    public ActionResult listMyGroups(int? id=1)
    {
        if(TempData["id"]!=null)
        id = (int)TempData["id"];
        //分组列表数据
        var groups = db.PrivateGroups.Where(a=>a.OwnerId==id).ToList();
        //未分组好友个数
        var unGroupCount = db.FriendRelations.Where(a=>a.UserId==id&&a.GroupId.HasValue==false).Count();
        //好友总数
        var totalCount = db.FriendRelations.Where(a=>a.UserId==id).Count();
        ViewBag.id = id;
        ViewBag.Groups = groups;
        ViewBag.UnGroupCount = unGroupCount;
        ViewBag.totalCount = totalCount;
        return PartialView("MyGroupsList");
    }

            那个Addgroup action 第一次点添加分组，它就执行了两遍，第二次就执行四遍，第三次执行八遍，成双倍的执行，为什么会这样？

Answer 1

是不是MyGroupsList 页面也调用的listMyGroups函数

Answer 2

return RedirectToAction("listMyGroups");
->
return PartialView("listMyGroups");
