Question

I have the following code:

var allWorkorders =

            (from wo in context.WORKORDERs
            join wot in context.WORKORDERTYPEs on wo.wot_oi equals wot.wotyoi
            join pri in context.PRIORITies on wo.prio_oi equals pri.priooi
            join s in context.SITEs on wo.BEparn_oi equals s.siteoi
            where wo.audt_created_dttm.Value.Year >= now.Year - 3 && wo.audt_created_dttm.Value.Year >= 2006
                && wo.audt_created_dttm < timeframe && (s.id == "NM" || s.id == "TH") &&
                (wo.clsdt_date ?? new DateTime(3000, 01, 01)) < DateTime.Now
            group pri by new {s.id, pri.prioid, MonthNum = (wo.clsdt_date ?? new DateTime(3000, 01, 01)).Year * 100 +
                (wo.clsdt_date ?? new DateTime(3000, 01, 01)).Month} into groupItem
            orderby groupItem.Key.MonthNum, groupItem.Key.id
            select new {groupItem.Key.id, groupItem.Key.prioid, groupItem.Key.MonthNum, Unit = groupItem.Count()});

            allWorkorders.GroupBy(x => new { x.id, x.MonthNum }).Select(x => new {x.Key.id, x.Key.MonthNum,
            Denominator = x.Sum(y => y.Unit), Numerator = x.Where(y => SqlMethods.Like(y.prioid, "1%") || 
            SqlMethods.Like(y.prioid, "6%")).Sum(y => y.Unit), Data_Indicator = DATA_INDICATOR,
            Budgeted = budgetedPlannedOutageHrs, Industry_Benchmark = INDUSTRY_BENCHMARK,
            Comments = comments, Executive_Comments = executiveComments, 
            Fleet_Exec_Comments = fleetExecComments}).ToList();

I want to create a for loop:

for (int counter = 0; counter < allWorkorders.Count; counter++)
{
    var item = allWorkorders[counter];
    ......

However, I get the following error: ” ‘<‘ cannot be applied to operands of type ‘int’ and ‘method group'”

So even though I have allWorkorders going to ToList() it’s not being recognized as a list.

What am I doing wrong? I have done this in the past, the biggest difference being that in the past cases my ToList was at the end of the select statement.

Answer 1

ToList() returns a result. You need something like

var newList = allWorkorders.GroupBy(x => ...).Select(x => ...).ToList();
