Can not Backups.No Error!

The Code:

Code Snippet

static void Main(string[] args)
{
try
{
SqlConnection Connection = new SqlConnection(@."Data Source=SUPER-9ZT4OE2OQ;Initial Catalog=DataBase;Persist Security Info=True;User ID=tj;password=tj");
Server server = new Server(new ServerConnection(Connection));
Backup bak = new Backup();
bak.Action = BackupActionType.Database;
bak.Database = "DataBase";

BackupDevice backupDevice = new BackupDevice(server, "Full_Backup");
backupDevice.PhysicalLocation = @."\\192.168.2.13\DatabaseBak\over.remoteBak";
backupDevice.BackupDeviceType = BackupDeviceType.Disk;

bak.Devices.AddDevice("Full_Backup", DeviceType.File);
bak.Incremental = false;
bak.SqlBackup(server);

}
catch (Exception)
{

throw;
}
}

Any help is highly appreciated

Thanks.

Try changing the line

bak.Devices.AddDevice(xxx)

to

bak.Devices.Add(xxx)

Here's the example (in VB.Net) from BOL:

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
'Define a Backup object variable.
Dim bk As New Backup
'Specify the type of backup, the description, the name, and the database to be backed up.
bk.Action = BackupActionType.Database
bk.Database = "AdventureWorks"
'Declare a BackupDeviceItem by supplying the backup device file name in the constructor, and the type of device is a file.
Dim bdi As BackupDeviceItem
bdi = New BackupDeviceItem("Test_Full_Backup1", DeviceType.File)
'Add the device to the Backup object.
bk.Devices.Add(bdi)
'Run SqlBackup to perform the full database backup on the instance of SQL Server.
bk.SqlBackup(srv)
