The following code example demonstrates how to create a backup, associate it with an instance of the restore class, and use the ReadBackupHeader method to display information about the restore media contents.
VB
Dim srv As Server = New Server()
Dim res As Restore = New Restore()
Dim backup As Backup = New Backup()
Dim dt As DataTable
backup.Devices.AddDevice("C:\AdventureWorks2012Backup.bak", DeviceType.File)
backup.Database = "AdventureWorks2012"
backup.Action = BackupActionType.Database
backup.Initialize = True
backup.SqlBackup(srv)
res.Devices.AddDevice("C:\AdventureWorks2012Backup.BAK", DeviceType.File)
dt = res.ReadBackupHeader(srv)
For Each r As DataRow In dt.Rows
For Each c As DataColumn In dt.Columns
Console.WriteLine(c.ToString + " = " + r(c).ToString())
Next

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"

foreach($r in $dt.Rows)
{
foreach ($c in $dt.Columns)
