Restoring database using C sharp console application(SQl server 2008 R2)

Question

Hi All,
I want to take backup and restore database from one server to another through C sharp Console Application.
My Backup is working fine but restoring is not working and throwing below error:
An unhandled exception of type 'Microsoft.SqlServer.Management.Smo.FailedOperationException' occurred in Microsoft.SqlServer.SmoExtended.dll
Database name is fine while restoring.
Please give me some ideas in resolving this.
Thanks in advance.

Hi Olaf,
I used Replace database option.
My code is something like this.
  public void Restoredb(string serverName, string useraame, string password)
            ServerConnection conn;
            if (useraame == " ") // for Windows Authentication
                SqlConnection sqlCon = new SqlConnection(@"Data Source=" + serverName + @";Integrated Security=True;");
                conn = new ServerConnection(sqlCon);
            else // for Server Authentication
                conn = new ServerConnection(serverName, useraame, password);
            Server srv = new Server(conn);
            Database database = srv.Databases["db_Miller"];
            string dbPath = Path.Combine(database.PrimaryFilePath, "db_Miller.mdf");
            string logPath = Path.Combine(database.PrimaryFilePath, "db_Miller.ldf");
            Restore restore = new Restore();
            BackupDeviceItem deviceItem = new BackupDeviceItem(path, DeviceType.File);
            restore.Devices.Add(deviceItem);
            restore.Action = RestoreActionType.Database;
            restore.ReplaceDatabase = true;
            restore.NoRecovery = true;
            restore.SqlRestore(srv);  ------------- Getting error in this line.
            database = srv.Databases["db_Miller"];
            database.SetOnline();
            srv.Refresh();
            database.Refresh(); 
Thanks in advance.

Hi blrSvsTech,
You haven’t specified the restore destination database, please try the following codes:
public void Restoredb(string serverName, string useraame, string password)
ServerConnection conn;
if (useraame == " ") // for Windows Authentication
SqlConnection sqlCon = new SqlConnection(@"Data Source=" + serverName + @";Integrated Security=True;");
conn = new ServerConnection(sqlCon);
else // for Server Authentication
conn = new ServerConnection(serverName, useraame, password);
Server srv = new Server(conn);
Database database = srv.Databases["db_Miller"];
string dbPath = Path.Combine(database.PrimaryFilePath, "db_Miller.mdf");
string logPath = Path.Combine(database.PrimaryFilePath, "db_Miller.ldf");
Restore restore = new Restore();
BackupDeviceItem deviceItem = new BackupDeviceItem(path, DeviceType.File);
restore.Devices.Add(deviceItem);
restore.Action = RestoreActionType.Database;
restore.ReplaceDatabase = true;
restore.NoRecovery = true;
restore.database = srv.Databases["db_Miller"];
restore.SqlRestore(srv); ------------- Getting error in this line.
database = srv.Databases["db_Miller"];
database.SetOnline();
srv.Refresh();
database.Refresh();
If the issue occurs again, please post all the error message here for analysis.
