Definisi

Ruang nama:

Microsoft.SqlServer.Dts.Runtime

Rakitan:

Microsoft.SqlServer.ManagedDTS.dll

Mengembalikan Boolean yang menunjukkan apakah item dalam koleksi dapat diakses oleh indeks tanpa melemparkan pengecualian.

public:
 bool Contains(System::Object ^ index);

public bool Contains (object index);

member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

Parameter

index

Object

Nama, identitas, ID, atau indeks Configuration objek untuk ditemukan dalam koleksi.

Mengembalikan

Boolean

Boolean yang menunjukkan apakah koleksi dapat diakses berdasarkan nama, identitas, ID, atau indeks. Nilai true menunjukkan bahwa koleksi dapat diakses dengan menggunakan sintaks Configurations[index]. Nilai false menunjukkan bahwa pengindeksan tidak dapat digunakan untuk mengambil item dari Configurations koleksi; menggunakan properti ini melemparkan pengecualian.

Contoh

Contoh kode berikut menggunakan Contains metode untuk melihat apakah sintaks item tersedia.
