) : boolean

参数

srv
类型：Microsoft.SqlServer.Management.Smo.Server
A Server object that represents the instance of SQL Server that is targeted by the restore operation.

sqlVerifyAction
类型：Microsoft.SqlServer.Management.Smo.SqlVerifyAction
A SqlVerifyAction value that specifies the type of backup to verify.

示例

The following code example demonstrates how to create a backup of the AdventureWorks2012 database and verify that it is readable and complete without restoring.

Dim srv As Server = New Server("(local)")
Dim res As Restore = New Restore()
Dim backup As Backup = New Backup()

backup.Devices.AddDevice("C:\AdventureWorks2012Backup.bak", DeviceType.File)
backup.Database = "AdventureWorks2012"
backup.SqlBackup(srv)

res.Devices.AddDevice("C:\AdventureWorks2012Backup.bak", DeviceType.File)
res.Database = "AdventureWorks2012"
Console.WriteLine(res.SqlVerifyLatest(srv, SqlVerifyAction.VerifyFile).ToString())

Powershell

$srv = new-object Microsoft.SqlServer.Management.Smo.Server("(local)")
$res = new-object Microsoft.SqlServer.Management.Smo.Restore
$backup = new-object Microsoft.SqlServer.Management.Smo.Backup

$backup.Devices.AddDevice("C:\AdventureWorks2012Backup.bak", [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
$backup.Database = "AdventureWorks2012"
$backup.SqlBackup($srv)

$res.Devices.AddDevice("C:\AdventureWorks2012Backup.bak", [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
Write-Host $res.SqlVerifyLatest($srv, [Microsoft.SqlServer.Management.Smo.SqlVerifyAction]::VerifyFile)
