Question

提前感谢您，这就是问题所在：我的表单中有一个Action to Main Controller专门用于索引。第一次进行查询并返回

"http://localhost:59761/Main/Index"

但是当我做第二次下拉选择时，它会返回

"http://localhost:59761/Main/Main/Index"

（返回控制器两次）。基本上我想要的是返回索引。

这是视图：

<form  method="post" action="Main/Index">
     <select name="week"  id="week">
            <option value=1>Week 1</option>
            <option value=2>Week 2</option>
            <option value=3>Week 3</option>
            <option value=4>Week 4</option>
            <option value=5>Week 5</option>
     </select>  
  <input type="submit" value="Search" id="Search"/>     
  </form>

控制器：

public ActionResult Index(int? week )
    {
        if (week != null)
        {
            var quest = (from q in db.weekly_games
                         where q.week_um == week
                         select q).ToList();
            return View(quest);
        }

        return View(db.weekly_games.ToList());

    }

这是RouteConfig：

routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Main", action = "Index", id = UrlParameter.Optional }

使用Html.Beginform html辅助方法，而不是在表单中对操作值进行硬编码。它将为表单的action属性呈现正确的值。

@using(Html.BeginForm("Index","Main"))
{
     <select name="week"  id="week">
            <option value=1>Week 1</option>
            <option value=2>Week 2</option>
            <option value=3>Week 3</option>
            <option value=4>Week 4</option>
            <option value=5>Week 5</option>
     </select>  
  <input type="submit" value="Search" id="Search"/>     
}
