Read both key values and files from multipart from data post request in ASP.NET WebAPI -

i have endpoint needs accept file upload , other information client request. following code can upload file can't seem figure out how read other info.

i make test request postman following form data:

image -- myimage.jpg -- of type file

email -- a@b.com -- of type text

the backend code looks this:

[httppost] public async task<httpresponsemessage> sharephoto() {        try     {          var provider = new multipartmemorystreamprovider();          var data  = await request.content.readasmultipartasync(provider);           // how image succesfully passing emailservice          var item = (streamcontent)provider.contents[0];          using (var stream = new memorystream())          {              await item.copytoasync(stream);              string emailaddress;              emailservice.sendsharedphoto(emailaddress, stream);              return request.createresponse();          }                     }      catch      {         // stuff      } } 

in example able access provider.contents[1] can't seem able value emailaddress. i'm thinking may possible use same trick await item.copytoasync(stream) image upload, i'm hoping can simpler solution that. ideas?
