You can change signature of action method to public ActionResult MyMethod() and return FileResult when ModelState.IsValid==true and ViewResult when ModelState.IsValid==false
您可以将action方法的签名更改为公共ActionResult MyMethod(),并在ModelState.IsValid == true时返回FileResult,在ModelState.IsValid == false时返回ViewResult
