i write this code in HttpGet Index Control :
        public ActionResult Index(int id)
		var model=_db.nezam.tolist();
		return view(model);

and in view i have a form :
<input type="text" name="cap" />
<input type="submit"  value="OK" />

in httpost i write :
    public ActionResult Index(string cap)
          string st=HttpContext.Session["captcha"].ToString();
          if (cap == st)
              return Content("true");
          return View(?);

when i run my project and click on ok button give me this error :
System.NullReferenceException: Object reference not set to an instance of an object.

it is true because i dont sent any model to view , but i dont know how get model from html.beginform and next send it to view again ,=== return View(?)?????

You REALLY need to pick up book on MAC. There's plenty more concepts you're missing on top of just getting a form to post.
