Extract(Stream, String, String, Version, String, IEnumerable<Tuple<String,String>>, DacExtractOptions, Nullable<CancellationToken>)

将架构从数据库提取到包中。

public void Extract(System.IO.Stream packageStream, string databaseName, string applicationName, Version applicationVersion, string applicationDescription = default, System.Collections.Generic.IEnumerable<Tuple<string,string>> tables = default, Microsoft.SqlServer.Dac.DacExtractOptions extractOptions = default, System.Threading.CancellationToken? cancellationToken = default);

member this.Extract : System.IO.Stream * string * string * Version * string * seq<string * string> * Microsoft.SqlServer.Dac.DacExtractOptions * Nullable<System.Threading.CancellationToken> -> unit

Public Sub Extract (packageStream As Stream, databaseName As String, applicationName As String, applicationVersion As Version, Optional applicationDescription As String = Nothing, Optional tables As IEnumerable(Of Tuple(Of String, String)) = Nothing, Optional extractOptions As DacExtractOptions = Nothing, Optional cancellationToken As Nullable(Of CancellationToken) = Nothing)

参数

packageStream: Stream

Stream 要向其写入包的包。

databaseName: String

源数据库的名称。

applicationName: String

DAC 应用程序的字符串标识符。

applicationVersion: Version

DAC 应用程序的版本。

applicationDescription: String

DAC 应用程序的可选字符串摘要。

tables: IEnumerable<Tuple<String,String>>

可选枚举，用于检索应为其导出数据的表集的枚举器。 Tuple对于枚举中的每个项，第一项指定表的架构，第二项指定表的基本标识符。

如果此参数的值为 null 引用，则不会导出任何数据。

extractOptions: DacExtractOptions

用于指定影响包提取行为的选项的可选 DacExtractOptions 实例。

cancellationToken: Nullable<CancellationToken>

可选 CancellationToken ，可用于指示应取消操作。使用此对象不能保证将取消操作。

例外

ArgumentException

如果 applicationName 为 null 引用或空字符串。

DacServicesException

如果在包提取过程中出现问题;或提供的流不适合写入包。

OperationCanceledException

CancellationToken如果请求了取消，并且可以取消该操作。
