please tell me more needs done. also, how generate link download file.

first, action of form points ~/views/home/_saveupdate while should /home/index based on post-action. second, make sure have created upload folder inside app_data folder. should take care of upload problem.

view:

<form action="/home/index" method="post" enctype="multipart/form-data">     <label for="file1">filename:</label>     <input type="file" name="files" id="file1" />     <label for="file2">filename:</label>     <input type="file" name="files" id="file2" />     <input type="submit"  /> </form> 

if want display download links uploaded files, should store images in different folder app_data. app_data folder not directly accessible due security reasons.

a example show files in directory can found here
