i am getting this error while compiling,when i add dependency injection then getting other error like,filefactory if this solved then getting customerfactory.
Actually i want to do custom code in my controller when user click -

     <?php

 namespace VendorModuleControllerAdminhtmlSendcredentials;

        use MagentoBackendAppActionContext;



    class Index extends  MagentoCustomerControllerAdminhtmlIndex

    {

        /**

         * Customer compare grid

         *

         * @return MagentoFrameworkViewResultLayout

         */

       public function __construct(

            Context $context,

            array $data =  

        ) {

            parent::__construct($context, $data);



        }



        public function execute()

        {

            $resultLayout = $this->_resultLayoutFactory->create();

            $getBlock = $resultLayout->getLayout()->createBlock("VendorModuleBlockAdminhtmlSendcredentials");

            echo $getBlock->getCustomCustomerId();



            die;  



        }

    }

Actually i need customer id in my custom controller.

You don't extend properly MagentoCustomerControllerAdminhtmlIndex to your class when try to call __construct . If you check the code of then you find a lot of parameters need __construct:MagentoCustomerControllerAdminhtmlIndex.

<?php





namespace VendorModuleControllerAdminhtmlSendcredentials;



class Index  extends  MagentoCustomerControllerAdminhtmlIndex

{



    public function __construct(

            MagentoBackendAppActionContext $context,

            MagentoFrameworkRegistry $coreRegistry, 

            MagentoFrameworkAppResponseHttpFileFactory $fileFactory,

            MagentoCustomerModelCustomerFactory $customerFactory,

            MagentoCustomerModelAddressFactory $addressFactory,

            MagentoCustomerModelMetadataFormFactory $formFactory, 

            MagentoNewsletterModelSubscriberFactory $subscriberFactory,

            MagentoCustomerHelperView $viewHelper, 

            MagentoFrameworkMathRandom $random, 

            MagentoCustomerApiCustomerRepositoryInterface $customerRepository,

            MagentoFrameworkApiExtensibleDataObjectConverter $extensibleDataObjectConverter,

            MagentoCustomerModelAddressMapper $addressMapper,

            MagentoCustomerApiAccountManagementInterface $customerAccountManagement,

            MagentoCustomerApiAddressRepositoryInterface $addressRepository,

            MagentoCustomerApiDataCustomerInterfaceFactory $customerDataFactory,

            MagentoCustomerApiDataAddressInterfaceFactory $addressDataFactory,

            MagentoCustomerModelCustomerMapper $customerMapper,

            MagentoFrameworkReflectionDataObjectProcessor $dataObjectProcessor,

            MagentoFrameworkApiDataObjectHelper $dataObjectHelper,

            MagentoFrameworkDataObjectFactory $objectFactory,

            MagentoFrameworkViewLayoutFactory $layoutFactory,

            MagentoFrameworkViewResultLayoutFactory $resultLayoutFactory,

            MagentoFrameworkViewResultPageFactory $resultPageFactory,

            MagentoBackendModelViewResultForwardFactory $resultForwardFactory,

            MagentoFrameworkControllerResultJsonFactory $resultJsonFactory) 

            {

        parent::__construct($context, $coreRegistry, $fileFactory, $customerFactory, $addressFactory, $formFactory, $subscriberFactory, $viewHelper, $random, $customerRepository, $extensibleDataObjectConverter, $addressMapper, $customerAccountManagement, $addressRepository, $customerDataFactory, $addressDataFactory, $customerMapper, $dataObjectProcessor, $dataObjectHelper, $objectFactory, $layoutFactory, $resultLayoutFactory, $resultPageFactory, $resultForwardFactory, $resultJsonFactory);

    }



    public function execute() {



    }



}

No of parameters at __construct:MagentoCustomerControllerAdminhtmlIndex is 25 ,https://github.com/magento/magento2/blob/2.3-develop/app/code/Magento/Customer/Controller/Adminhtml/Index.php#L201-L225

but your extends class's has two parameters parent::__construct($context, $data) .So no of parameters should be same for extends __construct and original one.

Remove the constructor method from your class.

the original class MagentoCustomerControllerAdminhtmlIndex has a constructor with way more parameters than you provided in your code.
