Magento 2 pragmatically set storeview

Question

I am using Magento 2.1.7 and want to programatically load a specific store view on my multi-site based on what country a user is in when they arrive on our website. However in Magento 2 I am not sure how to do this. I tried doing the below. However it does not seem to work?? Any suggestions?

I have the below code

//lets redirect user to a country specific store based on where they are from
$myipaddressis = $_SERVER['REMOTE_ADDR'];
$mycountryis = geoip_country_code_by_name($_SERVER['REMOTE_ADDR']);

if($mycountryis =='DE')
  {
    //$this->_objectManager->get('Magento\Store\Model\StoreManagerInterface')->setCurrentStore(1);
  }
if($mycountryis =='GB')
  {
    //$this->_objectManager->get('Magento\Store\Model\StoreManagerInterface')->setCurrentStore(2);
  }

Add this code in index.php

$myipaddressis = $_SERVER['REMOTE_ADDR'];
$mycountryis = geoip_country_code_by_name($_SERVER['REMOTE_ADDR']);    
$store='your_default_store_code';
if($mycountryis =='DE')
  {
   $store='your de store code';
  }
$params = $_SERVER;
$params[\Magento\Store\Model\StoreManager::PARAM_RUN_CODE] = $store;
$params[\Magento\Store\Model\StoreManager::PARAM_RUN_TYPE] = 'store';
$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $params);
$app = $bootstrap->createApplication('Magento\Framework\App\Http');
$bootstrap->run($app);
