c# - Controller action not grabbing file from view when attempting to upload -

i trying upload .csv file sql database, controller action not seem grabbing file @ all. check out code, must missing piece:

view:

@using (html.beginform("uploadvalidationtable", "home", formmethod.post)) { <table style="margin-top: 150px;">     <tr>         <td>             <label for="csvfile">filename:</label>         </td>         <td>             <input type="file" name="csvfile" id="csvfile"/>         </td>         <td><input type="submit" value="upload"/></td>     </tr> </table> } 

controller:

[httppost]     public jsonresult uploadvalidationtable(httppostedfilebase csvfile)     {         var inputfiledescription = new csvfiledescription         {              separatorchar = ',',              firstlinehascolumnnames = true         };         var cc = new csvcontext();         var filepath = uploadfile(csvfile.inputstream);         var model = cc.read<outstandingcreditcsv>(filepath, inputfiledescription);          try         {             var entity = new outstandingcreditcsv();              foreach (var item in model)             {                 entity.ponumber = item.ponumber;                 entity.creditinvoicedate = item.creditinvoicedate;                 entity.creditinvoicenumber = item.creditinvoicenumber;                 entity.creditinvoiceamount = item.creditinvoiceamount;              }         }         catch(linqtocsvexception ex)         {          }          return json(model, "text/json");     } 

csvfile appearing null, no clue going on since named in view , have post method surrounding it. makes down until var filepath = uploadfile(csvfile.inputstream); , breaks since method trying pass null value. thanks!

i came across when trying upload files db using mvc while back, using scaffolded views (so passed object form), might bit different.

in html.beginform() call you'll need add attribute enctype="multipart/form-data"

@using (html.beginform("uploadvalidationtable", "home", formmethod.post, new {enctype="multipart/form-data"}))
