c# - Automated file upload with additional model -

i have following mvc 4 action

[acceptverbs(httpverbs.post)] public actionresult sendattachment(someviewmodel model, httppostedfilebase attachment) {     // implementation goes here } 

now want upload file console app controller action using httpwebrequest api can't figure out how set both model , file data in post, matches controller.

any hints on that?

i made changes function (upload files httpwebrequest (multipart/form-data)) problem. worked me. try this:

server side

    [httppost]     public actionresult sendattachment(someviewmodel model, httppostedfilebase attachment)     {         return view();     }      public class someviewmodel       {         public int id { get; set; }         public string name { get; set; }     } 

in console app:

static void main(string[] args)     {         uploaddata(             "http://dissertation.lan/home/sendattachment",             new namevaluecollection()             {                  {"attachment", @"c:\users\_____\desktop\yourfile.xltx"}             },             new namevaluecollection()              {                 {"id", "2"},                 {"name","man"}             });     }      public static void uploaddata(string url, namevaluecollection files, namevaluecollection nvc)     {         string boundary = "----------------------------" + datetime.now.ticks.tostring("x");          httpwebrequest httpwebrequest2 = (httpwebrequest)webrequest.create(url);         httpwebrequest2.contenttype = "multipart/form-data; boundary=" + boundary;         httpwebrequest2.method = "post";         httpwebrequest2.keepalive = true;         httpwebrequest2.credentials = system.net.credentialcache.defaultcredentials;          stream memstream = new system.io.memorystream();          byte[] boundarybytes = system.text.encoding.ascii.getbytes("\r\n--" +         boundary + "\r\n");          string formdatatemplate = "\r\n--" + boundary +         "\r\ncontent-disposition: form-data; name=\"{0}\";\r\n\r\n{1}";          foreach (string key in nvc.keys)         {             string formitem = string.format(formdatatemplate, key, nvc[key]);             byte[] formitembytes = system.text.encoding.utf8.getbytes(formitem);             memstream.write(formitembytes, 0, formitembytes.length);         }          memstream.write(boundarybytes, 0, boundarybytes.length);          string headertemplate = "content-disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n content-type: application/octet-stream\r\n\r\n";          foreach (string key in files.keys)         {             string header = string.format(headertemplate, key, files[key]);             byte[] headerbytes = system.text.encoding.utf8.getbytes(header);             memstream.write(headerbytes, 0, headerbytes.length);              filestream filestream = new filestream(files[key], filemode.open,             fileaccess.read);             byte[] buffer = new byte[1024];             int bytesread = 0;              while ((bytesread = filestream.read(buffer, 0, buffer.length)) != 0)             {                 memstream.write(buffer, 0, bytesread);             }              memstream.write(boundarybytes, 0, boundarybytes.length);              filestream.close();         }          httpwebrequest2.contentlength = memstream.length;          stream requeststream = httpwebrequest2.getrequeststream();          memstream.position = 0;         byte[] tempbuffer = new byte[memstream.length];         memstream.read(tempbuffer, 0, tempbuffer.length);         memstream.close();         requeststream.write(tempbuffer, 0, tempbuffer.length);         requeststream.close();          webresponse webresponse2 = httpwebrequest2.getresponse();          stream stream2 = webresponse2.getresponsestream();         streamreader reader2 = new streamreader(stream2);          console.write(reader2.readtoend());          webresponse2.close();         httpwebrequest2 = null;         webresponse2 = null;     }
