asp.net - Model mismatch error when posting form -

i working on simple image upload site in users have ability post comments on images uploaded site, whenever posting comment given error :

the model item passed dictionary of type '<>f__anonymoustype1`1[system.int32]', dictionary requires model item of type 'silkmeme.models.meme'.

i know has model being defined @ top of view being different 1 sending post request i'm not entirely sure how fix it

view

@model silkmeme.models.meme .... @using (html.beginform("comment", "memes", new { id = model.silkid })) {     <label for="thought">thoughts?</label>     <input type="text" name="thought"/>     <label for="rating">rating?</label>     <input name="rating" type="range" min="0" max="10" step="1" />      <input type="submit" value="post thoughts" /> } <div class="thoughts">     @foreach (var c in viewbag.thoughts)     {         <p>- @c.thoughtwords , @c.thoughtrating / 10 meme</p>     } </div> 

controller

public actionresult details(int? id) {     var thoughts = comment in db.thoughts comment.silkid == id select comment;     viewbag.thoughts = thoughts;     if (id == null)     {         return new httpstatuscoderesult(httpstatuscode.badrequest);     }     meme meme = db.memes.find(id);     if (meme == null)     {         return httpnotfound();     }     return view(meme); }  [httppost] public actionresult comment(int id) {     int thoughtid = (from m in db.thoughts select m).orderbydescending(e => e.thoughtid).firstordefault().thoughtid + 1;     if (request["thought"].tostring() != "")     {         thought thought = new thought()         {             thoughtid = thoughtid,             silkid = id,             meme = db.memes.find(id),             thoughtwords = request["thought"],             thoughtrating = int32.parse(request["rating"])         };         db.thoughts.add(thought);     }     return view("details", new { id = id }); } 

this line.

return view("details", new { id = id }); 

it passing anonymous object id property view typed meme type , expects object of meme class.

if save data successfully, ideally,you should redirect action (following prg pattern)

[httppost] public actionresult comment(int id) {     int thoughtid = (from m in db.thoughts select m)                       .orderbydescending(e => e.thoughtid).firstordefault().thoughtid + 1;     if (request["thought"].tostring() != "")     {         thought thought = new thought()         {             thoughtid = thoughtid,             silkid = id,             meme = db.memes.find(id),             thoughtwords = request["thought"],             thoughtrating = int32.parse(request["rating"])         };         db.thoughts.add(thought);         db.savechanges();     }     return redirecttoaction("details", new { id=id }); } 

also, recommend using mvc modelbinding read submitted form data. find ton of examples on stackoverflow that. when using modelbinding, can return posted view model view (with error message if needed) , validationsummary /validationmessgefor helper methods can show error message user needed.
