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);
