How to get size of HttpPostedFileBase file

I have a function that has a parameter of type HttpPostedFileBase and I'm getting the file's name using (Path.GetFileName):

public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments)
       {
           foreach (var file in attachments)
           {

               var fileName = Path.GetFileName(fil开发者_如何学Goe.FileName);
}
}

How can I get the file size??

The ContentLength property on the HttpPostedFileBase class contains the number of bytes in the posted file

int byteCount = file.ContentLength;
