语法
声明
Private Function GetConnection ( _
mode As SfcObjectQueryMode _
) As ISfcConnection Implements ISfcHasConnection.GetConnection
用法
Dim instance As IntegrationServices
Dim mode As SfcObjectQueryMode
Dim returnValue As ISfcConnection
returnValue = CType(instance, ISfcHasConnection).GetConnection(mode)
ISfcConnection ISfcHasConnection.GetConnection(
SfcObjectQueryMode mode
)
private:
virtual ISfcConnection^ GetConnection(
SfcObjectQueryMode mode
) sealed = ISfcHasConnection::GetConnection
private abstract GetConnection :
mode:SfcObjectQueryMode -> ISfcConnection
private override GetConnection :
mode:SfcObjectQueryMode -> ISfcConnection
JScript 支持使用显式接口实现,但不支持声明新显式接口实现。
参数
- mode
类型:Microsoft.SqlServer.Management.Sdk.Sfc.SfcObjectQueryMode
The mode of the connection.
返回值
类型:Microsoft.SqlServer.Management.Common.ISfcConnection
The connection to use, or nullnull 引用(在 Visual Basic 中为 Nothing) to use cache mode. Cache mode avoids connection and open data reader issues.
实现
ISfcHasConnection.GetConnection(SfcObjectQueryMode)
