How to restore SQL Server database through C# code

Question

I try to restore the database like this:

SQL = @\"RESTORE DATABASE MyDataBase TO DISK=\'d:\\MyDATA.BAK\'\";
                Cmd = new SqlCommand(SQL, Conn);
         


        

Answer 1

I prefer to use SMO to restore a backup:

Microsoft.SqlServer.Management.Smo.Server smoServer = 
     new Server(new ServerConnection(server));

Database db = smoServer.Databases['MyDataBase'];
string dbPath = Path.Combine(db.PrimaryFilePath, 'MyDataBase.mdf');
string logPath = Path.Combine(db.PrimaryFilePath, 'MyDataBase_Log.ldf');
Restore restore = new Restore();
BackupDeviceItem deviceItem = 
    new BackupDeviceItem('d:\MyDATA.BAK', DeviceType.File);
restore.Devices.Add(deviceItem);
restore.Database = backupDatabaseTo;
restore.FileNumber = restoreFileNumber;
restore.Action = RestoreActionType.Database;
restore.ReplaceDatabase = true;
restore.SqlRestore(smoServer);

db = smoServer.Databases['MyDataBase'];
db.SetOnline();
smoServer.Refresh();
db.Refresh();

You'll need references to Microsoft.SqlServer.Smo, Microsoft.SqlServer.SmoExtended, and Microsoft.SqlServer.Management.Sdk.Sfc
