html - MultipartMemoryStreamProvider and reading user data from MultiPart/Form Data -

i have file , user data being posted multipart/form data post method in apicontroller class. able read file without problems unable read user data.

i tried couple of things using model binding, passing individual fields method parameter in post method get: no mediatypeformatter available read object of type 'formdatacollection' content media type 'multipart/form-data'.

var provider = await request.content.readasmultipartasync(new multipartmemorystreamprovider()); foreach (var item in provider.contents) { var fieldname = item.headers.contentdisposition.name.trim('"'); if (item.headers.contentdisposition.filename == null) { var data = await item.readasstringasync(); if(fieldname = 'name')  name=data;  } else     filecontents = await item.readasbytearrayasync(); } 

thanks.

i had considered adding other post per comment, (as decided), separate question.

public async task<httpresponsemessage> post() {     if (!request.content.ismimemultipartcontent())         throw new httpresponseexception(httpstatuscode.unsupportedmediatype);      try     {         string root = httpcontext.current.server.mappath("~/app_data");          var provider = await request.content.readasmultipartasync(new multipartformdatastreamprovider(root));          // file data         foreach (multipartfiledata file in provider.filedata)         {             using (var ms = new memorystream())             {                 var diskfile = new filestream(file.localfilename, filemode.open);                  await diskfile.copytoasync(ms);                  var bytearray = ms.toarray();             }         }          // form data         foreach (var key in provider.formdata.allkeys)         {             var values = provider.formdata.getvalues(key);              if (values != null)             {                 foreach (var value in values)                 {                     console.writeline(value);                    }             }         }          return request.createresponse(httpstatuscode.created);     }     catch (exception ex)     {         return request.createerrorresponse(httpstatuscode.internalservererror, ex);     } }
