C# IntegrationServices APIs with Package deployment

Is it possible to Run package.excute using C# IntegrationServices APIs just like Dts.Execute API? I have deployed package deployment (and not project deployment). All code samples shows samples with project deployment like one below.

SqlConnection ssisConnection = new SqlConnection(@"Data Source=.\SQL2012;Initial Catalog=master;Integrated Security=SSPI;");

            // SSIS server object with connection
            IntegrationServices ssisServer = new IntegrationServices(ssisConnection);

            // The reference to the package which you want to execute
            PackageInfo ssisPackage = ssisServer.Catalogs["SSISDB"].Folders["MasterChild"].Projects["MasterChildPackages"].Packages["master.dtsx"];

            // Add execution parameter to override the default asynchronized execution. If you leave this out the package is executed asynchronized
            Collection<PackageInfo.ExecutionValueParameterSet> executionParameter = new Collection<PackageInfo.ExecutionValueParameterSet>();
            executionParameter.Add(new PackageInfo.ExecutionValueParameterSet { ObjectType = 50, ParameterName = "SYNCHRONIZED", ParameterValue = 1 });

            // Get the identifier of the execution to get the log
            long executionIdentifier = ssisPackage.Execute(false, null, executionParameter);

            // Loop through the log and add the messages to the listbox
            foreach (OperationMessage message in ssisServer.Catalogs["SSISDB"].Executions[executionIdentifier].Messages)
            {
                SSISMessagesListBox.Items.Add(message.MessageType.ToString() + ": " + message.Message);
            }

Thanks!
