DtsErrors.Contains(Object) Metode

Definisi

Ruang nama:

Microsoft.SqlServer.Dts.Runtime

Rakitan:

Microsoft.SqlServer.ManagedDTS.dll

Mengembalikan Boolean yang menunjukkan apakah item dalam koleksi dapat diakses dengan menggunakan pengindeksan 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

Nomor kesalahan, indeks, atau kode DtsError deskripsi objek.

Mengembalikan

Boolean

Boolean yang menunjukkan apakah koleksi dapat diakses oleh kode deskripsi, nomor kesalahan, atau indeks. Nilai true menunjukkan bahwa koleksi dapat diakses dengan menggunakan sintaks DtsErrors[index]. Nilai false menunjukkan bahwa pengindeksan tidak dapat digunakan untuk mengambil item dari DtsErrors koleksi.

Contoh

Contoh kode berikut membuat tugas Kirim Email dan menambahkannya ke paket. Tidak semua properti yang diperlukan dari tugas Kirim Email diatur, jadi ketika paket berjalan, ada kesalahan dan peringatan dalam DtsErrors koleksi dan DtsWarnings . Metode Contains ini digunakan untuk melihat apakah koleksi dapat diakses menggunakan DtsErrors[index] sintaks, dan jika demikian, mendapatkan beberapa properti menggunakan sintaks tersebut.
