SMO Restore Failed/Cannot Open Backup Device Error - winforms

Question

I got an error while I'm trying to restore a SQL Server 2008 R2 database:
Restore failed for Server 'KIMO-PC'.
Code used:
Server myServer = new Server("KIMO-PC");
Database myDatabase = new Database(myServer, "POS");
Restore restoreDB = new Restore();
restoreDB.Database = myDatabase.Name;
restoreDB.Action = RestoreActionType.Database;
restoreDB.Devices.AddDevice(FileName, DeviceType.File);
restoreDB.ReplaceDatabase = false;
restoreDB.NoRecovery = true;
restoreDB.PercentComplete += CompletionStatusInPercent;
restoreDB.Complete += Restore_Completed;
restoreDB.SqlRestore(myServer);
and here is the exception details
Microsoft.SqlServer.Management.Smo.FailedOperationException was unhandled HelpLink=http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.50.1600.1+((KJ_RTM).100402-1540+)&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=Restore+Server&LinkId=20476 Message=Restore failed for Server 'KIMO-PC'.

Answer 1

Take a look at the stack trace inner exception:
Cannot open backup device 'C:\Users\kimo\Desktop\POS.bak'. Operating
system error 5
Most likely, the SQL Server does not have rights to view files in kimo\Desktop. Move the backup to a different folder like c:\temp and try it again.

Answer 2

Try this:
Database currentDb = srvsql.Databases["dbname"];// get the current database
if (currentDb != null)
{
Connection.ChangeDatabase("dbname");
//Stop all processes running on the DataBase database
server.KillAllProcesses("dbname ");
}
