asp.net mvc与jquery ajax cal HttpPostedFileBase文件获取空值

**Jquery Ajax call sending data to controller** $("#btncareerssubmimt").click(function () { var Name = $("#txtname").val(); var file = $("#fileresume").val(); $.ajax({ type: "POST", url: '/Footer/sendmail', data: { Name: Name ,file: file }, success: function () { $("#simplecareers").html('
Your Request Submitted Successfully
'); }, error: function (XMLHttpRequest, textStatus, errorThrown) { $("#simple-msg").html('
"fail"
'); } }); }  
 在aboveo ajax cal iam正确获取名称和文件路径，但是当我们传递给控制器​​只获取名称但文件路径变为null我的Html视图 
   input type="file" name="file" id="fileresume" value=""/>  This is my controller [HttpPost] public ActionResult sendmail(string Name ,HttpPostedFileBase fileresume) { }
