powershell - Restore-SqlDatabase cmdlet 中的 RelocateFile 属性存在问题

Question

我尝试使用 Restore-SqlDatabase cmdlet 还原数据库。我需要重新定位文件，但出现以下错误

Restore-SqlDatabase : Cannot bind parameter 'RelocateFile'. Cannot convert the 
"Microsoft.SqlServer.Management.Smo.RelocateFile" value of type 
"Microsoft.SqlServer.Management.Smo.RelocateFile" to type 
"Microsoft.SqlServer.Management.Smo.RelocateFile".
At line:25 char:108
+ ... e -RelocateFil $RelocateData
+                    ~~~~~~~~~~~~~
+ CategoryInfo          : InvalidArgument: (:) [Restore-SqlDatabase], ParameterBindingException
+ FullyQualifiedErrorId CannotConvertArgumentNoMessage,Microsoft.SqlServer.Management.PowerShell.RestoreSqlDatabaseCommand

我的 powershell 代码如下所示

$RelocateData = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile("MyDB_Data", "c:\data\MySQLServerMyDB.mdf") 
$RelocateLog = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile("MyDB_Log", "c:\data\MySQLServerMyDB.ldf") 
$file = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile($RelocateData,$RelocateLog) 
$myarr=@($RelocateData,$RelocateLog)
Restore-SqlDatabase -ServerInstance DEV\DEMO -Database "test" -BackupFile $backupfile -RelocateFile $myarr

Answer 1

您可以通过与版本无关的方式执行此操作:

$sqlServerSnapinVersion = (Get-Command Restore-SqlDatabase).ImplementingType.Assembly.GetName().Version.ToString()
$assemblySqlServerSmoExtendedFullName = "Microsoft.SqlServer.SmoExtended, Version=$sqlServerSnapinVersion, Culture=neutral, PublicKeyToken=89845dcd8080cc91"

$RelocateData = New-Object "Microsoft.SqlServer.Management.Smo.RelocateFile, $assemblySqlServerSmoExtendedFullName"('MyDB_Data', 'c:\data\MySQLServerMyDB.mdf')
$RelocateLog = New-Object "Microsoft.SqlServer.Management.Smo.RelocateFile, $assemblySqlServerSmoExtendedFullName"('MyDB_Log', 'c:\data\MySQLServerMyDB.ldf')
$myarr=@($RelocateData,$RelocateLog)
Restore-SqlDatabase -ServerInstance DEV\DEMO -Database "test" -BackupFile $backupfile -RelocateFile $myarr
