Anda dapat mengakses elemen yang ditentukan dalam koleksi dengan menggunakan sintaks DtsProperties[index]. Jika Contains metode mengembalikan false, properti ini memberikan pengecualian. Di C#, properti ini adalah pengindeks DtsProperties untuk kelas .
