            con.Open();

            SqlCommand cmd = new SqlCommand("INSERT INTO UploadFiles (FileData, ContentType) VALUES (@filedata, @ContentType)", con);

            cmd.CommandType = System.Data.CommandType.Text;

using binary reader

 Stream fs = fileUpload1.PostedFile.InputStream;

        BinaryReader br = new BinaryReader(fs);

        

        Byte[] bytes = br.ReadBytes((int)fs.Length);

  Stream fs = fileUpload1.PostedFile.InputStream;

 Byte[] bytes = br.ReadBytes((int)fs.Length);
