'Декларация
Public Property BatchSize As Long

'Применение
Dim instance As BulkInsertTask
Dim value As Long

    long long get () sealed;

Значение свойства

Тип: System. . :: . .Int64
A Long that indicates the number of rows in each batch.

Реализует

IDTSBulkInsertTask. . :: . .BatchSize

Замечания

The default value is 0, which means the whole data file. If you set BatchSize to zero, the data is loaded in a single batch.

Примеры

The following example creates a BulkInsertTask, and then shows the default settings of the properties, including the BatchSize, by using the TaskHost. The sample then sets two fields to show how to set field values.

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

            TaskHost th = exec1 as TaskHost;

            // List the default values of the Bulk Insert task
