【问题描述】：
所以我已经尝试了超过 24 小时并且没有从哪里发现 ERROR ，试图一步一步地遵循 Symfony DOC How to Handle File Uploads with Doctrine 然后当它点击我的页面表单中的上传按钮时我得到了这个错误：
Catchable Fatal Error: Argument 1 passed to Custom\CMSBundle\Entity\Page::setFile() must be an instance of Custom\CMSBundle\Entity\UploadedFile, instance of Symfony\Component\HttpFoundation\File\UploadedFile given, called in C:\Users\THINK\Desktop\PHP-Symfony2---Build_a_CMS-master\vendor\symfony\symfony\src\Symfony\Component\PropertyAccess\PropertyAccessor.php on line 442 and defined
