ICollection Mendapatkan yang berisi kunci di OdbcConnectionStringBuilder.

public:
 virtual property System::Collections::ICollection ^ Keys { System::Collections::ICollection ^ get(); };

public override System.Collections.ICollection Keys { get; }

member this.Keys : System.Collections.ICollection

Public Overrides ReadOnly Property Keys As ICollection

Nilai Properti

ICollection

Yang ICollection berisi kunci dalam OdbcConnectionStringBuilder.

Contoh

Contoh aplikasi konsol berikut membuat baru OdbcConnectionStringBuilder. Kode mengulang melalui yang ICollection dikembalikan oleh properti yang Keys menampilkan pasangan kunci/nilai.

Catatan

Contoh ini mencakup kata sandi untuk menunjukkan cara OdbcConnectionStringBuilder kerja dengan string koneksi. Di aplikasi Anda, kami sarankan Anda menggunakan Autentikasi Windows. Jika Anda harus menggunakan kata sandi, jangan sertakan kata sandi yang dikodekan secara permanen dalam aplikasi Anda.
