[HttpPost]
public ActionResult Page2(FormCollection objCollection)
{
HttpPostedFileBase file = Request.Files[0];
}

希望这可以帮助
更新：
The stream that you get from your HTTP call is read-only sequential
(non-seekable) and the FileStream is read/write seekable. You will
need first to read the entire stream from the HTTP call into a byte
array,then create the FileStream from that array.
摘自here
// Read bytes from http input stream BinaryReader b = new BinaryReader(file.InputStream); byte[] binData = b.ReadBytes(file.InputStream.Length); string result = System.Text.Encoding.UTF8.GetString(binData);
