asp.net mvc - MVC Pass element id from view to controller -

foreach (var item in model) {     using (html.beginform("previewimage", "music", formmethod.post, new { @enctype = "multipart/form-data" }))     {         @html.antiforgerytoken()          <input type="file" class="upload-image" id="upload-image-file_@item.id" name="file" accept="image/*">         <button class="btn btn-default" id="bt_@item.id" style="display: none" type="submit"></button>     } } 

how pass file id controller?

under assumption want pass path of image uploaded - inside of controller, use following:

if (request.files.count > 0) {          var file = request.files[0];           if (file != null && file.contentlength > 0)          {             var filename = path.getfilename(file.filename);             var serverpath = path.combine(server.mappath("~/images/"), filename);             file.saveas(serverpath);           } } 

under assumption talking @item.id variable appending id, add @item.id here:

using (html.beginform("previewimage", "music", formmethod.post, new { @enctype = "multipart/form-data", @itemid = @item.id })) 

and make corresponding changes controller.
