需要将sql转换为linq等待响应

Question

var clientsdata = (from c in _dataContext.Clients
                               join ao in _dataContext.AccountOwners on c.AccountOwnerID equals ao.AccountOwnerID
                               join at in _dataContext.AccountTypes on c.AccountTypeID equals at.AccountTypeID
                               where c.IsActive == true && (c.IsDeleted == false || c.IsDeleted == null) && c.AccountExpiryDate > DateTime.Now && (GetdayValue(c.AccountExpiryDate) >= getMondayValue(c.AccountExpiryDate, true) && GetdayValue(c.AccountExpiryDate) <= getMondayValue(c.AccountExpiryDate, false))
                               select new EntClient
                               {
                                   Clientid = c.ClientID,
                                   ClientEmail = c.ClientEmail,
                                   ClientName = c.ClientName,
                                   AccountOwnerName = ao.AccountOwnerName,
                                   AccountOwnerID = ao.AccountOwnerID,
                                   AccountTypeID = at.AccountTypeID,
                                   AccountExpiryDate = c.AccountExpiryDate,
                                   CurrentPlanPricePerMonth = at.PricePerMonth
                                   //acc
                               }).ToList();

        public DateTime getMondayValue(DateTime? dayVal, bool isLastMonday)
        {
            DateTime temp = DateTime.Now;

            if (dayVal == null)
                return temp;

            temp = dayVal.Value;

            if (isLastMonday)
                temp = DateTime.Now.AddDays(-(DateTime.Today.DayOfWeek - DayOfWeek.Monday - 7));
            else
                temp = DateTime.Now.AddDays(-(int)DateTime.Now.DayOfWeek).AddDays((int)DayOfWeek.Monday);
            return temp;
        }
        public DateTime GetdayValue(DateTime? dayVal)
        {
            DateTime temp = DateTime.Now;
            if (dayVal == null)
                return temp;
            temp = dayVal.Value;
            temp = new DateTime(DateTime.Now.Year, DateTime.Now.Month, temp.Day);
            return temp;
        }


                                        ) 

我想将此SQL转换为linq，我正在尝试转换它，但它会抛出异常。 有人可以帮忙吗？ 提前致谢
