參數

• packageStream
  型別：System.IO.Stream
  Stream to which to write the package.

• databaseName
  型別：System.String
  Name of the source database.

• applicationName
  型別：System.String
  String identifier for the DAC application.

• applicationVersion
  型別：System.Version
  Version of the DAC application.

• applicationDescription
  型別：System.String
  Optional string summary of the DAC application.

• tables
  型別：System.Collections.Generic.IEnumerable<Tuple<String, String>>
  Optional enumerable used to retrieve enumerator over set of tables for which data should be exported. For each Tuple in the enumeration the first item specifies the schema of the table, and the second specifies the base identifier of the table. If the value for this parameter is a null reference, no data will be exported.

• extractOptions
  型別：Microsoft.SqlServer.Dac.DacExtractOptions
  Optional DacExtractOptions instance used to specify options that affect the behavior of package extraction.

• cancellationToken
  型別：System.Nullable<CancellationToken>
  Optional CancellationToken that can be used to indicate that the operation should be cancelled. Use of this object does not guarantee that the operation will be cancelled.
