I am trying to get order collection by order id in Magento 2.

Here is my code:

$objectManager = MagentoFrameworkAppObjectManager::getInstance();

$orders = $objectManager->create('MagentoSalesModelOrder')->getCollection()->load($oid);



echo $custLastName= $orders->getCustomerLastname();

But its is giving fatal error:

 Call to undefined method MagentoSalesModelResourceModelOrderCollection::getCustomerLastname()

Just Remove getCollection :-

$objectManager = MagentoFrameworkAppObjectManager::getInstance();

$orders = $objectManager->create('MagentoSalesModelOrder')->load($oid);



echo $custLastName= $orders->getCustomerLastname();

The Following code will easily get Customer details, Billing, Shipping and order totals

  $orderId = 1222;

  $objectManager = MagentoFrameworkAppObjectManager::getInstance(); 

  $order = $objectManager->create('MagentoSalesModelOrderRepository')->get($orderId);



  /*get customer details*/



  $custLastName= $orders->getCustomerLastname();

  $custFirsrName= $orders->getCustomerFirstname();

  $ipaddress=$order->getRemoteIp();

  $customer_email=$order->getCustomerEmail();

  $customerid=$order->getCustomerId();



  /* get Billing details */  

  $billingaddress=$order->getBillingAddress();

  $billingcity=$billingaddress->getCity();      

  $billingstreet=$billingaddress->getStreet();

  $billingpostcode=$billingaddress->getPostcode();

  $billingtelephone=$billingaddress->getTelephone();

  $billingstate_code=$billingaddress->getRegionCode();



  /* get shipping details */



  $shippingaddress=$order->getShippingAddress();        

  $shippingcity=$shippingaddress->getCity();

  $shippingstreet=$shippingaddress->getStreet();

  $shippingpostcode=$shippingaddress->getPostcode();      

  $shippingtelephone=$shippingaddress->getTelephone();

  $shippingstate_code=$shippingaddress->getRegionCode();



 /* get  total */



  $tax_amount=$order->getTaxAmount();

  $total=$order->getGrandTotal();

try with

$orders = $objectManager->create('MagentoSalesModelResourceModelOrderCollectionFactory');



foreach ($orders as $order){

    echo $order->getCustomerLastname();

    echo $order->getData($id);

}
