Thought you said you were using the MVC FileUpload class - this looks like angular (ng-file-upload) ?

>>>Hi everybody,
>>>
>>>I am wondering if anyone implemented the File Uploader with the ASP.NET MVC and Windows API. I'm having problems :(
>>>
>>>My last attempt is the following:
>>>
>>>I created this class
>>>
>>>

>>> public class FileUploadResult
>>>    {
>>>        public String FileName { get; set; }
>>>        public String Key { get; set; }
>>>        public int PercentComplete { get; set; }
>>>        public HttpPostedFile Content { get; set; }
>>>        
>>>        public string Type { get; set; }
>>>    }

>>>
>>>and in my JavaScript file I attempt to save file as the Content property. So far so good.
>>>
>>>However, I am unable to post that info using my model which is the following:
>>>
>>>

>>> public class EditMessageViewModel
>>>    {
>>>        public short FormType { get; set; }
>>>        public int MessageId { get; set; } // MessageID (Primary key)
>>>        //public byte ReciptType { get; set; } // ReciptType. Type of recipient.  1=Guest.
>>>        //public decimal ReciptId { get; set; } // ReciptID. ID of the recipient.  I.e. if recipient type is a guest, then guest_no.
>>>        public string Body { get; set; } // Body
>>>  //      public System.DateTime DateTime { get; set; } // date_time
>>>  //      public System.Nullable<System.DateTime> Delivered { get; set; } // delivered
>>>        public System.DateTime Expires { get; set; } // expires
>>>
>>>        public string MsgFrom { get; set; }
>>>
>>>        public string Subject { get; set; }
>>>
>>>        public List<FileUploadResult> Attachments { get; set; }
>>>
>>>        public List<GuestsList> Recipients { get; set; }
>>>    }

>>>
>>>However, when I try to post I'm getting the 'Bad Request' right away, so apparently I can not post such model back.
>>>
>>>So, how exactly should I post both my model and the files I'm trying to upload?
>>
>>Multipart form data can contain a mix of files and (for example) json objects. But I haven't used the MVC FileUpoader and don't know whether you can add additional parts on the client side before posting.
>>
>>In any case I don't see how you can create a valid FileUploadResult in javascript since it contains a HttpPostedFile instance and one of it's properties is a .NET stream.......
