Question

我想知道是否有人可以在这里帮助我。我想给出这样的日期格式："MM/dd/yyyy" 我知道查询字符串中的所有格式都应为int或string。这是我的url.action：

@Html.PagedListPager(Model, page => Url.Action("Index", new 
{ 
  page, 
  creationDate = ViewBag.Date.ToString(),  
  sortOrder = ViewBag.CurrentSort, 
  AccountIdFilter = ViewBag.AccountIdFilter 
}))

问题出在creationDate = ViewBag.Date.ToString()上。这将转换为字符串，但不是MM/dd/yyyy格式。这是我的控制器：

  public ActionResult Index(string accountIdFilter,DateTime? creationDate, int page=1, Sort sortOrder =Sort.Descending)        
        {
            int take = 2;
            DateTime date;
            ViewBag.CurrentSort = sortOrder;
            ViewBag.NameSortParm = sortOrder == Sort.Descending ? Sort.Assending : Sort.Descending;
            ViewBag.AccountIdFilter = accountIdFilter;
            if (!creationDate.HasValue)
            {
                 date = DateTime.ParseExact("2020-05-08", "yyyy-MM-dd",
                                                      System.Globalization.CultureInfo.InvariantCulture);
            }
            else
            {

                date = DateTime.ParseExact(creationDate.ToString(), "MM/dd/yyyy",
                                       System.Globalization.CultureInfo.InvariantCulture);
            }
            ViewBag.Date = date;
            BankDepositHistoryListDTO data;
            try
            {                
                 data = BankDepositHistoryServices.GetAllByPagination(sortOrder, accountIdFilter, take, creationDate, page);                
            }
            catch (Exception ex)
            {
                logger.Error(ex.ToString());
                data = BankDepositHistoryServices.GetAllByPagination(sortOrder, accountIdFilter, take, creationDate, 1);
                page = 1;
            }
            var result = data.BankDepositHistoriyItems;
            int count = data.Count;
            var resultPagedList = new StaticPagedList<BankDepositHistoryDTO>(result, page, take, count);
            return View(resultPagedList);            
        }

问题在这里：

 else
            {

                date = DateTime.ParseExact(creationDate.ToString(), "MM/dd/yyyy",
                                       System.Globalization.CultureInfo.InvariantCulture);
            }

那一行我遇到了这个异常：String was not recognized as a valid DateTime. creationDate.ToString()的输出为"5/8/2020 12:00:00 AM"。所以我该怎么做？非常感谢
